修剪VB.NET中字符串的最后一个","分隔符

Question

这是我的代码:

With ad.Tables(2)
    For i As Integer = 0 To .Rows.Count - 1
        If .Rows(i)("name") & "" <> "" Then
            temp &= .Rows(i)("name") & ", "
        End If
    Next
End With
temp = temp.Trim(",")
testing &= "&Name=" & temp & vbCrLf

这是在字符串的末尾得到一个逗号.但如果我这样做

temp = temp.Trim.Trim(",")

所有逗号都被删除.

如何保留所有逗号并仅删除最后一个逗号？

Answer 1

temp = temp.Trim().Substring(0, temp.Length - 1)

要么

temp = temp.Trim().Remove(temp.Length - 1)

Answer 2

temp = temp.TrimEnd(CChar(","))

这样做,我认为是最简单的方法.
