对EXCEL操作

 

string strFileName = "D:\\temp\\aaaa.xls";
Excel.Application app = new Excel.ApplicationClass();
Excel.Workbook ThisWorkBook;
object missing = System.Reflection.Missing.Value;
app.Visible = false;
app.UserControl = true;
Workbooks workbooks = app.Workbooks;
_Workbook workbook = workbooks.Add(strFileName);//这里的Add方法里的参数就是模板的路径
Sheets sheets = workbook.Worksheets;
_Worksheet worksheet = (_Worksheet)sheets.get_Item(1); //这里表示模板只有一个sheet表
ThisWorkBook = app.Workbooks.Open(strFileName, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing);
Excel.Worksheet ThisSheet = (Excel.Worksheet)ThisWorkBook.Sheets[1];
app.Visible = false;
worksheet.Cells[5, 8] = name;  //写入数据
worksheet.SaveAs(strSaveFileName, missing, missing, missing, missing, missing, missing, missing, missing, missing);
worksheet.PrintOut(missing, missing, 1, false, comb.SelectedValue, false, true, "");

app.Quit();  //清空
ThisWorkBook = null;
app = null;
dt = null;
