操作xml,将xml数据显示到treeview的C#代码

效果：

代码：

xmldocument xml = new xmldocument();
        private void form1_load(object sender, eventargs e)
        {
            createxml();
            treenode tn = new treenode("魔兽");
            treeview1.nodes.add(tn);
            xml.load(@"d:\xmlfile.xml");
            xmlnode nod = xml.documentelement;
            int i = 0;
            foreach (xmlnode xn in nod.childnodes)
            {
                treeview1.topnode.nodes.add(xn.attributes["two"].value);

                foreach (xmlnode xn2 in xn.childnodes)
                {
                    treeview1.topnode.nodes[i].nodes.add(xn2.innertext);
                }
                i++;
            }
        }
        public void createxml()
        {
            //创建xml文件
            xmldeclaration dec = xml.createxmldeclaration("1.0", "utf-8", null);
            xml.appendchild(dec);
            //添加树形字段
            xmlelement one = xml.createelement("one");
            xmlelement two = xml.createelement("two");
            xmlelement two1 = xml.createelement("two");
            xmlelement three = xml.createelement("three");
            xmlelement threedl = xml.createelement("three");
            xmlelement three1 = xml.createelement("three");
            xmlelement three10 = xml.createelement("three");
            //添加树形结构关系
            xml.appendchild(one);
            one.appendchild(two);
            one.appendchild(two1);
            two.appendchild(three);
            two.appendchild(threedl);
            two1.appendchild(three1);
            two1.appendchild(three10);
            //添加属性
            two.setattribute("two", "不死");
            two1.setattribute("two", "暗夜");
            //添加内容
            three.innertext = "dk";
            threedl.innertext = "dl";
            three1.innertext = "dh";
            three10.innertext = "wd";
            xml.save(@"d:\xmlfile.xml");
        }
