Is there anything like exception code? that i can know that on different languages operation system i can recognize the same exception?

I need to recognize ‘Acces to the COMn Port is denied’ and then do some action, is that possible? has this exception any specified type?

Answer 1

From the sounds of it you will be getting a System.UnauthorizedAccessException (this assumption has been made from Googling the error message and finding this forum). To handle this, you would need to use catch clauses in a try-catch statement that are specific to this exception type. So, in C# you would do something like:

try
{
    // ... Run some code that might cause the error in question ...
}
catch (System.UnauthorizedAccessException ex)
{
    // ... Run some code that handles the error in question ...
}
