我想创建一个动态 Web.Sitemap，动态是指该文件应该是可编辑的，并且我希望能够从我的代码中编辑它的节点。我已经在按钮的点击事件上尝试过这个。

SiteMapNode smRoot = SiteMap.RootNode;
SiteMapNode smNode = new 
           SiteMapNode(smRoot.Provider, "Key", "~/Default.aspx", "Default");
smRoot.ChildNodes.Add(smNode);

但在最后一行出现错误Collection is read-only.。

我怎样才能做到这一点？

尝试这个...

public void GetSiteMap(List<string> MyList)
{
    /// Add namespace:
    ///using System.Xml;
    ///using System.Data;
    ///using System.Xml.Serialization;

    String MyHome = "http://www.mysite.com" ;//Create Absolute url start.

    // create DataSet and DataTable if needed, or use List Array only
   /*
        DataTable DT = new DataTable();
        foreach (var array in MyList)
        {
            DT.Rows.Add(array);
        }

    */
    XmlDocument doc = new XmlDocument();// create XML Documents
    XmlDeclaration dec = doc.CreateXmlDeclaration("1.0", null, null);// Create the head element
    doc.AppendChild(dec);

    XmlElement root = doc.CreateElement("urlset");// Create the root element with attributes

    root.SetAttribute("xmlns:xsi", "http://www.w3.org/2001/XMLSchema-instance");
    root.SetAttribute("xmlns:xsd", "http://www.w3.org/2001/XMLSchema");
    root.SetAttribute("xmlns", "http://www.sitemaps.org/schemas/sitemap/0.9");
    doc.AppendChild(root);

    //foreach (DataRow DR in DT.Rows)// if use DataTable or
    foreach (var array in MyList)// if use List only
    {
        XmlElement MyUrl = doc.CreateElement("url");//create child node for root node

        XmlElement Loc = doc.CreateElement("loc");//create child node for MyUrl node
        XmlElement Freq = doc.CreateElement("changefreq");//create child node for MyUrl node
        XmlElement Pri = doc.CreateElement("priority");//create child node for MyUrl node

        Loc.InnerText = MyHome + "/" + array;//set value for 1. child node  Loc node
        Freq.InnerText = "daily";//set value for 1. child node-Freq node
        Pri.InnerText = "0.85";//set value for 1. child node-Pri node

        MyUrl.AppendChild(Loc); //add child Loc node to MyUrl node
        MyUrl.AppendChild(Freq);//add child Freq node to MyUrl node
        MyUrl.AppendChild(Pri);//add child Pri node to MyUrl node


        root.AppendChild(MyUrl);//add child MyUrl node to root node
    }


    Response.Clear();
    XmlSerializer xs = new XmlSerializer(typeof(XmlDocument));
    Response.ContentType = "text/xml";
    xs.Serialize(Response.Output, doc);
    Response.End();
}

在 PageLoad() 上调用这个 void
