怎么实现往已有的excel文件模板里写入一个dataset的值。有例子吗?谢谢!

最好能给一个完整的例子,dataset准备写入的窗格是从C4到W16的长方形区域里(这个应该不重要的)。救急!

Excel.Application xlApp = New Excel.Application();
Excel.Workbook xlBook = new Excel.Workbook();
Excel.Worksheet xlSheet =new Excel.Worksheet();
int rowIndex = 0;
int colIndex = 0;
xlBook = xlApp.Workbooks().Add;
xlSheet = xlBook.Worksheets("sheet1");

int i, j, rowcount, columncount;
rowcount = DataGrid1.VisibleRowCount;
columncount = DataGrid1.VisibleColumnCount;

For (i = 0;i=rowcount - 2;i++)
{
rowIndex = rowIndex + 1;
For (j = 0 ;j= columncount - 1;j++)
{
colIndex = colIndex + 1
xlApp.Cells(rowIndex, colIndex) = DataGrid1.Item(i, j);
}
colIndex = 0;
}

参考:
objExcelSheet.Range("B3:K3").Value = Array("67", "87", "5", "9", "7", "45", "45", "54", "54", "10")

myRange = myWorksheet.get_Range("C4", "W16");
然后将数据添加进取就行,操作和worksheet的cells一样
