Excel.Application excel=new Excel.Application();
Excel.Workbooks workbooks = excel.Workbooks;
Excel._Workbook workbook1=excel.Workbooks.Add(XlWBATemplate.xlWBATWorksheet);
Sheets sheets = workbook1.Worksheets;
_Worksheet worksheet = (_Worksheet) sheets.get_Item(1);   int rowIndex=1;
int colIndex=0; //循环读取生成新表格
excel.Application.Workbooks.Add(true);              //生成EXCEL的格式设定
excel.Cells.Font.Bold = false;
excel.Cells.FillLeft();
excel.Cells.Font.Size = "9";

//引用函数GetData中所取出的数据，得到数据源
System.Data.DataTable  table =dt;

//将所得到的表的列名,赋值给单元格
foreach(DataColumn col in table.Columns)
{
colIndex++;
excel.Cells[1,colIndex]=col.ColumnName;
}
//同样方法处理数据 foreach(DataRow row in table.Rows)
{

//处理各列的数据
foreach(DataColumn col in table.Columns)
{
colIndex++;
excel.Cells[rowIndex,colIndex]=row[col.ColumnName].ToString();
}
}
//不可见,即后台处理
excel.Visible=true;
//友好界面提示
//Label1.Text="操作成功，请另存生成的表格！";

将DataGrid输出到Excel文件
huzhishan.yeah.net 2003-10-28 个人工作室
在Web From上输出数据到Excel有两种方法，一个是有数据库直接导出；另外一个方法是由DataGrid直接输出到Excel文件。下面得代码实现了这两个功能。注意：在使用时要引用Microsoft Office Web Components 9.0 COM组件，另外注意设置要保存文件得目录具有匿名可修改的权限。DataGridToExcel.aspx<%@ Page Language="vb" EnableViewState="False" AutoEventWireup="false" Codebehind="DataGridToExcel.aspx.vb"
