DataTable distinctTable = dTable.DefaultView.ToTable(true,"ITEM_NO","ITEM_STOCK");
DataTable dtSummerized = new DataTable("SummerizedResult");

dtSummerized.Columns.Add("ITEM_NO",typeof(string));
dtSummerized.Columns.Add("ITEM_STOCK",typeof(double));

int count=0;

foreach(DataRow dRow in distinctTable.Rows)
{
  count++;
  //string itemNo = Convert.ToString(dRow[0]);
  double TotalItem = Convert.ToDouble(dRow[1]);

  string TotalStock = dTable.Compute("sum(" + TotalItem + ")", "ITEM_NO=" + dRow["ITEM_NO"].ToString()).ToString();
  dtSummerized.Rows.Add(count,dRow["ITEM_NO"],TotalStock);
}

错误消息:聚合参数中的语法错误:期望具有可能的"子"限定符的单个列参数.

有人可以帮帮我吗？

谢谢.
