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

Accepted Answer

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);
```
