WebException.WebException(String, WebExceptionStatus) Constructor

Initializes a new instance of the WebException class with the specified error message and status.

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

public WebException (
	string message,
	WebExceptionStatus status
)
public WebException (
	String message, 
	WebExceptionStatus status
)
public function WebException (
	message : String, 
	status : WebExceptionStatus
)
Not applicable.

Parameters

message

The text of the error message.

status

One of the WebExceptionStatus values.

The WebException instance is initialized with the Message property set to the value of message and the Status property set to the value of status. If message is a null reference (Nothing in Visual Basic), the Message property is initialized to a system-supplied message. The InnerException and Response properties are initialized to a null reference (Nothing in Visual Basic).

The following example throws a WebException by specifying an error message and a WebExceptionStatus.


 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)
  {
      Console.WriteLine("\nException thrown.\nThe Original Message is: "+e.Message);
      // Throw the 'WebException' object with a message string and message status specific to the situation.
      throw new WebException("Unable to locate the Server with 'www.contoso.com' Uri.",WebExceptionStatus.NameResolutionFailure);
  }

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 = (IPAddress)hostEntry.get_AddressList().
        get_Item(0);
    IPEndPoint endPoint = new IPEndPoint(serverAddress, 80);
    httpSocket.Connect(endPoint);
    Console.WriteLine("Connection created successfully");
    httpSocket.Close();
}
catch (SocketException e) {
    Console.WriteLine("\nException thrown.\nThe Original Message is: " 
        + e.get_Message());
    // Throw the 'WebException' object with a message string and message
    // status specific to the situation.
    throw new WebException("Unable to locate the Server with" 
        + " 'www.contoso.com' Uri.", WebExceptionStatus.
        NameResolutionFailure);
