WCF 服务序列化:反序列化器不知道映射到此名称的任何类型 [英] WCF Service Serialization: The deserializer has no knowledge of any type that maps to this name

问题描述

我正在尝试构建 WCF 服务，但遇到了阻塞问题.我一直在谷歌搜索，但我一直无法取得任何进展.希望我在这里能有更多的好运.

I'm trying to build out a WCF service but I've run into a blocking issue. I've been Googling around but I haven't been able to make any progress. Hopefully I'll have more luck here.

假设我有一个这样定义的工作类别:

Let's say I have a job class defined as such:

[DataContract]
public class Job : IJob
{
    public Job(...)
    {
    }

    [DataMember]

    public string Example
    {
        get { return m_example; }
        set { m_example = value; }
    }
}

现在，我做的是这样的

public void DoSomething()
{
    ExampleServiceProxy.ExampleClient proxy = new ExampleServiceProxy.ExampleClient();
    proxy.DoSomething(job);
}

在我的 Reference.cs 中，我添加了一些 ServiceKnownTypeAttribute，如下所示:

Inside of my Reference.cs I've added some ServiceKnownTypeAttribute as follows:

...
[System.ServiceModel.ServiceKnownTypeAttribute(typeof(Job))]
void DoSomething(object job);

我的服务代码如下:

[ServiceContract]
public interface IExample
{
    [OperationContract]
    void DoSomething(IJob);
}

public class Example : IExample
{
    public void DoSomething(IJob job)
    {
        ...
    }
}

我需要在某处放置更多的 ServiceKnownTypeAttributes 吗?我需要在服务端重新实现对象吗?

Do I need to put further ServiceKnownTypeAttributes somewhere? Do I need to reimplement the object on the service side?

推荐答案

您必须将 ServiceKnownType 属性放在 Service Contract 接口上.

You have to put the ServiceKnownType attribute on the Service Contract interface.

[ServiceContract] 
public interface IExample 
{ 
    [OperationContract] 
    [ServiceKnownType(typeof(Job))]
    void DoSomething(IJob); 
} 

public class Example : IExample 
{ 
    public void DoSomething(IJob job) 
    { 
        ... 
    } 
}
