#Disable and #Enable directives (Visual Basic)

  • Artikkeli

The #Disable and #Enable directives are Visual Basic source code compiler directives. They are used to disable and re-enable all or specific warnings for regions of code.

    Dim variable1    'warning BC42024: Unused local variable: 'variable1'.
#Disable Warning
    Dim variable2    'no warning
#Enable Warning
    Dim variable3    'warning BC42024: Unused local variable: 'variable3'.

' Suppress warning about no awaits in this method.
#Disable Warning BC42356
    Async Function TestAsync() As Task
        Console.WriteLine("testing")
    End Function
#Enable Warning BC42356

You can also disable and enable a comma-separated list of warning codes.
