vb.net 拆分字符串的最后一部分

Question

net 2.0 并且需要拆分字符串的最后一个/标记。目前我有一个代码，上面写着 Dim test As String = "Software\Microsoft\Windows\Welcome"并需要一个代码，将 Software\Microsoft\Windows\Welcome 最后分成两个单独的部分
所以我将 Software\Microsoft\Windows 和 Welcome 作为新字符串。
我只能找到将开始与其余部分分开的东西，例如

Dim whole As String = "Software/Microsoft/Windows/Run"
Dim firstpart As String = whole.Substring(0, whole.IndexOf("/"))
Dim lastpart As String = whole.Substring(whole.IndexOf("/") + 1)`

Answer 1

使用 String.LastIndexOf()

Dim whole As String = "Software/Microsoft/Windows/Run"
Dim firstpart As String = whole.Substring(0, whole.LastIndexOf("/"))
Dim lastpart As String = whole.Substring(whole.LastIndexOf("/") + 1)
