web引用,如何显示数据?

添加了web引用.
using GetWeather;
Anonymous Anonymous = new Anonymous();

System.Xml.XmlReader XmlReader = Anonymous.GetWeather();
System.Xml.XmlNode XmlNode = Anonymous.GetHotArticleList();        //DataSet ds = new DataSet();
        //ds.ReadXml(Anonymous.GetHotArticleList());
        //this.GridView1.DataSource = ds;
        //this.GridView1.DataBind();以上代码是错误的...
