The browser control is just an instance of IE - it will use IE's proxy settings. You can set these by playing with registry keys if you must do it in code.

        string key = "Software\\Microsoft\\Windows\\CurrentVersion\\Internet Settings";
        string serverName = "";//your proxy server name;
        string port = ""; //your proxy port;
        string proxy = serverName + ":" + port;

        RegistryKey RegKey = Registry.CurrentUser.OpenSubKey(key, true);
        RegKey.SetValue("ProxyServer", proxy);
        RegKey.SetValue("ProxyEnable", 1);

Update: Looks like this can be done for just the control and not the entire machine. See this code sample for setting the proxy for just a single process - http://blogs.msdn.com/b/jpsanders/archive/2011/04/26/how-to-set-the-proxy-for-the-webbrowser-control-in-net.aspx
