This post by Brian Grinsteadexplains how you can do just that.
Brian Grinstead 的这篇文章解释了如何做到这一点。
For proxy support, you only need to pass a Proxysetting to HttpWebRequest. So, in the above example, you would change:
对于代理支持，您只需将Proxy设置传递给HttpWebRequest. 因此，在上面的示例中，您将更改：
HttpWebRequest request = WebRequest.Create(postUrl) as HttpWebRequest;
To:
到：
string MyProxyHostString = "192.168.1.200";
int MyProxyPort = 8080;
HttpWebRequest request = WebRequest.Create(postUrl) as HttpWebRequest;
request.Proxy = new WebProxy (MyProxyHostString, MyProxyPort);

If you need to configue a proxy then you can do so in the .config file:-
如果您需要配置代理，那么您可以在 .config 文件中进行：-
<system.net>
<defaultProxy enabled="true">
<proxy proxyaddress="http://myproxyserver:8080" bypassonlocal="True"/>
</defaultProxy>
</system.net>
See this questionon form data posting.
请参阅有关表单数据发布的此问题。

If the web request works fine in your localhost with default proxy and not working in your web server, then you have to set your company's approved proxy and also whitelist the URL you are connecting to from your web application in the web server.
如果 Web 请求在您的本地主机中使用默认代理正常运行，但在您的 Web 服务器中不起作用，那么您必须设置公司批准的代理，并将您从 Web 服务器中的 Web 应用程序连接到的 URL 列入白名单。
You can mention the proxy settings either in web.config or in code.
您可以在 web.config 或代码中提及代理设置。
<system.net>
<defaultProxy enabled="true">
<proxy proxyaddress="http://yourcompanyproxyserver:8080" bypassonlocal="True"/>
</defaultProxy>
</system.net>
(or)
（或者）
HttpWebRequest wr = (HttpWebRequest)WebRequest.Create("URL");
wr.Proxy = new WebProxy("companyProxy",Portnumber);
wr.Method = "POST";
