You also can use multiple Catch statements when you filter exceptions. Here's an example that specifically handles overflow, invalid argument, and argument out of range exceptions:

Module Module1
    Sub Main()
        Dim int1 = 0, int2 = 1, int3 As Integer
        Try
            int3 = int2 / int1
            System.Console.WriteLine("The answer is {0}", int3)
        Catch e As System.OverflowException
            System.Console.WriteLine("Exception: Arithmetic overflow!")
        Catch e As System.ArgumentException
            System.Console.WriteLine("Exception: Invalid argument value!")
        Catch e As System.ArgumentOutOfRangeException
            System.Console.WriteLine("Exception: Argument out of range!")
        End Try
    End Sub
End Module

If you want to add a general exception handler to catch any exceptions not filtered, you can add a Catch block for the Exception class at the end of the other Catch blocks:

Module Module1
    Sub Main()
        Dim int1 = 0, int2 = 1, int3 As Integer
        Try
            int3 = int2 / int1
            System.Console.WriteLine("The answer is {0}", int3)
        Catch e As System.ArgumentOutOfRangeException
            System.Console.WriteLine("Exception: Argument out of range!")
        Catch e As System.ArgumentException
            System.Console.WriteLine("Exception: Invalid argument value!")
        Catch e As Exception
            System.Console.WriteLine("Exception occurred!")
        End Try
    End Sub
End Module
