Question

How to find a value on an array by it’s index on VB.Net?

// INDEX:                       0    1    2    3    4
Dim DataArray(4) as Integer = {"A", "B", "C", "D", "E"}

Then, I randomize a number from 0 to 4. For example, when I got 3, then I will get D value on the array based on the randomize number. How can I do that? Thank you.

You can just access the value by having the index after the array name

Dim letter As String = DataArray(YourRandNumber)

Also there is a problem with your array, DataArray is declared as an integer array but storing alphabet, so you should change it to

Dim DataArray(5) As String = {"A", "B", "C", "D", "E"}

or

Dim DataArray(5) As Char= {"A"c, "B"c, "C"c, "D"c, "E"c}

The little c after “A” means it is a character
