winfrom_权限设置_TreeView的相关问题

1.获取TreeView的值：

循环TreeView,获取checked每个节点的Text,串起来用逗号“，”隔开，保存到数据库。

  List<string> list = new List<string>();
             foreach (TreeNode treeNode in this.tv1.Nodes)
             {
                 bool @checked = treeNode.Checked;
                 if (@checked)
                 {
                     bool flag = treeNode.Nodes.Count != ;
                     if (flag)
                     {
                         foreach (TreeNode treeNode2 in treeNode.Nodes)
                         {
                             list.Add(treeNode.Text + "," + treeNode2.Text);
                         }
                     }
                     else
                     {
                         list.Add(treeNode.Text);
                     }
                 }
             }
             txtTypeRemarks.Text = string.Join(",", list.ToArray());

             model.Remarks = txtTypeRemarks.Text;

2.修改权限TreeView时：

获取数据库的权限数据，将字符串转数组，循环匹配TreeViewd 节点，相同的节点checked

                     ----Load事件-----
                     txtTypeRemarks.Text = list[].Remarks;
                         foreach (TreeNode tnSub in tv1.Nodes)
                         {
                             FindTreeView(tnSub);
                         }

  private void FindTreeView(TreeNode tn)
         {
             string[] strArray = txtTypeRemarks.Text.Split(','); //字符串转数组

             tn.Checked = false;
             string remark = string.Empty;
             string tv = string.Empty;
             for (int i = ; i < strArray.Length; i++)
             {
                 remark = strArray[i].ToString().Trim();
                 tv = tn.Name.Trim();
                 if (remark == tv)
                 {
                     tn.Checked = true;
                 }
             }

         }

3.用户登录后，权限效果显示：

用户登录成功后，从数据库获取该用户的权限详情，传到首界面，在点击某个模块时，匹配有权限这可以看到相应界面，否则弹出提示

   public static string UserPower{ get;set;}
         public string LoginUser { get; set; }

         private void FrmMainAdmin_Load(object sender, EventArgs e)
         {
              //从登录界面获取的权限详情字符串
             FrmMainAdmin.UserPower = this.LoginUser; 
 7
         }
 //菜单栏
 private void menu_SelectedIndexChanged(object sender, EventArgs e)
         {
             if (typeof(UIMenuBar).IsInstanceOfType(sender))
             {
                 UIMenuBar menuBar = (UIMenuBar)sender;
                 switch (menuBar.SelectedItem.TargetModule)
                 {
                     case "学习内容管理":
                         bool flag = !FrmMainAdmin.UserPower.Contains("学习内容管理");
                         if (flag)
                         {
                             MessageBox.Show("您没有“学习内容管理”权限!");
                         }
                         else
                         {
                             AddTabPagesByForm(new Frm学习内容管理());
                         }
                         break;
