ASP.NET反向循环

Question

我有一些代码，我正在尝试反向进行For循环，但似乎无法正常工作

Session("mysession") = "1234-5678-"

Dim delimiters As Char() = New Char() {"-"C}

Dim mystring As String() = Trim(Session("mysession")).Split(delimiters, StringSplitOptions.RemoveEmptyEntries)

For x = 0 to mystring.Length - 1 

    'Do Something

Next

这有效，但是以错误的顺序显示它我试图通过简单地执行此操作来反转它

For mystring.Length - 1 to x = 0 

但我收到了错误

Expression is a value and therefore cannot be the target of an assignment.

有什么想法吗？

反向循环的语法不正确。它应该是：

For x = mystring.Length - 1 To 0 Step -1
