从基于条件的列表中创建一个XML文件 [英] Create a XML File from a list based on a conditional

问题描述

我一直试图了解，几个小时，但没有运气。
我有一个基于类的列表：

  public class xmldata //接收项目列表的列表
 {
 public string xml_filename {get;组; } 
 public string colorname {get;组; } 
 public string colorvalues {get;组; } 
 
 
 
 
 $ b然后我做了一个分离的类来保存列表：  
 
 
  public class xmldatalist 
 {
 public List< xmldata> FullList = new List< xmldata>（）; 
 
 
 
 $ b $ p 
 $ b这个列表的每个位置（FullList）包含xmldata的三个元素 - 我想问的一个问题是xml_filename。我的问题是：我怎么能有一个foreach循环遍历这个列表，并为每个xml_filename值生成一个XML文件。 
从位置0到5，xml_filename是file1.bla 
从位置6到9，xml_filename是file2.bla 
 
 
 
我想要一个将循环遍历位置0到5的foreach，检查xml_filename是否为file1.bla，并写入位于0到5的属性。 
 
 
 
 类似于： 
 
 
检查xml_filename 
创建文件
写属性
如果xml_filename在下一个位置相同
继续在这个文件上写
如果xml_file在下一个位置不同，写新文件
 
 
现在我正在尝试使用Linq，做到这一点：$ b​​ 
 $ b 
  foreach（var ListXmlFileName in XMLList.FullList.Where（x => xml_filename == XmlFilename））
 {
} 
  
有点不知所措。 
我试过的另一种方法是：
 $ b $ $ $ $ $ $ $ $ $ b $ $ $ $ $ $ $ $ $ 
 $ b  
没有成功。编写XML的代码是：
 
 pre $ public $ write $ xml xmlItems，变量GlobalVars 
 {
 XmlWriterSettings settings = new XmlWriterSettings 
 {
 Indent = true，
 IndentChars =\t，
 NewLineChars = Environment.NewLine，
 NewLineHandling = NewLineHandling.Replace ，
 Encoding = new UTF8Encoding（false）
}; 
 int pos = 0; 
 
 
 $ b foreach（XmlItems.ItemsList中的XmlStuff）
 {
 
字符串DesktopFolder = Environment.GetFolderPath（Environment.SpecialFolder.DesktopDirectory ）; 
 string XmlFilename =dadada; 
字符串FileExtension =.xml; 
 string PathString = Path.Combine（DesktopFolder，XML）; 
 System.IO.Directory.CreateDirectory（PathString）; 
 string FullPath = Path.Combine（PathString，XmlFilename + FileExtension）; 
 
 XmlWriter XmlWriting = XmlWriter.Create（FullPath，settings）; 
 
 XmlWriting.WriteStartDocument（）; 
 XmlWriting.WriteStartElement（JMF）; 
 XmlWriting.WriteAttributeString（SenderID，InkZone-Controller）; 
 XmlWriting.WriteAttributeString（Version，1.2）; 
 //XmlWriting.WriteAttributeString(\"xmlns\",\"\"nn，http://www.CIP4.org/JDFSchema_1_1）; 
 
 XmlWriting.WriteStartElement（Command）; 
 XmlWriting.WriteAttributeString（ID，cmd.00695）; 
 XmlWriting.WriteAttributeString（Type，Resource）; 
 
 
 XmlWriting.WriteStartElement（ResourceCMDParams）; 
 XmlWriting.WriteAttributeString（ResourceName，InkZoneProfile）; 
 XmlWriting.WriteAttributeString（JobID，K_41）; 
 
 
 XmlWriting.WriteStartElement（InkZoneProfile）; 
 XmlWriting.WriteAttributeString（ID，r0013）; 
 XmlWriting.WriteAttributeString（Class，Parameter）; 
 XmlWriting.WriteAttributeString（Locked，false）; 
 XmlWriting.WriteAttributeString（Status，Available）; 
 XmlWriting.WriteAttributeString（PartIDKeys，SignatureName SheetName Side Separation）; 
 XmlWriting.WriteAttributeString（DescriptiveName，Schieberwerte von DI）; 
 XmlWriting.WriteAttributeString（ZoneWidth，32）; 
 
 
 XmlWriting.WriteStartElement（InkZoneProfile）; 
 XmlWriting.WriteAttributeString（SignatureName，SIG1）; 
 
 XmlWriting.WriteStartElement（InkZoneProfile）; 
 XmlWriting.WriteAttributeString（Locked，False）; 
 XmlWriting.WriteAttributeString（SheetName，S1）; 
 
 XmlWriting.WriteStartElement（InkZoneProfile）; 
 XmlWriting.WriteAttributeString（Side，Front）; 
  

我也试过，但没有按预期工作（while循环）

  while（XmlStuff.xml_filename == XmlItems.ItemsList [pos] .xml_filename）
 {
 XmlWriting.WriteStartElement InkZoneProfile）; 
 XmlWriting.WriteAttributeString（Separation，XmlItems.ItemsList [pos] .colorname）; 
 XmlWriting.WriteAttributeString（ZoneSettingsX，XmlItems.ItemsList [pos] .colorvalues）; 
 XmlWriting.WriteEndElement（）; 
 pos ++; 
} 
 XmlWriting.WriteEndDocument（）; 
 XmlWriting.Close（）; 
 
