The following code example shows how to catch an InvalidEnumArgumentException exception and interpret its content. The example attempts to pass an invalid enumeration value (MessageBoxButtons) through casting, as the MessageBox.Show method's third argument. Upon catching the exception, the example fetches the respective error message, the invalid parameter, stack trace, and origin of the exception.

try
{
   //Attempting to pass an invalid enum value (MessageBoxButtons) to the Show method
   MessageBoxButtons myButton = (MessageBoxButtons)123; // to fix use System::Windows::Forms::DialogResult::OK;

   MessageBox::Show( this,  "This is a message",  "This is the Caption", myButton );
}
catch ( InvalidEnumArgumentException^ invE ) 
{
   Console::WriteLine( invE->Message );
   Console::WriteLine( invE->ParamName );
   Console::WriteLine( invE->StackTrace );
   Console::WriteLine( invE->Source );
}

try
{
    // Attempts to pass an invalid enum value (MessageBoxButtons) to the Show method
    MessageBoxButtons myButton = (MessageBoxButtons)123;
    MessageBox.Show("This is a message", "This is the Caption", myButton);
}
catch (InvalidEnumArgumentException invE)
{
    Console.WriteLine(invE.Message);
    Console.WriteLine(invE.ParamName);
    Console.WriteLine(invE.StackTrace);
    Console.WriteLine(invE.Source);
}

Try
    ' Attempts to pass an invalid enum value (MessageBoxButtons) to the Show method
    Dim myButton As MessageBoxButtons
    myButton = CType(123, MessageBoxButtons)
    MessageBox.Show("This is a message", "This is the Caption", myButton)
Catch invE As System.ComponentModel.InvalidEnumArgumentException
    Console.WriteLine(invE.Message)
    Console.WriteLine(invE.ParamName)
    Console.WriteLine(invE.StackTrace)
    Console.WriteLine(invE.Source)
End Try
