Question

在应用程序中，我有以下接口/实现结构：

public interface IMyInterface
{
  IMyOtherInterface InstanceOfMyOtherInterface { get; }
}

public interface IMyOtherInterface
{
  string SomeValue { get; }
}

[DataContract(Name = "MyInterfaceImplementation", Namespace = "")]
public class MyInterfaceImplementation : IMyInterface
{
  [DataMember(EmitDefaultValue = false), XmlAttribute(Namespace = "")]
  public IMyOtherInterface InstanceOfMyOtherInterface { get; private set; }

  public MyInterfaceImplementation()
  {
    this.InstanceOfMyOtherInterface = new MyOtherInterfaceImplementation("Hello World");
  }
}

[DataContract(Name = "MyOtherInterfaceImplementation", Namespace = "")]
public class MyOtherInterfaceImplementation : IMyOtherInterface
{
  [DataMember]
  public string SomeValue { get; private set; }

  public MyOtherInterfaceImplementation(string value)
  {
    this.SomeValue = value; 
  }
}

现在，只要我使用.Net DataContractSerializer将此序列化（在我的情况下为字符串），就像这样：

var dataContractSerializer = new DataContractSerializer(typeof(MyInterfaceImplementation));
var stringBuilder = new StringBuilder();
using (var xmlWriter = XmlWriter.Create(stringBuilder, new XmlWriterSettings { Indent = true, Encoding = Encoding.UTF8 }))
{
  dataContractSerializer.WriteObject(xmlWriter, this);
}
var stringValue = stringBuilder.ToString();

生成的xml看起来非常像这样：

<?xml version="1.0" encoding="utf-16"?>
<z:anyType xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="" i:type="MyInterfaceImplementation" xmlns:z="http://schemas.microsoft.com/2003/10/Serialization/">
  <InstanceOfMyOtherInterface xmlns="" i:type="InstanceOfMyOtherInterface">
    <SomeValue>Hello World</SomeValue>
  </InstanceOfMyOtherInterface>
</z:anyType>

这些* anyType *似乎来自datacontractserializer，它将MyInterfaceImplementation实例序列化为System.Object，同样具有其他接口属性。

如果我在我的界面中使用具体类型及其实现如下：

public interface IMyInterface
{
  MyOtherInterface InstanceOfMyOtherInterface { get; }
}

..它运作良好＆＃39;就像在 - datacontractserializer确实创建

<MyInterfaceImplementation>...</MyInterfaceImplementation>

...节点而不是z：anyType但是我不想/不能改变我的接口＆＃39;属性。在这种情况下，有没有办法控制或帮助数据合同序列化器？

DataContractSerializer将接口属性序列化为System.Object / anyType
