List(of String) or Array or ArrayList

Question

Hopefully a simple question to most programmers with some experience.

What is the datatype that lets me do this?

Dim lstOfStrings as *IDK*

Dim Stri         


        

Answer 1

List(Of String) will handle that, mostly - though you need to either use AddRange to add a collection of items, or Add to add one at a time:

lstOfString.Add(String1)
lstOfString.Add(String2)
lstOfString.Add(String3)
lstOfString.Add(String4)

If you're adding known values, as you show, a good option is to use something like:

Dim inputs() As String = { "some value", _
                              "some value2", _
                              "some value3", _
                              "some value4" }

Dim lstOfString as List(Of String) = new List(Of String)(inputs)

' ...
Dim s3 = lstOfStrings(3)

This will still allow you to add items later as desired, but also get your initial values in quickly.

Edit:

In your code, you need to fix the declaration. Change:

Dim lstWriteBits() As List(Of String) 

To:

Dim lstWriteBits As List(Of String) 

Currently, you're declaring an Array of List(Of String) objects.
