Posted 2021-02-27

Everything is either true or untrue, or both true and untrue, or neither true nor untrue

public static DataTable ConvertXmlNodeListToDataTable(XmlNodeList xnl)
        {
            DataTable dt = new DataTable();
            int TempColumn = 0;
 
            foreach (XmlNode node in xnl.Item(0).ChildNodes)
            {
                TempColumn++;
                DataColumn dc = new DataColumn(node.Name, System.Type.GetType("System.String"));
                if (dt.Columns.Contains(node.Name))
                {
                    dt.Columns.Add(dc.ColumnName = dc.ColumnName + TempColumn.ToString());
                }
                else
                {
                    dt.Columns.Add(dc);
                }
            }
 
            int ColumnsCount = dt.Columns.Count;
            for (int i = 0; i < xnl.Count; i++)
            {
                DataRow dr = dt.NewRow();
                for (int j = 0; j < ColumnsCount; j++)
                {
                    dr[j] = xnl.Item(i).ChildNodes[j].InnerText;
                }
                dt.Rows.Add(dr);
            }
            return dt;
        }
