Exception handling isa
technique of handling a situation which is occur at the run time when
program
abort without execution and the cause of that situation is called
exception.
Exception can be
handled by
two ways in VB.NET .
1.Structured exception handling.
2. Unstructured exception handling.
Hear I am going to
tell about
the structured exception handling using : Try….Catch….Finally.
Example:
Module Module1
Sub Main()
Dim a = 0, b = 1, c
As Integer
Try
c = b / a
Console.WriteLine("C
is " & c)
Catch e As Exception
Console.WriteLine(e)
Console.WriteLine("0
can't be divided by any number")
Console.ReadLine()
End Try
End Sub
End Module
OUTPUT:

In this code a numberis
divided by zero which result is infinity. This error is thrown by Try
Block and
Catch block shows the exception after catching it.
CONCLUSION:
This example helps you to understand how exception occurs than thrown
and than
catch and shows the exception at the run time.
