SqlDataAdapter sda = new SqlDataAdapter(strQuery, myConnection); DataSet ds = new DataSet(); sda.Fill(ds); XPathNavigator node = navigator.SelectSingleNode("/my:myFields/my:field2", this.NamespaceManager); string strNS = node.NamespaceURI; foreach (DataRow row in ds.Tables[0].Rows) { using (XmlWriter xw = node.AppendChild()) { xw.WriteStartElement("myFields", strNS); xw.WriteElementString("field2", strNS, row["CourseTime"].ToString()); //"CourseTime" is the column in the query xw.WriteEndElement(); xw.Flush(); xw.Close(); //ERROR: Schema validation found non-data type errors. } } } How do I resolve the ERROR above? I am looking to clear out the entries for the ListBox and re-populate with the DataSet.
