我想通过json.net序列化这段代码:

public interface ITestInterface
{
    string Guid {get;set;}
}

public class TestClassThatImplementsTestInterface1
{
    public string Guid { get;set; }
}

public class TestClassThatImplementsTestInterface2
{
    public string Guid { get;set; }
}


public class ClassToSerializeViaJson
{
    public ClassToSerializeViaJson()
    {             
         this.CollectionToSerialize = new List<ITestInterface>();
         this.CollectionToSerialize.add( new TestClassThatImplementsTestInterface2() );
         this.CollectionToSerialize.add( new TestClassThatImplementsTestInterface2() );
    }
    List<ITestInterface> CollectionToSerialize { get;set; }
}

我想用json.net序列化/反序列化ClassToSerializeViaJson.序列化工作正常,但反序列化给了我这个错误:

Newtonsoft.Json.JsonSerializationException:无法创建ITestInterface类型的实例.Type是接口或抽象类,无法实例化.

那么我该如何反序列化List<ITestInterface>集合呢？
