如何序列化的接口，如IList的< T> [英] How to serialize an interface such as IList<T>

问题描述

可能重复：结果
的如何序列化一个IList< T> ;?

我希望序列化类（姑且称之为取值），其中包含的IList<类型的属性; T> ，其中 T 是我所定义的另一个类。我得到一个例外，当我试图序列化类取值的一个实例为XML。这是可以理解的的XmlSerializer 不知道用哪个具体的类。有没有一种方法，希望使用属性，指定序列化/反序列化实例时实例化哪个具体的类。我班取值实施创建列表℃的情况下，T> 类。下面是一些代码来说明我的例子：

I wish to serialize an class (let's call it S) that contains a property of the type IList<T> where T is another class which I have defined. I get an exception when I attempted to serialize an instance of class S to XML. This is understandable as the XmlSerializer doesn't know which concrete class to use. Is there a way, hopefully using attributes, to specify which concrete class to instantiate when serializing/deserializing an instance. My implementation of class S creates a instance of the List<T> class. Here is some code to illustrate my example:

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

[Serializable]
public class T { }

[Serializable]
public class S
{
    public IList<T> ListOfTs { get; set; }

    public S()
    {
        ListOfTs = new List<T>();
    }
}

public class Program
{
    public void Main()
    {
        S s = new S();
        s.ListOfTs.Add(new T());
        s.ListOfTs.Add(new T());
        XmlSerializer serializer = new XmlSerializer(typeof(S));
        serializer.Serialize(new StringWriter(), s);
    }
}

我希望有一个属性，我可以在上面放置在 ListOfTs 定义，以连载说，假设的实例名单< T> 序列化/反序列化时。

I'm hoping there's an attribute I can place above the ListOfTs definition that says to the serialize, "assume an instance of List<T> when serializing/deserializing".

推荐答案

更改

public IList<T> ListOfTs { get; set; }

到

to

public List<T> ListOfTs { get; set; }

然后，它会正常工作。

Then it will work.
