主题：Trim不起作用？？？

trim不起作用？？？通过Messagebox可以看出，怎么把都好全去掉呢？？？

Dim trv1 As WinForm.TreeView = e.Form.Controls("TreeView1")

Dim nd1 As WinForm.TreeNode = trv1.SelectedNode

Dim dr As DataRow = DataTables("Team_Users").find("Name = '"& nd1.Text & "'")

messagebox.show(nd1.Text)

Dim nms As String

Dim s As String

For i As Integer = 0 To 42

    s = DataTables("System_Permission_User").DataRows(i)("Permission")

    nms = nms & "," & s

Next

Messagebox.show(nms)

dr("PermissionValue") = nms.Trim(",")

MessageBox.show(dr("PermissionValue") )
