public partial class Default2 : System.Web.UI.Page

    protected void Page_Load(object sender, EventArgs e)
    {

    }

    protected void Button1_Click(object sender, EventArgs e)
    {
        XmlDocument xdoc = new XmlDocument();
        SqlConnection cnn = null;
        SqlCommand cmd = null;



        try
        {
            cnn = new SqlConnection();
            cnn.ConnectionString = "ICDBConnectionString";
            cnn.Open();

            string selectQry = "WITH XMLNamespaces('TUReport' AS Debtor) SELECT* FROM TUReport WHERE ConsumerID = @ID FOR XML RAW('TUReport');";
            cmd = new SqlCommand(selectQry, cnn);
            int ID = Convert.ToInt32(txtIDNumber.Text);
            cmd.Parameters.AddWithValue("@ID", ID);

            DataSet dataset = new DataSet();

            //System.IO.StringReader xmlSR = new System.IO.StringReader(cmd)

            XmlReader reader = cmd.ExecuteXmlReader();

            dataset.ReadXml(reader, XmlReadMode.ReadSchema);

            results.DataSource = reader;
            results.DataBind();
            cnn.Close();


            //if (reader.Read())

            //    xdoc.Load(reader);


        }

        catch (Exception ex)
        {
            throw ex;
        }

        finally
        {
            cmd.Dispose();
            cnn.Close();
        }

    }
}

SQL之间缺少一个空格＆＃39;选择＆＃39;和＆＃39; ＆＃39;。（选择 FROM TUReport）
