WinForm递归绑定TreeView

 ///
 /// 所有地区泛型对象

 IList areaList = new List();
         private void BindArea(string cityNo,TreeNodeCollection nodes, int level)
 {
     List list = new List();
     foreach (AreaTInfo ai in areaList)
     {
         if (ai.F_AreaSN==cityNo)
         {
             list.Add(ai);
         }
     }
     level = level + 1;
     foreach (AreaTInfo item in list)
     {
         TreeNode tnc = new TreeNode();
         tnc.Text = item.AreaName;
         tnc.Tag = item.AreaSN;
         BindArea(item.AreaSN,tnc.Nodes, level);
         nodes.Add(tnc);
     }
 }

 

 

调用方法：

 

            areaList = _proxy.GetAreaInfo().ToList() ;

            BindArea("410000",this.treeView1.Nodes, 0);

            treeView1.ExpandAll();     /*这句是展开所有节点*/
