asp.net 导出Excel方法汇总

第一种：需要引用com ：microsoft.excel.11.0.
//生成Excel文件的代码
protected void ExportExcel()
{
Microsoft.Office.Interop.Excel.Application excel = new Microsoft.Office.Interop.Excel.Application();
Microsoft.Office.Interop.Excel.Workbook wb = excel.Workbooks.Add(Microsoft.Office.Interop.Excel.XlWBATemplate.xlWBATWorksheet); // 创建工作簿
Microsoft.Office.Interop.Excel.Worksheet ws = (Microsoft.Office.Interop.Excel.Worksheet)wb.Worksheets[1]; // 创建工作页
DataSet ds = GetData();
int iMaxRow = ds.Tables["rsData"].Rows.Count;
int iMaxCol = ds.Tables["rsData"].Columns.Count;
// 设置格式
ws.get_Range(ws.Cells[1, 1], ws.Cells[1, iMaxCol]).Font.Name = "黑体";
ws.get_Range(ws.Cells[1, 1], ws.Cells[1, iMaxCol]).Font.Bold = true;
ws.get_Range(ws.Cells[1, 1], ws.Cells[iMaxRow + 1, iMaxCol]).Borders.LineStyle = 1;
// 设置标题
excel.Cells[1, 1] = "班级";
excel.Cells[1, 2] = "学号";
excel.Cells[1, 3] = "姓名";
excel.Cells[1, 4] = "性别";
// 填充数据
for (int iRow = 0; iRow < iMaxRow; iRow++)
{
for (int iCol = 0; iCol < iMaxCol; iCol++)
{
excel.Cells[iRow + 2, iCol + 1] = ds.Tables["rsData"].Rows[iRow][iCol].ToString();
}
}
// 保存Excel
excel.Save("学生基础信息");
// 打开Excel
excel.Visible = true;
}
 第二种：利用 System.IO
public void CreateExcel(DataSet ds, string typeid, string FileName)
{
HttpResponse resp;
resp = Page.Response;
resp.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");
resp.ContentType = "application/ms-excel";
resp.AddHeader("Content-Dispositi
