发送多的WebRequest中的Parallel.For [英] Send multiple WebRequest in Parallel.For

问题描述

我想给多个的WebRequest 。我用了一个的Parallel.For 循环，这样做，但在循环运行一次，第二次提示错误而得到响应。

错误：

  

该操作已超时

code：

 的Parallel.For（0，10，委托（int i）以{
    HttpWebRequest的要求=（HttpWebRequest的）WebRequest.Create（
        新的URI（http://www.mysite.com/service））;    字符串dataToSend =数据;
    字节[]缓冲= System.Text.Encoding.GetEncoding（1252）。
        GetBytes会（dataToSend）;
    request.Method =POST;
    request.ContentType =应用/的X WWW的形式urlen codeD;
    request.ContentLength = buffer.Length;    request.Host =www.mysite.com;    流requestStream = request.GetRequestStream（）;
    requestStream.Write（缓冲液，0，buffer.Length）;
    requestStream.Close（）;    HttpWebResponse响应=（HttpWebResponse）request.GetResponse（）;
}）;
 

解决方案

最有可能的问题是，你需要调用 response.Close（）大功告成后，处理响应

I want to send multiple WebRequest. I used a Parallel.For loop to do that but the loop runs once and the second time it gives error while getting response.

Error:

The operation has timed out

Code :

Parallel.For(0, 10, delegate(int i) {
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(
        new Uri("http://www.mysite.com/service"));

    string dataToSend = "Data";
    byte[] buffer = System.Text.Encoding.GetEncoding(1252).
        GetBytes(dataToSend);
    request.Method = "POST";
    request.ContentType = "application/x-www-form-urlencoded";
    request.ContentLength = buffer.Length;

    request.Host = "www.mysite.com";

    Stream requestStream = request.GetRequestStream();
    requestStream.Write(buffer, 0, buffer.Length);
    requestStream.Close();

    HttpWebResponse response = (HttpWebResponse)request.GetResponse();
});

解决方案

Most likely the problem is that you need to call response.Close() after you're done processing the response.
