GlobalProxySelection::Select Property

Gets or sets the global HTTP proxy.

Namespace:  System.Net
Assembly:  System (in System.dll)

static property IWebProxy^ Select {
	IWebProxy^ get ();
	void set (IWebProxy^ value);

Property Value

Type: System.Net::IWebProxy
An IWebProxy that every call to HttpWebRequest::GetResponse uses.


The value specified for a set operation was nullptr.


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.dll>

using namespace System;
using namespace System::Net;
using namespace System::IO;
int main()

   // Create a request for the Web page at www.contoso.com.
   WebRequest^ request = WebRequest::Create( L"http://www.contoso.com" );

   // This application doesn't want they proxy to be used so it sets 
   // the global proxy to an empy proxy.
   IWebProxy^ myProxy = GlobalProxySelection::GetEmptyWebProxy();

   // Get the response.
   WebResponse^ response = request->GetResponse();

   // Display the response to the console.
   Stream^ stream = response->GetResponseStream();
   StreamReader^ reader = gcnew StreamReader( stream );
   Console::WriteLine( reader->ReadToEnd() );

   // Clean up.
   return 0;
