How to set proxy settings for my application in .NET

Question

I have an application in C# which uses a service reference to send SMS through a web service. The user's internet connection needs to pass through a proxy server in order to reach the world.

So my question is how to tell .NET to call web service through the proxy? Or how to set proxy settings for internet connection of my application just like what you can do in YMahoo Messenger?

Also I want to let user to choose proxy settings.

I believe what you are looking for is defaultProxy in your config file.

Here's an example from the link:

<configuration>
  <system.net>
    <defaultProxy>
      <proxy
        usesystemdefault="true"
        proxyaddress="http://192.168.1.10:3128"
        bypassonlocal="true"
      />
      <bypasslist>
        <add address="[a-z]+\.contoso\.com" />
      </bypasslist>
    </defaultProxy>
  </system.net>
</configuration>

Please try below code hope this will help you

tring targetUrl = "http://www.google.com";
string proxyUrlFormat = "http://zend2.com/bro.php?u={0}&b=12&f=norefer";
string actualUrl = string.Format(proxyUrlFormat, HttpUtility.UrlEncode(targetUrl));

// Do something with the proxy-ed url
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(new Uri(actualUrl));
HttpWebResponse resp = req.GetResponse();

string content = null;
using(StreamReader sr = new StreamReader(resp.GetResponseStream()))
{
    content = sr.ReadToEnd();
}

Console.WriteLine(content);

I am not making the request in my own code. The code fro request is generated by the service reference addition. Additionally application is acapable of auto-update so I want to enable for whole the application. Most likely using System.Net.GlobalProxySelection class is a solution but is obsolote!

I am now using GlobalProxySelection class to apply user settings. However the user is siting behind a domain controller and needs to set username and pasword for proxy setings in order to access the Internet. How do I set username and password?