 
 
 
 $ b $ p $任何帮助将非常感谢。

解决方案
这就是你想要的：  
 
 
  [可序列化] 
 [XmlType（InkZoneProfile）] 
 public class xmldata接收物品清单
 {
 [XmlIgnore] 
公共字符串xml_filename {get;组; } 
 
 [XmlAttribute（Separation）] 
 public string colorname {get;组; } 
 
 [XmlAttribute（ZoneSettingsX）] 
 public string colorvalues {get;组; （new xmldata {xml_filename = @D：\File_One，colorname =Red，colorvalues =＃FF0000}）;} 
 
 
 $ b FullList.Add ; 
 FullList.Add（new xmldata {xml_filename = @D：\File_One，colorname =Blue，colorvalues =＃0000FF}）; 
 FullList.Add（new xmldata {xml_filename = @D：\File_Two，colorname =Black，colorvalues =＃000000}）; 
 FullList.Add（new xmldata {xml_filename = @D：\File_Two，colorname =White，colorvalues =#FFFFFF}）; 
 
 Dictionary< string，List< xmldata>> xmlFiles = new Dictionary< string，List< xmldata>>（）; 
 foreach（FullList中的var项）
 {
 if（！xmlFiles.ContainsKey（item.xml_filename））xmlFiles [item.xml_filename] = new List >（）; 
 xmlFiles [item.xml_filename] .Add（item）; 
} 
 
 foreach（var i in xmlFiles）
 {
 string yourXMLFileName = i.Key; 
列出< xmldata> xmlDataOfThisFile = i.Value; 
 Console.WriteLine（yourXMLFileName）; 
使用（FileStream fs = new FileStream（yourXMLFileName，FileMode.Create，FileAccess.Write，FileShare.None））
尝试
 {
）
 {
 XmlSerializer serializer = new XmlSerializer的（typeof运算（列表与LT; XMLDATA>））; 
 serializer.Serialize（fs，FullList）; 
 
 $ b $ catch（Exception ex）
 {
 Console.WriteLine（ex.Message）; 
 Console.WriteLine（ex.InnerException）; 
 
 
 
 
 
 
 $ p $这将创建这个XML：
 <？xml version =1.0？> 
< ArrayOfInkZoneProfile xmlns：xsi =http://www.w3.org/2001/XMLSchema-instancexmlns：xsd =http://www.w3.org/2001/XMLSchema> 
< InkZoneProfile Separation =RedZoneSettingsX =＃FF0000/> 
< InkZoneProfile Separation =BlueZoneSettingsX =＃0000FF/> 
< InkZoneProfile Separation =BlackZoneSettingsX =＃000000/> 
< InkZoneProfile Separation =WhiteZoneSettingsX =＃FFFFFF/> 
< / ArrayOfInkZoneProfile>

 <根据你的评论，你有其他问题。如果题目问题现在解决了，你应该问一个新的问题。不要在这里结合它。
 
I've been trying to understand that for several hours but got no luck. 
I've a list based on a class:
public class xmldata //Class to receive items list
{
    public string xml_filename { get; set; }
    public string colorname { get; set; }
    public string colorvalues { get; set; }

}
Then i made a separated class to hold the list:
public class xmldatalist
{
    public List<xmldata> FullList = new List<xmldata>();
}
Each position of this list (FullList) contains three elements from xmldata - the specific one i want to focus is xml_filename.

My question is: How could i have a foreach loop to iterate over this list , and generate one XML file for each xml_filename value.

i.e:
From positions 0 to 5 , xml_filename is file1.bla
From positions 6 to 9 , xml_filename is file2.bla

I want a foreach that will iterate trough positions 0 to 5 , check that xml_filename is file1.bla and write attributes who are on position 0 to 5.

Something like:

Check xml_filename
Create the file
Write Attributes
if xml_filename is the same on the next position
keep writing on this file
if xml_file is different on the next position, write new file

Right now i was trying to use Linq, by doing this:
foreach (var ListXmlFileName in XMLList.FullList.Where(x => x.xml_filename == XmlFilename))
{
}
But i'm kinda lost on how to proceed.
Another approach i tried was:
foreach (xmldata XmlStuff in XmlItems.ItemsList)
{
}
Without success also. The code for writing the XML is:
public void writexml(xmldatalist XmlItems, variables GlobalVars)
{
    XmlWriterSettings settings = new XmlWriterSettings
    {
        Indent = true,
        IndentChars = "\t",
        NewLineChars = Environment.NewLine,
        NewLineHandling = NewLineHandling.Replace,
        Encoding = new UTF8Encoding(false)
    };
    int pos = 0;



    foreach (xmldata XmlStuff in XmlItems.ItemsList)
    {

        string DesktopFolder = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory);
        string XmlFilename = "dadada";
        string FileExtension = ".xml";
        string PathString = Path.Combine(DesktopFolder, "XML");
        System.IO.Directory.CreateDirectory(PathString);
        string FullPath = Path.Combine(PathString, XmlFilename + FileExtension);

