WebException Constructor

Initializes a new instance of the WebException class.

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

'Declaration
Public Sub New

The default constructor initializes a new instance of the WebException class. The Message property is initialized to a system-supplied message that describes the error. This message takes into account the current system culture. The InnerException and Response properties are initialized to Nothing. The Status property is initialized to RequestCanceled.

The following example throws a default WebException.


        Try
            ' A 'Socket' object has been created.
            Dim httpSocket As New Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp)

            ' The IPaddress of the unknown uri is resolved using the 'Dns.Resolve' method. 
	         ' which leads to the 'SocketException' exception. 

            Dim hostEntry As IPHostEntry = Dns.Resolve("http://www.contoso.com")

            Dim serverAddress As IPAddress = hostEntry.AddressList(0)
            Dim endPoint As New IPEndPoint(serverAddress, 80)
            httpSocket.Connect(endPoint)
            Console.WriteLine("Connection created successfully")
            httpSocket.Close()
        Catch e As SocketException
            Dim exp As [String] = e.Message
            ' Throw the WebException with no parameters.
            Throw New WebException()
        End Try
