自己写方法，实现字符串翻转

实现：

' 反转字符串    Public Function ReverseByString(ByVal original As String) As String        Dim strOri As New System.Text.StringBuilder(original)        Dim orgLen As Integer = (original.Length - 1)        For i As Integer = 0 To orgLen            strOri(i) = original(orgLen)            strOri(orgLen) = original(i)            orgLen = orgLen - 1        Next        Return strOri.ToString()    End Function

简单的实现，放在这里，备忘一下
