How to check whether the string is numeric or not in

In Vb.Net it is very easy to check any string whether it can convert to an integer or not with the help of IsNumeric function.
you can use this function like this:
IsNumeric(Expression As Object) as Boolean

You can pass any value within the function and it will return true if Expression can convert in Integer and false if it cannot.


Private Function CheckNumeric(ByVal Expression As Object) As Boolean
        If IsNumeric(Expression) Then
            CheckNumeric = True
            CheckNumeric = False
        End If
End Function

If we pass in function “222” then it will return true and if we pass “abcd” then it will return false
