How To Split A String Into A Fixed Length String Array?

- 1 answer

I have a long string like this

dim LongString as String = "123abc456def789ghi"

And I want to split it into a string array. Each element of the array should be in 3 characters length

For example,

Dim LongArray(5) As String
LongArray(0)  = "123"
LongArray(1)  = "abc"
LongArray(2)  = "456"
LongArray(3)  = "def"
LongArray(4)  = "789"
LongArray(5)  = "ghi"

How do I split it using VB.net code?

This could work.

 Module Module1

    Sub Main()
        Dim LongString As String = "123abc456def789ghi"
        Dim longlist As New List(Of String)
        For i As Integer = 0 To Convert.ToInt32(LongString.Length / 3) - 1
            longlist.Add(LongString.Substring(i * 3, 3))
        Next
        For Each s As String In longlist
            Console.WriteLine(s)
        Next
        Console.ReadLine()
    End Sub

End Module

And this should work in .Net 1.1

Module Module1

    Sub Main()
        Dim LongString As String = "123abc456def789ghi"
        Dim longlist(Convert.ToInt32(LongString.Length / 3) - 1) As String
        For i As Integer = 0 To Convert.ToInt32(LongString.Length / 3) - 1
            longlist(i) = (LongString.Substring(i * 3, 3))
        Next
        For i As Integer = 0 To Convert.ToInt32(LongString.Length / 3) - 1
            Console.WriteLine(longlist(i))
        Next
        Console.ReadLine()
    End Sub

End Module
