当字符串字段值为空格时，XMLSerializer 中出现问题

使用 XMLSerializer 保存从 myClass 这样的类创建的对象

Public Class MyClass
{
  Public String test = " " ;
}

将导致：

<MyClass>
  <test> </test>
</MyClass>

但是当我想加载 xml 文件时，它看起来像是删除了我需要的空白。我该如何解决这个问题？谢谢

原文

using XMLSerializer for saving an object created from a class like myClass

Public Class MyClass
{
  Public String test = " " ;
}

will result :

<MyClass>
  <test> </test>
</MyClass>

but when I want to load the xml file looks like it's removing the white space ,which I need .
How can I solve this problem ?
thanks

无法重现 - 看起来很好：

using System;
using System.IO;
using System.Xml;
using System.Xml.Serialization;

public class MyClass
{
    [XmlElement("test")]
    public string Test { get; set; }
}
static class Program
{
    static void Main()
    {
        XmlSerializer ser = new XmlSerializer(typeof(MyClass));
        MyClass orig = new MyClass { Test = " " }, clone;
        using (var file = XmlWriter.Create("my.xml"))
        {
            ser.Serialize(file, orig);
        }
        using (var file = XmlReader.Create("my.xml"))
        {
            clone = (MyClass)ser.Deserialize(file);
        }
        Console.WriteLine("'" + clone.Test + "'");
        Console.WriteLine(File.ReadAllText("my.xml"));
    }
}

输出：

' '

并且

<?xml version="1.0" encoding="utf-8"?><MyClass xmlns:xsi="http://www.w3.org/2001
/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><test> </test>
</MyClass>

它可能有助于更具体地说明您如何尝试查看它，这样它“看起来像是在删除空白”。

Cannot reproduce - it seems fine:

using System;
using System.IO;
using System.Xml;
using System.Xml.Serialization;

public class MyClass
{
    [XmlElement("test")]
    public string Test { get; set; }
}
static class Program
{
    static void Main()
    {
        XmlSerializer ser = new XmlSerializer(typeof(MyClass));
        MyClass orig = new MyClass { Test = " " }, clone;
        using (var file = XmlWriter.Create("my.xml"))
        {
            ser.Serialize(file, orig);
        }
        using (var file = XmlReader.Create("my.xml"))
        {
            clone = (MyClass)ser.Deserialize(file);
        }
        Console.WriteLine("'" + clone.Test + "'");
        Console.WriteLine(File.ReadAllText("my.xml"));
    }
}

outputs:

' '

and

<?xml version="1.0" encoding="utf-8"?><MyClass xmlns:xsi="http://www.w3.org/2001
/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><test> </test>
</MyClass>

It might help to be more specific about how you are trying to view it, such that it "looks like it's removing the white space".
