WebProxy.GetDefaultProxy Method

Note: This API is now obsolete.

Reads the Internet Explorer nondynamic proxy settings.

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

'Declaration
<ObsoleteAttribute("This method has been deprecated. Please use the proxy selected for you by default. http://go.microsoft.com/fwlink/?linkid=14202")> _
Public Shared Function GetDefaultProxy As WebProxy

Return Value

Type: System.Net.WebProxy
A WebProxy instance that contains the nondynamic proxy settings from Internet Explorer 5.5 and later.

The GetDefaultProxy method reads the nondynamic proxy settings stored by Internet Explorer 5.5 and later, and creates a WebProxy instance with those settings.

The GetDefaultProxy method does not pick up any dynamic settings that are generated from scripts run by Internet Explorer, from automatic configuration entries, or from DHCP or DNS lookups.

Applications should use the WebRequest.DefaultWebProxy property and the WebRequest.GetSystemWebProxy method instead of the GetDefaultProxy method.

The following code example demonstrates calling this method.


Public Shared Sub CheckDefaultProxyForRequest(ByVal resource As Uri)
    Dim proxy As WebProxy = CType(WebProxy.GetDefaultProxy(), WebProxy)

    ' See what proxy is used for resource.
    Dim resourceProxy As Uri = proxy.GetProxy(resource)

    ' Test to see whether a proxy was selected.
    If resourceProxy = resource Then
        Console.WriteLine("No proxy for {0}", resource)
    Else
        Console.WriteLine("Proxy for {0} is {1}", resource.ToString(), resourceProxy.ToString())
    End If
End Sub
