Create a dynamic array

Here, we will create an array and then redefine the size of the array using the "Redim" keyboard and assign more elements to the array.

Program/Source Code:

The source code to demonstrate the use of a dynamic array is given below. The given program is compiled and executed successfully.

VB.Net code to create a dynamic array

'VB.Net program to demonstrate the use of the dynamic array.

Module Module1

    Sub Main()
        Dim intArray() As Integer
        ReDim intArray(5)

        intArray(0) = 10
        intArray(1) = 20
        intArray(2) = 30
        intArray(3) = 40
        intArray(4) = 50

        ReDim Preserve intArray(10)
        intArray(5) = 60
        intArray(6) = 70
        intArray(7) = 80
        intArray(8) = 90
        intArray(9) = 100

        Console.WriteLine("Array elements are: ")
        For i = 0 To 9
            Console.Write("{0} ", intArray(i))
        Next i
        Console.WriteLine()
    End Sub

End Module

Output

Array elements are:
10 20 30 40 50 60 70 80 90 100
Press any key to continue . . . Array elements are:
10 20 30 40 50 60 70 80 90 100
Press any key to continue . . .

Explanation

In the above program, we created a module Module1 that contains a function Main(). In the Main(), we created an array intArr of 5 elements and then we assigned the 5 elements to the array. After that, we redefined the size of the array using the ReDim and Preserve keyboard and then assigned some more elements to the array, and then print all elements of the array on the console screen.
