在c#中動態生成水晶報表時，動態添加sort

代碼 private void SetSortQuick(ReportClientDocument objRPT)
    {
      if (!String.IsNullOrEmpty(this.SortField))
      {
        cCreateReport objCreateReport = new cCreateReport();
        string[] arrySortField = this.SortField.Split(new char[] { , });
        string[] arrySortDirection = this.SortDirection.Split(new char[] { , });
        for (int i = 0; i < arrySortField.Length; i++)
        {
          string[] arryTemp = arrySortField[i].Split(new char[] { | });
          string strFieldName = arryTemp[0];
          string strFieldType = arryTemp[1].ToLower();

          string strFormula = "", strFormulaName = "";
          switch(strFieldType)
          {
            case "datetime":
              strFormula = "date({" + arrySortField[i] + "})";
              break;
            case "numeric":
            case "int":
            case "money":
            case "float":
              strFormula
