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 != 0;
                    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[0].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 = 0; 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;
