将字符串截取

string[] strlist = str.Split(','); 

 

遍历TreeNode父节点  [TreeView1.Nodes]  

foreach (TreeNode rhp in TreeView1.Nodes)
       {   

        遍历字符串每一项与TreeNode子父节点value对比，值相等该节点选中   
           foreach (string strguid in strlist)
           {
               if (rhp.Value == strguid.ToLower())
               {
                   rhp.Checked = true;
               }

               遍历TreeNode子节点[rhp.ChildNodes]  
               foreach (TreeNode rhp1 in rhp.ChildNodes)
               {
                   if (rhp1.Value == strguid.ToLower())
                   {
                       rhp1.Checked = true;
                   }
               }
           }
       }
