XML文件设置树形结构(无限级)-原创

 

在写Windows环境下,常会用到Tree控件,以下是通过XML文件构建Tree控件树形的方法.

添加一个引用

using System.XML.Linq;

public static void LoadTree(TreeView tv)
        {
            tv.Nodes.Clear();
            XDocument doc = XDocument.Load(SaveData.xmlPath);
            IEnumerable<XElement> q = from p in doc.Element("nodeList").Elements("node")
                    select p;
            
            foreach (var n in q)
            {
                TreeNode node=new TreeNode();
                string name=n.Attribute("name").Value;
                node.Text =name;
                tv.Nodes.Add(node);
                childTree(node, q.Where(c => c.Attribute("name").Value == name));
            }
        }

        private static void childTree(TreeNode node, IEnumerable<XElement> x)
        {
            var q = from p in x.Elements("childNode")
                    select p;
            foreach (var n in q)
            {
                TreeNode tn = new TreeNode();
                string name = n.Attribute("name").Value;
                tn.Text = name;
                node.Nodes.Add(tn);
                childTree(tn, q.Where(c => c.Attribute("name").Value == name));

            }
        }
