Please Check this:
Dim Mystring As String = "This is a test This is a test This is a test This is a test This is a test This is a test This is a test This is a test This is a test This is a test This is a test This is a test This is a test This is a test This is a test This is a test This is a test This is a test This is a test This is a test This is a test This is a test"
        Dim arr As New List(Of String)
        Dim sw As New StreamWriter("C:\SampleOutput.txt")
        Dim num As Integer = 0
        For i As Integer = 0 To Mystring.Length - 44 Step 44
            num = num + 1
            arr.Add(Mystring.Substring(i, 44) & " - " & " Line " & num)
        Next
        Dim joinedString As String = String.Join(vbCrLf, arr.ToArray)
        sw.Write(joinedString)
        sw.Close()

Hi!

I didn't see that you requirement need another condition that MyString should be "The max of string is 2058".

So check this as well.
Dim Mystring As String = "This is a test This is a test This is a test This is a test This is a test This is a test This is a test This is a test This is a test This is a test This is a test This is a test This is a test This is a test This is a test This is a test This is a test This is a test This is a test This is a test This is a test This is a test"
Dim arr As New List(Of String)
Dim sw As New StreamWriter("C:\SampleOutput.txt")
Dim num As Integer = 0
If Mystring.Length <= 2058 Then
   For i As Integer = 0 To Mystring.Length - 44 Step 44
      num = num + 1
      arr.Add(Mystring.Substring(i, 44) & " - " & " Line " & num)
   Next
Dim joinedString As String = String.Join(vbCrLf, arr.ToArray)
sw.Write(joinedString)
sw.Close()
End If
