Question

how to use http post with proxy support in c# and multipart form data upload method

Answer 1

If you need to configue a proxy then you can do so in the .config file:-

<system.net>
  <defaultProxy enabled="true">
    <proxy proxyaddress="http://myproxyserver:8080" bypassonlocal="True"/>
  </defaultProxy>
</system.net>

See this question on form data posting.

Answer 2

This post by Brian Grinstead explains how you can do just that.

For proxy support, you only need to pass a Proxy setting to HttpWebRequest. So, in the above example, you would change:

HttpWebRequest request = WebRequest.Create(postUrl) as HttpWebRequest;

To:

string MyProxyHostString = "192.168.1.200";
int MyProxyPort = 8080;

HttpWebRequest request = WebRequest.Create(postUrl) as HttpWebRequest;
request.Proxy = new WebProxy (MyProxyHostString, MyProxyPort);
