将XML文件绑定到TreeView，建立树形导航

      我在开发系统，特别是管理系统的时候，经常需要用到TreeView来作为导航的载体。现在将把XML文件绑定到TreeView的方法贴出，供大家指点。
       以下是XML代码：
      

 

 1<?xml version="1.0" encoding="utf-8" ?>
 2<ContentPage>
 3  <MenuTitle id="1" value="用户管理实例一">
 4    <ContentPageRecord>
 5      <ContentCode>11</ContentCode>
 6      <ContentTitle>新增新闻</ContentTitle>
 7      <ContentPath>URL</ContentPath>
 8    </ContentPageRecord>
 9    <ContentPageRecord>
10      <ContentCode>12</ContentCode>
11      <ContentTitle>更新新闻</ContentTitle>
12      <ContentPath>URL</ContentPath>
13    </ContentPageRecord>
14    <ContentPageRecord>
15      <ContentCode>13</ContentCode>
16      <ContentTitle>删除新闻</ContentTitle>
17      <ContentPath>URL</ContentPath>
18    </ContentPageRecord>
19  </MenuTitle>
20
21  <MenuTitle id="2" value="用户管理实例二">
22    <ContentPageRecord>
23      <ContentCode>21</ContentCode>
24      <ContentTitle>新增用户</ContentTitle>
25      <ContentPath>URL</ContentPath>
26    </ContentPageRecord>
27    <ContentPageRecord>
28      <ContentCode>22</ContentCode>
29      <ContentTitle>更新用户</ContentTitle>
30      <ContentPath>URL</ContentPath>
31    </ContentPageRecord>
32    <ContentPageRecord>
33      <ContentCode>23</ContentCode>
34      <ContentTitle>删除用户</ContentTitle>
35      <ContentPath>URL</ContentPath>
36    </ContentPageRecord>
37
38  </MenuTitle>
39</ContentPage>
40

下面则是绑定方法：

 1  protected void DataBindTreeView()
 2        {
 3            DataSet ds = new DataSet();
 4            ds.ReadXml(Server.MapPath(@"MoviesList.xml"));
 5            if (ds != null)
 6            {
 7                foreach (DataRow function in ds.Tables[0].Rows)
 8                {
 9                    if (string.IsNullOrEmpty(function["Value"].ToString())) continue;
10                    TreeNode Root = new TreeNode();
11                    Root.Text = function["Value"].ToString();
12                    Root.Value = function["id"].ToString();
13                    Root.Expanded = false;
14
15                    DataRow[] childrows = ds.Tables[1].Select("MenuTitle_Id=" + function["MenuTitle_Id"]);
16                    if (childrows.Length > 0)
17                    {
18                        foreach (DataRow chRow in childrows)
19                        {
20                            if (string.IsNullOrEmpty(chRow["ContentTitle"].ToString())) continue;
21                            string selectedNode = Session["System_Selected_Node"] as string;
22                            if (selectedNode == chRow["ContentTitle"].ToString())
23                                Root.Expanded = true;
24
25                            TreeNode temp = new TreeNode();
26                            temp.Text = chRow["ContentTitle"].ToString();
27                            temp.Value = chRow["ContentCode"].ToString();
28                            temp.NavigateUrl = chRow["ContentPath"].ToString();
29                            Root.ChildNodes.Add(temp);
30                        }
31                    }
32                    TreeView1.Nodes.Add(Root);
33                }
34            }
35        }

以上仅供参考。 多谢指点！
