主题：[求助]请教,为什么目录树右侧的用户名没显示出来呢?

如题,键入以下代码后,右侧目录树的用户名没有显示出来,是什么原因呢?

Dim trv1 As WinForm.TreeView = e.Form.Controls("TreeView1")
Dim trv2 As WinForm.TreeView = e.Form.Controls("TreeView2")
trv1.BuildTree("授权表","分组|权限")
For Each u As UserInfo In Users
    If u.Type = UserTypeEnum.User Then 
        If trv2.Nodes.Contains(u.Group) = False Then
            trv2.Nodes.Add(u.Group)
        End If
        trv2.Nodes(u.Group).Nodes.Add(u.Name)
    End If
Next
Trv1.Nodes(0).Expand()
trv2.ExpandAll()

 右边，你要添加用户才有的。

这样写

Dim trv1 As WinForm.TreeView = e.Form.Controls("TreeView1")
Dim trv2 As WinForm.TreeView = e.Form.Controls("TreeView2")
trv1.BuildTree("授权表","分组|权限")
Trv1.Nodes(0).Expand()

trv1.BuildTree("用户表","分组|用户名")
trv2.ExpandAll()

Dim trv1 As WinForm.TreeView = e.Form.Controls("TreeView1")
Dim trv2 As WinForm.TreeView = e.Form.Controls("TreeView2")
trv1.BuildTree("授权表","分组|权限")
If Trv1.Nodes.Count > 0 Then Trv1.Nodes(0).Expand()

trv2.BuildTree("用户表","分组|用户名")
trv2.ExpandAll()
