c# - 使用c#从代理服务器下载文件

Question

我想使用代理连接下载文件。我的示例代码是:

        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");

这是下载的正确模式吗？如何设置端口号？

Answer 1

使用另一个构造函数(String、Int32)

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