枚举的XML序列化 [英] XML serialization of enums

问题描述

这是代码：

 
我有序列化枚举值的问题。 code> [System.Xml.Serialization.XmlRootAttribute（Namespace =，IsNullable = false）] 
 public class REQUEST 
 {
 [System.Xml.Serialization.XmlAttributeAttribute（） ] 
 public string ID; 
 
 [System.Xml.Serialization.XmlAttributeAttribute（）] 
 public REQUESTTypetype类型; 
} 
 
公开枚举REQUESTTypetype 
 {
一，
二，
三，
四，
} 
 
 ... 
 
 REQUEST request = new REQUEST（）; 
 request.ID =1234; 
 request.Type = REQUESTTypetype.One; 
 
 XmlDocument doc = new XmlDocument（）; 
 MemoryStream ms = new MemoryStream（）; 
 StreamWriter sw = new StreamWriter（ms）; 
 XmlSerializer xs = new XmlSerializer（typeof（REQUEST））; 
 xs.Serialize（sw，request_group）; 
 ms.Position = 0; 
 doc.Load（ms）; 
 TestWriteXml（doc，@C：\xml_test.xml）; 
  

结果是：

 <？xml version =1.0encoding =utf-8？> 
< REQUEST ID =1234/> 
  

为什么枚举不是序列化的？我使用.NET Framework 2.0。

谢谢。

解决方案

我发现有什么问题对于每个枚举类型

  [System.Xml.Serialization.XmlAttributeAttribute（）] 
 public REQUESTTypetype类型; 
  

我得到这个：

  [System.Xml.Serialization.XmlIgnoreAttribute（）] 
 public bool TypeSpecified; 
  

在代码中我应该这样做：

  request.Type = REQUESTTypetype.One; 
 request.TypeSpecified = true; 
  

现在可以正常工作。我应该在我的问题上发表他们，但我没有注意这些指定的成员。
感谢您的回复。

I have problems with serializing enum values.

Here is the code:

[System.Xml.Serialization.XmlRootAttribute(Namespace = "", IsNullable = false)]
public class REQUEST
{
    [System.Xml.Serialization.XmlAttributeAttribute()]
    public string ID;

    [System.Xml.Serialization.XmlAttributeAttribute()]
    public REQUESTTypetype Type;
}

public enum REQUESTTypetype
{
    One,
    Two,
    Three,
    Four,
}

...

REQUEST request = new REQUEST();
request.ID = "1234";
request.Type = REQUESTTypetype.One;

XmlDocument doc = new XmlDocument();
MemoryStream ms = new MemoryStream();
StreamWriter sw = new StreamWriter(ms);
XmlSerializer xs = new XmlSerializer(typeof(REQUEST));
xs.Serialize(sw, request_group);
ms.Position = 0;
doc.Load(ms);
TestWriteXml(doc, @"C:\xml_test.xml");

The result is:

<?xml version="1.0" encoding="utf-8" ?> 
<REQUEST ID="1234" />

Why the enum is not serialized? I use .NET Framework 2.0.

Thank you.

解决方案

I found what was wrong. For every enum type

[System.Xml.Serialization.XmlAttributeAttribute()]
public REQUESTTypetype Type;

I got this:

[System.Xml.Serialization.XmlIgnoreAttribute()]
public bool TypeSpecified;

And in the code I should do this:

request.Type = REQUESTTypetype.One;
request.TypeSpecified = true;

It works fine now. I should have post them in my question but I did not pay attention to these "specified" members at all. Thanks for your replies.
