public static IWebProxy Select { get; set; }

Property Value

Type: System.Net.IWebProxy

An IWebProxy that every call to HttpWebRequest.GetResponse uses.

Exception Condition
ArgumentNullException

The value specified for a set operation was null.

SecurityException

The caller does not have permission for the requested operation.

The Select property sets the proxy that all WebRequest instances use if the request supports proxies and no proxy is set explicitly using the Proxy property. Proxies are currently supported by FtpWebRequest and HttpWebRequest.

The following code example sets the Select property to the empty proxy.

using System;
using System.Net;
using System.IO;
namespace Examples.Http
{
    public class TestGlobalProxySelection
    {
        public static void Main()
        {
            // Create a request for the Web page at www.contoso.com.
            WebRequest request = WebRequest.Create("http://www.contoso.com");
            // This application doesn't want the proxy to be used so it sets 
            // the global proxy to an empty proxy.
            IWebProxy myProxy = GlobalProxySelection.GetEmptyWebProxy();
            GlobalProxySelection.Select = myProxy;
            // Get the response.
            WebResponse response = request.GetResponse();
            // Display the response to the console.
            Stream stream = response.GetResponseStream();
            StreamReader reader = new StreamReader(stream);
            Console.WriteLine(reader.ReadToEnd());
            // Clean up.
            reader.Close();
            stream.Close();
            response.Close();
        }
    }
}
