Question

使用DataContractSerializer时，我无法获取xml输出以匹配C＃合同。

以下是相互嵌套的具有不同名称空间的示例类。

[DataContract(Name = "TestClass", Namespace = "http://testclass.com")]
public class TestClass
{
    [DataMember]
    public PropertyOne PropertyOne { get; set; }
    [DataMember]
    public PropertyTwo PropertyTwo { get; set; }
}

[DataContract(Name = "PropertyOne", Namespace = "http://propertyone.com")]
public class PropertyOne
{
    [DataMember]
    public ExtendedPropertyOne ExtendedPropertyOne { get; set; }
}

[DataContract(Name = "PropertyTwo", Namespace = "http://propertytwo.com")]
public class PropertyTwo
{
    [DataMember]
    public ExtendedPropertyTwo ExtendedPropertyTwo { get; set; }
}

[DataContract(Name = "ExtendedPropertyOne", Namespace = "http://propertyone.com")]
public class ExtendedPropertyOne
{

}
[DataContract(Name = "ExtendedPropertyTwo", Namespace = "http://propertytwo.com")]
public class ExtendedPropertyTwo
{

}

然后设置对象：

var testclass = new TestClass()
{
    PropertyOne = new PropertyOne { ExtendedPropertyOne = new ExtendedPropertyOne() },
    PropertyTwo = new PropertyTwo { ExtendedPropertyTwo = new ExtendedPropertyTwo() }
};

我使用DataContractSerializer如下：

public static string SerializeAsXml<T>(T data)
{
    var sb = new StringBuilder();

    var xmlSettings = new XmlWriterSettings()
    {
        OmitXmlDeclaration = true,
        Indent = true
    };

    using (var xw = XmlWriter.Create(sb, xmlSettings))
    {
        new DataContractSerializer(typeof(T)).WriteObject(xw, data);
    }

    return sb.ToString();
}

我得到以下输出，请注意，当C＃协定分别在propertyone和propertytwo命名空间中指定默认名称空间时，在默认名称空间testclass.com中定义了PropertyOne和PropertyTwo元素。

<TestClass xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://testclass.com">
  <PropertyOne xmlns:d2p1="http://propertyone.com">
    <d2p1:ExtendedPropertyOne />
  </PropertyOne>
  <PropertyTwo xmlns:d2p1="http://propertytwo.com">
    <d2p1:ExtendedPropertyTwo />
  </PropertyTwo>
</TestClass>

预期输出为：

<TestClass xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://testclass.com">
  <d2p1:PropertyOne xmlns:d2p1="http://propertyone.com">
    <d2p1:ExtendedPropertyOne />
  </d2p1:PropertyOne>
  <d2p2:PropertyTwo xmlns:d2p2="http://propertytwo.com">
    <d2p2:ExtendedPropertyTwo />
  </d2p2:PropertyTwo>
</TestClass>

在正确的名称空间中使用PropertyOne和PropertyTwo类。

这会导致合同验证出现问题，这是错误还是已知限制？

DataContractSerializer序列化的类与合同不匹配
