WebProxy.GetProxy Method

Returns the proxied URI for a request.

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

public Uri GetProxy (
	Uri destination
public final Uri GetProxy (
	Uri destination
public final function GetProxy (
	destination : Uri
) : Uri
Not applicable.



The Uri instance of the requested Internet resource.

Return Value

The Uri instance of the Internet resource, if the resource is on the bypass list; otherwise, the Uri instance of the proxy.

The GetProxy method returns the URI that the WebRequest instance uses to access the Internet resource.

GetProxy compares destination with the contents of BypassList, using the IsBypassed method. If IsBypassed returns true, GetProxy returns destination and the WebRequest instance does not use the proxy server.

If destination is not in BypassList, the WebRequest instance uses the proxy server and the Address property is returned.

The following code example creates a WebProxy object and calls this method to get the proxy that is selected for a resource.

// The following method creates a WebProxy object that uses Internet Explorer's  
// detected script if it is found in the registry; otherwise, it 
// tries to use Web proxy auto-discovery to set the proxy used for
// the request.
public static void CheckAutoGlobalProxyForRequest(Uri resource)
    WebProxy proxy = new WebProxy();

    // Display the proxy's properties.

    // See what proxy is used for the resource.
    Uri resourceProxy = proxy.GetProxy(resource);

    // Test to see whether a proxy was selected.
    if (resourceProxy == resource)
        Console.WriteLine("No proxy for {0}", resource);
        Console.WriteLine("Proxy for {0} is {1}", resource.OriginalString,
