将多个值从单个文本框保存并返回到单个XML文件。 [英] Save and Return multiple values from a single text box to single XML file.

问题描述

我正在一个小项目中工作，而不是所有编程方面的专家。



有一定要求我必须从单个文本中保存条目框到一个XML文件，并在需要时将它们返回到另一个多行文本框。

一行中的每个条目。

IE

toolstriptextbox_1条目1 = abc

条目2 = xyz



等..



我的代码（下面）设法将条目保存到XML文件，但它会复制相同的第一个条目，而不是每次文本框中的新条目更改时捕获不同的条目。



这是代码的一部分。涉及此操作。



\\保存部分\\创建它作为一个单独的类。



命名空间HW_Browser

{

公共类SaveXml

{

public static void Saveurl（object myurl，string filename）

{

XmlSerializer sr = new XmlSerializer（myurl.GetType（））;

TextWriter writer = new StreamWriter（filename ）;

sr.Serialize（作家，myurl）;

writer.Close（）;



}



}

}

+++++++++++++++++++++++++++++++++++++++++ ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++这确实是这样，但我知道\\it的单独类也处理XML文件的读写。

  set  {entry1 =  value ; }

  get  { return  entry2; } 
  set  {entry2 =  value ; }

  public   string  Entry3

  get  { return  entry3; } 
  set  {entry3 =  value ; }

 read.Close（）; 
} 

解决方案

获取文本框的行如下

  if （toolStripTextBox1.Lines.Length> 0）
 his.Entry1 = toolStripTextBox1.Lines [ 0 ]; 
  if （toolStripTextBox1.Lines.Length> 1）
 his.Entry2 = toolStripTextBox1.Lines [ 1 ]; 
  if （toolStripTextBox1.Lines.Length> 2）
 his.Entry3 = toolStripTextBox1.Lines [ 2 ]; 
  if （toolStripTextBox1.Lines.Length> 3）
 his.Entry4 = toolStripTextBox1.Lines [ 3 ]; 

设置如下行

 toolStripTextBox1.Text = his.Entry1 + Environment.NewLine 
 + his.Entry2 + Environment.NewLine 
 + his.Entry3 + Environment.NewLine 
 + his.Entry4 + Environment.NewLine; 

I am working in a small project , not at all expert in programming.

There is a certain requirement where in I have to save entries from a single text box to an XML file and return them back when required to a different Multi-line text box.
Each entry in a line.
IE
toolstriptextbox_1 Entry 1 = abc
Entry 2 = xyz

etc..

My code (below) managed to save entries to the XML file, however it duplicates the same first entry rather than capturing different entries each time a new entry in the text box changes.

Here is the portion of the code. that involves this operation.

\\ The saving parts\\ created it as a separate class.

namespace HW_Browser
{
public class SaveXml
{
public static void Saveurl(object myurl, string filename)
{
XmlSerializer sr = new XmlSerializer(myurl.GetType());
TextWriter writer = new StreamWriter(filename);
sr.Serialize(writer, myurl);
writer.Close();

}

}
}

\\Not sure what this exactly does but I know \\it's separate class as well deals with the XML file reading and writing.

namespace HW_Browser
{
   public class browsinghistory
    {
        private string entry1;
        private string entry2;
        private string entry3;
        private string entry4;

        public string Entry1
        {
            get { return entry1; }
            set { entry1 = value; }
        }
        public string Entry2
        {
            get { return entry2; }
            set { entry2 = value; }
        }
        public string Entry3
        {
            get { return entry3; }
            set { entry3 = value; }
        }
        public string Entry4
        {
            get { return entry4; }
            set { entry4 = value; }
        }

    }
}

\\here is where it gets saved to the XML file \\ triggered by a button click 
try
            {
                
                

                browsinghistory his = new browsinghistory();
                his.Entry1 = toolStripTextBox1.Text;
                his.Entry2 = toolStripTextBox1.Text;
                his.Entry3 = toolStripTextBox1.Text;
                his.Entry4 = toolStripTextBox1.Text;
                SaveXml.Saveurl(his, "history.xml");

  
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }

\\ This is where the XML file supposed to displays the value back to the other multi-line text box.

if (File.Exists("history.xml"))
            {
                XmlSerializer xs = new XmlSerializer(typeof(browsinghistory));
                FileStream read = new FileStream("history.xml", FileMode.Open, FileAccess.Read, FileShare.Read);
                browsinghistory his = (browsinghistory)xs.Deserialize(read);
                textBox1.Text = his.Entry1;
                textBox1.Text = his.Entry2;
                textBox1.Text = his.Entry3;
                textBox1.Text = his.Entry4;
                read.Close();
            }

解决方案

get lines of the text box as below

if(toolStripTextBox1.Lines.Length >0)
  his.Entry1 = toolStripTextBox1.Lines[0];
if(toolStripTextBox1.Lines.Length >1)
   his.Entry2 = toolStripTextBox1.Lines[1];
if(toolStripTextBox1.Lines.Length >2)
  his.Entry3 = toolStripTextBox1.Lines[2];
if(toolStripTextBox1.Lines.Length >3)
  his.Entry4 = toolStripTextBox1.Lines[3];

set lines as below

toolStripTextBox1.Text = his.Entry1 + Environment.NewLine 
                         + his.Entry2 + Environment.NewLine 
                         + his.Entry3 + Environment.NewLine 
                         + his.Entry4 + Environment.NewLine;