        XmlWriter XmlWriting = XmlWriter.Create(FullPath, settings);

            XmlWriting.WriteStartDocument();
            XmlWriting.WriteStartElement("JMF");
            XmlWriting.WriteAttributeString("SenderID", "InkZone-Controller");
            XmlWriting.WriteAttributeString("Version", "1.2");
            //XmlWriting.WriteAttributeString("xmlns","",null, "http://www.CIP4.org/JDFSchema_1_1");

            XmlWriting.WriteStartElement("Command");
            XmlWriting.WriteAttributeString("ID", "cmd.00695");
            XmlWriting.WriteAttributeString("Type", "Resource");


            XmlWriting.WriteStartElement("ResourceCMDParams");
            XmlWriting.WriteAttributeString("ResourceName", "InkZoneProfile");
            XmlWriting.WriteAttributeString("JobID", "K_41");


            XmlWriting.WriteStartElement("InkZoneProfile");
            XmlWriting.WriteAttributeString("ID", "r0013");
            XmlWriting.WriteAttributeString("Class", "Parameter");
            XmlWriting.WriteAttributeString("Locked", "false");
            XmlWriting.WriteAttributeString("Status", "Available");
            XmlWriting.WriteAttributeString("PartIDKeys", "SignatureName SheetName Side Separation");
            XmlWriting.WriteAttributeString("DescriptiveName", "Schieberwerte von DI");
            XmlWriting.WriteAttributeString("ZoneWidth", "32");


            XmlWriting.WriteStartElement("InkZoneProfile");
            XmlWriting.WriteAttributeString("SignatureName", "SIG1");

            XmlWriting.WriteStartElement("InkZoneProfile");
            XmlWriting.WriteAttributeString("Locked", "False");
            XmlWriting.WriteAttributeString("SheetName", "S1");

            XmlWriting.WriteStartElement("InkZoneProfile");
            XmlWriting.WriteAttributeString("Side", "Front");
I've tried this too but didn't worked as expected(The while loop)
       while(XmlStuff.xml_filename == XmlItems.ItemsList[pos].xml_filename)
        {
            XmlWriting.WriteStartElement("InkZoneProfile");
            XmlWriting.WriteAttributeString("Separation", XmlItems.ItemsList[pos].colorname);
            XmlWriting.WriteAttributeString("ZoneSettingsX", XmlItems.ItemsList[pos].colorvalues);
            XmlWriting.WriteEndElement();
            pos++;
        }
    XmlWriting.WriteEndDocument();
    XmlWriting.Close();     
    }
}
Any help will be greately appreciated. Thanks a lot.

Lets suppose this belongs to file1. File1 will have five 
SomeColor and SomeValues are in each position of the list.
解决方案
Is this what you want:
[Serializable]
[XmlType("InkZoneProfile")]
public class xmldata //Class to receive items list
{
    [XmlIgnore]
    public string xml_filename { get; set; }

    [XmlAttribute("Separation")]
    public string colorname { get; set; }

    [XmlAttribute("ZoneSettingsX")]
    public string colorvalues { get; set; }

}

FullList.Add(new xmldata { xml_filename = @"D:\File_One", colorname = "Red", colorvalues = "#FF0000" });
FullList.Add(new xmldata { xml_filename = @"D:\File_One", colorname = "Blue", colorvalues = "#0000FF" });
FullList.Add(new xmldata { xml_filename = @"D:\File_Two", colorname = "Black", colorvalues = "#000000" });
FullList.Add(new xmldata { xml_filename = @"D:\File_Two", colorname = "White", colorvalues = "#FFFFFF" });

Dictionary<string, List<xmldata>> xmlFiles = new Dictionary<string, List<xmldata>>();
foreach (var item in FullList)
{
    if (!xmlFiles.ContainsKey(item.xml_filename)) xmlFiles[item.xml_filename] = new List<xmldata>();
    xmlFiles[item.xml_filename].Add(item);
}

foreach (var i in xmlFiles)
{
    string yourXMLFileName = i.Key;
    List<xmldata> xmlDataOfThisFile = i.Value;
    Console.WriteLine(yourXMLFileName);
    try
    {
        using (FileStream fs = new FileStream(yourXMLFileName, FileMode.Create, FileAccess.Write, FileShare.None))
        {
            XmlSerializer serializer = new XmlSerializer(typeof(List<xmldata>));
            serializer.Serialize(fs, FullList);
        }
    }
    catch(Exception ex)
    {
        Console.WriteLine(ex.Message);
        Console.WriteLine(ex.InnerException);
    }
}
This will create this XML:
<?xml version="1.0"?>
<ArrayOfInkZoneProfile xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <InkZoneProfile Separation="Red" ZoneSettingsX="#FF0000" />
  <InkZoneProfile Separation="Blue" ZoneSettingsX="#0000FF" />
  <InkZoneProfile Separation="Black" ZoneSettingsX="#000000" />
  <InkZoneProfile Separation="White" ZoneSettingsX="#FFFFFF" />
</ArrayOfInkZoneProfile>
