Question

我有这个例子，但我想知道如何管理这个例子的超时。请帮我。提前致谢

public void callREST()
{

Uri uri = new Uri("http://www.domain.com/RestService"); 
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri);
request.Method = "POST";
request.ContentType = "application/xml";    

request.BeginGetRequestStream(sendXML_RequestCallback, request);                  

}

private void sendXML_RequestCallback(IAsyncResult result)
{
    var req = result.AsyncState as HttpWebRequest;

    byte[] toSign = Encoding.GetEncoding("ISO-8859-1").GetBytes("<xml></xml>");

    using (var strm = req.EndGetRequestStream(result))
    {
        strm.Write(toSign, 0, toSign.Length);
        strm.Flush();
    }
req.BeginGetResponse(this.fCallback, req);
}

private void fCallback(IAsyncResult result)
{
     var req = result.AsyncState as HttpWebRequest;                
     var resp = req.EndGetResponse(result);
     var strm = resp.GetResponseStream();
     //Do something
}

Silverlight / Windows Phone 7中的HttpWebRequest不支持

Timeout。

您需要创建Timer并在启动请求的同时启动它。如果计时器在HWR返回之前触发，则Abort()请求并假设它超时。
