Question

I want to create an array/list of strings of the Comma seperated strings (file extensions) that are entered in a Textbox.

For the following block of code:

            Dim csv As String = Textbox1.Text + ','              While csv.IndexOf('.') <> -1                 lstOfStrings.Add(csv.Substring(0, csv.IndexOf(',')))                 csv = csv.Remove(0, csv.IndexOf(',') + 1)             End While 

The output is:

Textbox1.Text = ‘.exe,.php’

listOfStrings = { ‘.exe’, ‘.php’ }

Is there a better way to write this code?

Answer 1

A better way would be to use the Split method:

Dim lstOfStrings() As String = Textbox1.Text.Split(','c)
