Silverlight 4 Ria服务超时问题 [英] Silverlight 4 Ria Services Timeout Issues

问题描述

我正在从Silverlight客户端向DomainService进行呼叫，通常需要大约2分钟。为了安全起见，我需要将端点的超时值延长到5分钟，但它似乎忽略了该设置，因此我找不到原因。这是我在客户端中创建DomainContext的方式：

I am making a call from my Silverlight client into my DomainService that normally takes about 2 minutes. I need to extend the timeout value of the endpoint to 5 minutes to be safe, but it appears to ignore the setting and I can't find out why. Here is how I am creating my DomainContext in my client:

MyDomainContext context = new MyDomainContext();
((WebDomainClient<MyDomainContext.IMyDomainServiceContract>)context.DomainClient).ChannelFactory.Endpoint.Binding.ReceiveTimeout = new TimeSpan(0, 5, 0);
context.Search(_myParms, p =>
    {
      if (p.HasError)
      {
        // Handle errors
      }

       // Should take about 2 min. to get here, but times out before          
     }, null);

我尝试同时设置ReveiveTimeout和SendTimeout，但是我总是在1分钟时收到错误消息。

I have tried setting the ReveiveTimeout and SendTimeout both, but I always get the error at exactly 1 minute.

有人可以告诉我我在做什么错吗？

Can someone tell me what I am doing wrong?

编辑：这是我得到的确切错误：

This is the exact error I am getting:

{System.Net.WebException：远程服务器返回错误：NotFound。 ---> System.Net.WebException：远程服务器返回错误：NotFound。 System.Net.Browser.BrowserHttpWebRequest.InternalEndGetResponse（IAsyncResult asyncResult）的
System.Net.Browser.BrowserHttpWebRequest的
。<> c_ DisplayClass5.b _4（对象sendState）
在System.Net.Browser.AsyncHelper。<> c_ DisplayClass2.b _0（Object sendState）
-内部异常堆栈跟踪的结尾-
在System.Net.Browser.AsyncHelper.BeginOnUI（SendOrPostCallback beginMethod，对象状态）
在System.Net.Browser.BrowserHttpWebRequest.EndGetResponse（IAsyncResult asyncResult）
在System.ServiceModel.Channels.HttpChannelFactory。 HttpRequestChannel.HttpChannelAsyncRequest.CompleteGetResponse（IAsyncResult result）}

{System.Net.WebException: The remote server returned an error: NotFound. ---> System.Net.WebException: The remote server returned an error: NotFound. at System.Net.Browser.BrowserHttpWebRequest.InternalEndGetResponse(IAsyncResult asyncResult) at System.Net.Browser.BrowserHttpWebRequest.<>c_DisplayClass5.b_4(Object sendState) at System.Net.Browser.AsyncHelper.<>c_DisplayClass2.b_0(Object sendState) --- End of inner exception stack trace --- at System.Net.Browser.AsyncHelper.BeginOnUI(SendOrPostCallback beginMethod, Object state) at System.Net.Browser.BrowserHttpWebRequest.EndGetResponse(IAsyncResult asyncResult) at System.ServiceModel.Channels.HttpChannelFactory.HttpRequestChannel.HttpChannelAsyncRequest.CompleteGetResponse(IAsyncResult result)}

我也进行了测试，以确保它不在我的服务中。目前，我只是让我的服务运行while循环。再次，我恰好在一分钟内收到此错误。

I have also tested to make sure it's not something in my service. At present, I just have my service run a while loop. Again, I get this error at exactly one minute.

谢谢，

推荐答案

您应该实现MyDomainContex类的部分方法OnCreated（）。

You should implement partial method OnCreated() of MyDomainContex class.

示例：

public partial class TestDomainContext
{
    partial void OnCreated()
    {
        var proxy = (WebDomainClient<Test.Server.Services.TestDomainContext.ITestDomainServiceContract>)this.DomainClient;
        proxy.ChannelFactory.Endpoint.Binding.SendTimeout = new TimeSpan(0, 5, 0);
    }
