How to use Local global variable as Local variable without changing the name of variable in Vb.Net

All Variables are different in its scope and types on the basis of scope of the variable the variable can be describe as local either global.

The global variables can be accessed from anywhere inside the program but the local variable should be same name.

The local variables can be accessed only locally like in the class , sub or in a particular function and you cannot access these variables outside there local scope where you defined that variables.

To explain that how can you use a global variable as locally with the same name we take a example in this first we create a variable globally and than using that variable within two loops with the same name and shows the output of both loops using that single variable.

EXAMPLE

    Module Module1
        Dim series As Integer

        Sub cities()
            For series = 5 To 150
                Console.Write(series & " ")
            Next
        End Sub

        Sub countries()
            Dim series As Integer
            For series = 0 To 5
                Console.Write(series & " ")
            Next
        End Sub

        Sub Main()
            series = 5
            Console.WriteLine("Starting series: " & series)
            countries()
            Console.WriteLine("series after countries: " & series)
            cities()
            Console.WriteLine("series after cities: " & series)
            If (series > 150) Then
                Dim series As Integer = 0
                Console.WriteLine("series in If statement: " & series)
            End If
            Console.WriteLine("Ending series: " & series)
            Console.ReadLine()
        End Sub
    End Module

OUTPUT

CONCLUSION

I hope this article helps you to understand the working with variables locally and globally at the same time with same in the same module.
