Xml 序列化和编写器 [英] Xml Serializing and Writer
问题描述
在我用按钮创建的一个类中单击一个 XML 文档:
in one class I create with a button click a XML document:
private void buttonCreate_Click(object sender, RoutedEventArgs e)
{
DialogResult result = folderElg.ShowDialog();
if (result == System.Windows.Forms.DialogResult.OK)
{
textBoxPath.Text = folderElg.SelectedPath;
userConfigurePath = folderElg.SelectedPath;
}
XmlDocument toolConfig = new XmlDocument();
XmlNode myRoot;
myRoot = toolConfig.CreateElement("Tool");
toolConfig.AppendChild(myRoot);
toolConfig.Save(@userConfigurePath + "\\config.xml");}
我没有问题.文件夹已创建,xml 文件也已创建.
There I haven't problems. The folder is created and the xml file also.
所以在另一个类中,我想将对象序列化到 xml 文件config.xml"中(变量 userConfigurePath 在上面提到的类中是静态的):
So in an other class I want to serialize objects into the xml file 'config.xml' (The variable userConfigurePath is static in the classe mentionned above):
public partial class MainWindow : Window
{
private string inputNewTool = "";
private OpenFileDialog dlg = new OpenFileDialog();
public MainWindow()
{
InitializeComponent();
}
private void buttonAdd_Click(object sender, RoutedEventArgs e)
{
InputDialog input = new InputDialog();
input.ShowDialog();
inputNewTool = input.enteredTxt;
if (inputNewTool != null)
{
System.Windows.Forms.MessageBox.Show("Chose the Tool's directory");
dlg.DefaultExt = ".txt";
dlg.Filter = "Text documents (.txt)|*.txt";
if (dlg.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
Tool tool = new Tool();
tool.Name = inputNewTool;
tool.Path = dlg.FileName;
XmlSerializer serializer = new XmlSerializer(tool.GetType());
StreamWriter writer = new StreamWriter(@Start.userConfigurePath +
"\\config.xml");
serializer.Serialize(writer.BaseStream, tool);
}
}
结果是对象没有保存在 config.xml 文件中.为什么?
The result is that the object isn't saved in the config.xml file. Why?
编辑工具的类:
public class Tool
{
public string Name { get; set; }
public string Path { get; set; }
public Tool() { }
}
第二次
我发现在创建 xml 文件时,我无法删除 manuel 这些文件夹(在应用程序关闭后).为什么?
I see that i can't delete manuel these folder (after the application is closed) with the xml file when it is created. Why?
第三次
我更改了代码:
if (dlg.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
Tool tool = new Tool();
tool.Name = inputNewTool;
tool.Path = dlg.FileName;
XmlSerializer serializer = new XmlSerializer(tool.GetType());
using (var writer = new StreamWriter(@Start.userConfigurePath +
"\\config.xml"))
{
serializer.Serialize(writer.BaseStream, tool);
writer.Close();
}
现在第一个对象被序列化了.但是如果我以同样的方式创建另一个工具,config.xml 就不会接受它.只序列化了第一个工具:
Now the first object is serialized. But if i create another tool in the same way the config.xml doesn't take it. Only the first tool is serialized:
<?xml version="1.0"?>
<Tool xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<Name>dffss</Name>
<Path>D:\Users\xxxx\Documents\schulewochenbericht.txt</Path>
</Tool>
推荐答案
您需要关闭 StreamWriter 对象才能将数据刷新到文件中.请尝试以下操作:
You need to close the StreamWriter object to flush the data into the file. Please try the following:
XmlSerializer serializer = new XmlSerializer(tool.GetType());
using (var writer = new StreamWriter(@Start.userConfigurePath + "\\config.xml"))
{
serializer.Serialize(writer.BaseStream, tool);
}
