Question

我正在尝试使用生成的代理从Silverlight调用WCF服务，并且出于某种原因我的参数被淘汰了。我这样打电话：

Events.EventServiceClient events = new Events.EventServiceClient(new BasicHttpBinding(),     new EndpointAddress("http://localhost:52878/EventService.svc"));
event.EventTypeName = e.GetType().FullName;
events.AddEventWrapperAsync(new EventWrapper(event));

在调试时，当我调用AddEventWrapperAsync方法时，我看到我有一个有效的对象。但是，进入下一个调用

public System.IAsyncResult BeginAddEventWrapper(BCL.BusinessObjects.EventWrapper Event, System.AsyncCallback callback, object asyncState) {
    object[] _args = new object[1];
    _args[0] = Event;
System.IAsyncResult _result = base.BeginInvoke("AddEventWrapper", _args, callback, asyncState);
    return _result;
}

我发现“Event”参数设置为新的EventWrapper（即，所有字段都设置为默认值）。

任何人都知道从哪里开始寻找？这显然是一个序列化问题，但除此之外，我感到困惑。

更新：这是EventWrapper

几个问题：

可能与问题无关但你为什么使用像“event”这样的保留关键字作为变量名呢？
您已调试服务器端并验证参数重整确实发生并且不仅仅是调试视图的问题，对吗？
是什么让您认为这是序列化问题？据我所知，尚未发生序列化。
您确定生成的代理/客户端代码与http://localhost:52878/EventService.svc

当前

更新：只是在黑暗中拍摄。使用Begin / End方法调用方法有什么不同吗？（我知道不应该）

更新1：您可以与我们分享BCL.BusinessObjects.EventWrapper的来源吗？

更新2： EventWrapper类的那些自定义构造函数对我来说很可疑，因为在客户端上，EventWrapper应该由Service Reference生成，因此不应包含这些构造函数。所以你在客户端上修改了Reference.cs - 你不应该做的事情，或者你以某种方式从服务器端代码中导入了代码 - 这是你不应该做的事情。哪一个？

Answer 2

您能否先使用WCFTestClient或SoapUI尝试使用Web服务？它可能是服务器端正在起作用。

另外，我更喜欢合同分享。这样就可以解决更少的问题，因为您不需要生成这些服务引用。

从Silverlight调用WCF服务：某处我的参数正在消失
