Raise Custom Exception

Hi,

In VB.NET, how can I raise custom exceptions? I am trying to doing something like

Try
    ...
    If FileNotFound Then
        Raise exFileNotFound(strFilename)
    End If
...

I would then expect to see the error message "The file xxxstrFilenamexxx was not found."

Just use the "Throw" keyword:

Something like:

    If FileNotFound Then
        Throw New Exception("The file " & strFilename & " was not found.")
    End If

Just use the MsgBox to display a message when the file is not found:



If New FileInfo(strFilename).Exist Then
   ' do something
Else
   MsgBox("The File " & strFilename & " was not found!")
End If
