WebException Constructor

Initializes a new instance of the WebException class.

Namespace:  System.Net
Assemblies:   System.Net.Requests (in System.Net.Requests.dll)
  System (in System.dll)

public WebException()

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 null. The Status property is initialized to RequestCanceled.

The following example throws a default WebException.


	      try   
	      {
		      // A 'Socket' object has been created.
		      Socket httpSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

		      // The IPaddress of the unknown uri is resolved using the 'Dns.Resolve' method. 
		      
		      IPHostEntry hostEntry = Dns.Resolve("http://www.contoso.com");

		      IPAddress serverAddress = hostEntry.AddressList[0];
		      IPEndPoint endPoint = new IPEndPoint(serverAddress, 80);
		      httpSocket.Connect(endPoint);
		      Console.WriteLine("Connection created successfully");
		      httpSocket.Close();
		   }
         catch(SocketException e)
		   {
   		   String exp = e.Message;	
	   	   // Throw the WebException with no parameters. 
		      throw new WebException();
		   }
