WebException Constructor (String, Exception)

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

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

public:
WebException(
	String^ message, 
	Exception^ innerException
)

Parameters

message
Type: System::String

The text of the error message.

innerException
Type: System::Exception

A nested exception.

The WebException instance is initialized with the Message property set to the value of message and the InnerException property set to the value of innerException. If message is nullptr, the Message property is initialized to a system-supplied message. The InnerException and Response properties are initialized to nullptr. The Status property is initialized to RequestCanceled.

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

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

   // The IPaddress of the unknown uri is resolved using the 'Dns::Resolve' method.

   IPHostEntry^ hostEntry = Dns::Resolve( connectUri );

   IPAddress^ serverAddress = hostEntry->AddressList[ 0 ];
   IPEndPoint^ endPoint = gcnew IPEndPoint( serverAddress, 80 );
   httpSocket->Connect( endPoint );
   Console::WriteLine( "Connection created successfully" );
   httpSocket->Close();
}
catch ( SocketException^ e ) 
{
   Console::WriteLine( "\nException thrown.\nThe Original Message is: {0}", e->Message );
   //  Throw the 'WebException' object with a message string specific to the situation; 
   //  and the 'InnerException' that actually led to this exception. 
   throw gcnew WebException( "Unable to locate the Server with 'www.contoso.com' Uri.", e );
}
