是否可以使用ASP.NET Sitemap生成Breadcrumbs？

Question

我希望我的ASP.NET站点有简单的菜单字符串aka Breadcrumbs.我创建了包含所有必需元素的Sitemap并注册到Web.config中.例如:

<siteMap>
    <siteMapNode url="Default.aspx" title="Home" >
        <siteMapNode url="hosting/Default.aspx" title="Hosting" />
        <siteMapNode url="software/Default.aspx" title="Software">
            <siteMapNode url="firefox/Default.aspx" title="Firefox">
                <siteMapNode url="Download.aspx" title="Download" />
                <siteMapNode url="Support.aspx" title="Support" />
            </siteMapNode>
        </siteMapNode>
    </siteMapNode>
</siteMap>

并在Masterpage上创建了一个控件.这是菜单生成代码:

protected void Control_Load(Object sender, EventArgs e)
{
    string path = String.Empty;
    StringCollection list = new StringCollection();

    foreach (string str in Request.Url.Segments)
    {
        path += str;
        string link = String.Format("<a href=\"{0}://{1}{2}\">{3}</a>", Request.Url.Scheme, Request.Url.Authority, path, this.names[str]);
        list.Add(link);
    }

    foreach (string str in list)
    {
        menu += String.Concat(str, SeparatorLine);
    }
    menu = menu.Remove(menu.LastIndexOf(SeparatorLine));
}

但它使用像{{"/","Home"},{"hosting /","Hosting"},{"software /","Software"}这样的StringDictionary ..}

如何使用Sitemap的查询而不是它？或者其他东西,不是Sitemap,而是事先发明的.

Answer 1

ASP.NET SiteMapPath控件

<asp:SiteMapPath ID="SiteMapPath1" Runat="server" />

Answer 2

您可以使用SiteMapPath控件(应该位于工具箱的"导航"类别中).查看此页面以获取教程.
