Excel._Workbook xBk;        //工作薄
       Excel._Worksheet xSt;   //工作Sheet  

xBk = myExcel.Workbooks.Add(true);

for (int i = 0; i < 1; i++)
       {
         xSt = (Excel._Worksheet)xBk.ActiveSheet;
         xSt.Name = "Sheet" + i;
         myExcel.Sheets.Add(missing, missing, 1, Excel.XlSheetType.xlWorksheet);
       }
       //myExcel.Visible = true;
