WebProxy()

Source:: WebProxy.cs

Source:: WebProxy.cs

Source:: WebProxy.cs

Initializes an empty instance of the WebProxy class.

public:
 WebProxy();

public WebProxy ();

Public Sub New ()

Examples

The following code example demonstrates calling this constructor.

WebProxy^ CreateProxy()
{
   return gcnew WebProxy;
}

public static WebProxy CreateProxy()
{
    return new WebProxy();
}

Remarks

The parameterless constructor initializes an empty instance of the WebProxy class with the Address property set to null.

When the Address property is null, the IsBypassed method returns true and the GetProxy method returns the destination address.
