C# 使用C将记录添加到关系XML

我有一个XML和XSD，我想用Dataset向trck表添加一条记录，我也在编写代码，但需要trackListrow。。。 我怎么办

playListDS rec = new playListDS();
            if(File.Exists(Server.MapPath("~/playlist.xml")))
                rec.ReadXml(Server.MapPath("~/playlist.xml"));


            int id = int.Parse(rec.track.Rows[rec.track.Rows.Count - 1][0].ToString()) + 1;

            if (ViewState["Filename"] != null && ViewState["Cover"] != null)
            {
                playListDS.trackListRow row  = new playListDS.trackListRow();
                  rec.track.AddtrackRow(id.ToString(), "mp3/" + ViewState["Filename"].ToString(), txtartist.Text,
                  txtalbum.Text, txttitle.Text,
                  txtannotation.Text, txtduration.Text, "mp3/cover" + ViewState["Cover"].ToString(),
                  txtinfo.Text, txtlink.Text);

你的意思是这样的：

playListDS rec = new playListDS();
if(File.Exists(Server.MapPath("~/playlist.xml")))
{
    rec.ReadXml(Server.MapPath("~/playlist.xml"));
}

int id = int.Parse(rec.track.Rows[rec.track.Rows.Count - 1][0].ToString()) + 1;

if (ViewState["Filename"] != null && ViewState["Cover"] != null)
{
    playListDS.trackListRow row = rec.track.AddtrackRow(id.ToString(), "mp3/" +
                              ViewState["Filename"].ToString(), txtartist.Text,
                              txtalbum.Text, txttitle.Text,
                              txtannotation.Text, txtduration.Text, "mp3/cover" +
                              ViewState["Cover"].ToString(),
                              txtinfo.Text, txtlink.Text);
}

您所需要的只是新添加的行？如果是这样的话，您将从AddtrackRow方法中获得新行。

是的，但是这样操作xml。Dew mp3播放器看不到两个曲目列表表
