我手动编写Web.sitemap文件，里面写了一个简单的网络书城的站点地图:
<?xml version="1.0" encoding="utf-8" ?>
<siteMap xmlns="http://schemas.microsoft.com/AspNet/SiteMap-File-1.0" >
<siteMapNode url="index.aspx" title="网络书城" description="网络书城">
<siteMapNode url="~/Sample1/text1.aspx" title="文学" description="文学" >
<siteMapNode url="~/Sample1/text2.aspx" title="小说" description="小说" />
<siteMapNode url="~/Sample1/text3.aspx" title="散文" description="散文" />
</siteMapNode>
<siteMapNode url="~/Sample2/text4.aspx" title="工学" description="杂学">
<siteMapNode url="~/Sample2/text5.aspx" title="计算机学" description="计算机" />
<siteMapNode url="~/Sample2/text6.aspx" title="机械学" description="机械学" />
</siteMapNode>
</siteMapNode>
</siteMap>然后创建一个网页index.aspx；在页面添加SiteMapDataSource控件，ID为SiteMapDataSource1；在页面添加TreeView，ID为TreeView1，设置TreeView1属性DataSourceID为SiteMapDataSource1，代码如下：
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="index.aspx.cs" Inherits="TreeView控件.index" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>无标题页</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:SiteMapDataSource ID="SiteMapDataSource1" runat="server" />
</div>
<asp:TreeView ID="TreeView1" runat="server" DataSourceID="SiteMapDataSource1">
</asp:TreeView>
</form>
</body>
</html>调试运行时报错说XmlSiteMapProvider 所需的文件 web.sitemap 不存在。难道SiteMapDataSource控件不能自动感应绑定Web.sitemap文件中的内容，需要自己创建新的数据源XmlSiteMapProvider 吗？求高手指点。
