我可以做的XmlSerializer忽略命名空间（xmlns属性）的反序列化，这样，如果属性添加与否，甚至如果属性是假的也没关系？我知道的源将总是可信的，所以我不关心xmlns属性。

Can I make XmlSerializer ignore the namespace (xmlns attribute) on deserialization so that it doesn't matter if the attribute is added or not or even if the attribute is bogus? I know that the source will always be trusted so I don't care about the xmlns attribute.

推荐答案

是的，你可以告诉XmlSerializer的忽略在反序列化的命名空间。

Yes, you can tell the XmlSerializer to ignore namespaces during de-serialization.

定义忽略命名空间的一个XmlTextReader。像这样：

Define an XmlTextReader that ignores namespaces. Like so:

// helper class to ignore namespaces when de-serializing
public class NamespaceIgnorantXmlTextReader : XmlTextReader
{
    public NamespaceIgnorantXmlTextReader(System.IO.TextReader reader): base(reader) { }

    public override string NamespaceURI
    {
        get { return ""; }
    }
}

// helper class to omit XML decl at start of document when serializing
public class XTWFND  : XmlTextWriter {
    public XTWFND (System.IO.TextWriter w) : base(w) { Formatting= System.Xml.Formatting.Indented;}
    public override void WriteStartDocument () { }
}

下面是使用的TextReader你会如何反序列化的一个例子：

Here's an example of how you would de-serialize using that TextReader:

public class MyType1 
{
    public string Label
    {
        set {  _Label= value; } 
        get { return _Label; } 
    }

    private int _Epoch;
    public int Epoch
    {
        set {  _Epoch= value; } 
        get { return _Epoch; } 
    }        
}



    String RawXml_WithNamespaces = @"
      <MyType1 xmlns='urn:booboo-dee-doo'>
        <Label>This document has namespaces on its elements</Label>
        <Epoch xmlns='urn:aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa'>0</Epoch>
      </MyType1>";


    System.IO.StringReader sr;
    sr= new System.IO.StringReader(RawXml_WithNamespaces);
    var o1= (MyType1) s1.Deserialize(new NamespaceIgnorantXmlTextReader(sr));
    System.Console.WriteLine("nnDe-serialized, then serialized again:n");
    s1.Serialize(new XTWFND(System.Console.Out), o1, ns);
    Console.WriteLine("nn");

其结果是，像这样：

The result is like so:

    <MyType1>
      <Label>This document has namespaces on its elements</Label>
      <Epoch>0</Epoch>
    </MyType1>
