使用c＃从代理服务器下载文件

Question

I want to download file using a proxy connection. My example code is:

        WebClient client = new WebClient();
        WebProxy wp = new WebProxy("url_proxy_server");
        //wp.Credentials = new NetworkCredential("id", "pass", "domain");
        client.Proxy = wp;
        client.DownloadFile("http:mylink", "Save Path");

Is this a correct mode to download? How i can set port number?

Answer 1

Using the other constructor (String, Int32)

WebProxy wp = new WebProxy("http://contoso", 80);

Answer 2

您还可以在代理URL中指定端口

WebProxy wp = new WebProxy("url_proxy_server:proxyPort");
