方法一:拼html
新建一个一般处理程序
public void ProcessRequest(HttpContext context)
{
context.Response.ContentType = "text/plain";
context.Response.Clear();
context.Response.Buffer = true;
context.Response.Charset = "utf-8";
context.Response.AppendHeader("Content-Disposition", "attachment;filename=" + context.Server.UrlEncode("Excel名称") + ".xls");
context.Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");//设置输出流为简体中文
context.Response.ContentType = "application/vnd.ms-excel";//设置输出文件类型为excel文件。
context.Response.Write("表头1\t");
context.Response.Write("表头2\t");
context.Response.Write("表头3\t");
context.Response.Write("\n");
for (int i = 0; i < 100;i++ )
{
context.Response.Write("aaa" + "\t");
context.Response.Write("bbb" + "\t");
context.Response.Write("ccdd" + "\t");
context.Response.Write("\n");
}
context.Response.End();
}
就可以进行最简单的导出excel,当然也可以写在asp.net mvc中的Controller的方法里,效果也一样
public class TreeController : Controller
{
public void ToExcelTest()
{
HttpContext.Response.ContentType = "text/plain";
HttpContext.Response.Clear();
HttpContext.Response.Buffer = true;
HttpContext.Response.Charset = "utf-8";
HttpContext.Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpContext.Server.UrlEncode("Excel名称") + ".xls");
HttpContext.Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");//设置输出流为简体中文
HttpContext.Response.ContentType = "application/vnd.ms-excel";//设置输出文件类型为excel文件。
HttpContext.Response.Write("<table cellpadding='1' cellspacing='1'>");
HttpContext.Response.Write("<tr >");
HttpContext.Response.Write("<td> sucessful3333"); HttpContext.Response.Write("</td>");
HttpContext.Response.Write("<td> sucessful2"); HttpContext.Response.Write("</td>");
HttpContext.Response.Write("</tr>");
HttpContext.Response.Write("</table>");
Response.End();
HttpContext.Response.End();
}
}
方法二:使用npoi
public void sccussful()
{
HSSFWorkbook workbook = new HSSFWorkbook();
MemoryStream ms = new MemoryStream();
// 新建表
Sheet sheet = workbook.CreateSheet("My Sheet");
Row r = sheet.CreateRow(0);
r.Height = 26 * 20;
Cell c = r.CreateCell(0);
c.SetCellValue("公司:xx" + "QQ:" + 123456789+" \n mmmww");
//设置样式
CellStyle style = workbook.CreateCellStyle();
style.Alignment = HorizontalAlignment.CENTER;
style.VerticalAlignment = VerticalAlignment.CENTER;
style.WrapText = true;//配合\n使用进行换行
Font font = workbook.CreateFont();
font.FontHeight = 13 * 13;
font.Boldweight = short.MaxValue;//加粗
font.FontName = "微软雅黑";
font.Color = HSSFColor.RED.index;
style.SetFont(font);
c.CellStyle = style;
Row r2 = sheet.CreateRow(1);
r2.CreateCell(0).SetCellValue("gg");
r2.CreateCell(1).SetCellValue("mm");
r2.CreateCell(2).SetCellValue("22222");
//设置列宽
sheet.SetColumnWidth(0, 16 * 256);
sheet.SetColumnWidth(1, 20 * 256);
sheet.SetColumnWidth(2, 20 * 256);
//合并单元格
CellRangeAddress cellRangeAddress = new CellRangeAddress(0, 0, 0, 2);
sheet.AddMergedRegion(cellRangeAddress);
workbook.Write(ms); Response.AddHeader("Content-Disposition", string.Format("attachment; filename=EmptyWorkbook.xls"));
Response.BinaryWrite(ms.ToArray());
workbook = null;
ms.Close();
ms.Dispose();
} 这里设置值和生成列的顺序必须一一对应,如果数据多了 改一个,或者删除一下移动重新调整比较麻烦,可以用一个计数器记录下下标
public void GetpriceListExport_DZG()
{
int Count = 0;
List<DTO_Price_Info> list = _Price_Info.GetPrice_Info_List_Select();
HSSFWorkbook workbook = new HSSFWorkbook();
MemoryStream ms = new MemoryStream();
// 新增試算表。

}用模板导出Excel,有些比较复杂的表头,我们就不用代码里边构建了
private HSSFWorkbook getWorkBook(string templetPath)
{
FileStream file = new FileStream(templetPath, FileMode.Open, FileAccess.Read);
HSSFWorkbook workbook = new HSSFWorkbook(file);
return workbook;
}
public void ToExcel(List<DTO_Price_Info> _params)
{
HSSFWorkbook workbook = getWorkBook("d://PSTAR运价导入模版.xls");//读取模板
MemoryStream ms = new MemoryStream();
Sheet sheet = workbook.GetSheet("整箱导出");//读取表
//添加数据
int i = 2;
int position = 0;
foreach (DTO_Price_Info item in _params)
{
Row ir = sheet.CreateRow(i);
ir.Height = 20 * 20;
ir.CreateCell(1).SetCellValue("上海");
ir.CreateCell(2).SetCellValue("200");
}
//导出excel
workbook.Write(ms); Response.AddHeader("Content-Disposition", string.Format("attachment; filename=PSTAR.xls"));
Response.BinaryWrite(ms.ToArray());
workbook = null;
ms.Close();
ms.Dispose();
}
