我想一个客户端的数据下载到我的本地计算机（编程）和他们的网络服务器是非常，这是造成我的 Web客户端对象超时很慢。

I am trying to download a client's data to my local machine (programatically) and their webserver is very, very slow which is causing a timeout in my WebClient object.

下面是我的code：

WebClient webClient = new WebClient();

webClient.Encoding = Encoding.UTF8;
webClient.DownloadFile(downloadUrl, downloadFile);

有没有一种方法来设置这个对象上的无限超时？或者，如果没有谁能帮我用一个例子上的另一种方法来做到这一点？

Is there a way to set an infinite timeout on this object? Or if not can anyone help me with an example on an alternate way to do this?

推荐答案

您可以延长超时：继承了原WebClient类，并重写的WebRequest吸气设置自己的超时时间，就像下面的例子。 MyWebClient是一个私有类在我的情况

You can extend the timeout: inherit the original WebClient class and override the webrequest getter to set your own timeout, like in the following example. MyWebClient was a private class in my case

  private class MyWebClient : WebClient
    {
        protected override WebRequest GetWebRequest(Uri uri)
        {
            WebRequest w = base.GetWebRequest(uri);
            w.Timeout = 20 * 60 * 1000;
            return w;
        }
    }
