vb.net – 将字符串拆分为对

我怎样才能在VB中将字符串拆分成双字母？

例如：abcdefgh

分成：ab cd ef gh

解决方法

我会把帽子扔进戒指：

Dim test As String = "abcdefgh"
Dim results As New List(Of String)

For i As Integer = 0 To test.Length - 1 Step 2
  If i + 1 < test.Length Then
    results.Add(test.Substring(i,2))
  Else
    results.Add(test.Substring(i))
  End If
Next

MessageBox.Show(String.Join(" ",results.ToArray))
