导出excel模版

方法一：

public void ToExcel(){

//第一步：获取模版物理路径

string file_1 = Server.MapPath("/Content/Excel/downExcel.xls");

//第二步： 写入客户端

System.IO.FileInfo filet = new System.IO.FileInfo(file_1);

Response.Clear();

Response.Charset = "GB2312";

Response.ContentEncoding = System.Text.Encoding.UTF8;

// 添加头信息，为"文件下载/另存为"对话框指定默认文件名

if (file_0.IndexOf(".xlsx") > 0){

Response.AddHeader("Content-Disposition", "attachment; filename=" + Server.UrlEncode("订单详情.xlsx"));

}

else if (file_0.IndexOf(".xls") > 0){

Response.AddHeader("Content-Disposition", "attachment; filename=" + Server.UrlEncode("订单详情.xls"));

}

// 添加头信息，指定文件大小，让浏览器能够显示下载进度

Response.AddHeader("Content-Length", filet.Length.ToString());

// 指定返回的是一个不能被客户端读取的流，必须被下载

Response.ContentType = "application/ms-excel";

// 把文件流发送到客户端

Response.WriteFile(filet.FullName);

// 停止页面的执行

Response.End();

}

方法二：

public void  excelModel(){

//第一步：获取模版物理路径

string path= Server.MapPath("/Content/Excel/downExcel.xls");

//第二步：写入客户端

FileStream fs = new FileStream(path, FileMode.Open);

byte[] bytes = new byte[(int)fs.Length];

fs.Read(bytes, 0, bytes.Length);

fs.Close();

Response.Charset = "UTF-8";

Response.ContentEncoding = System.Text.Encoding.GetEncoding("UTF-8");

Response.ContentType = "application/octet-stream";

Response.AddHeader("Content-Disposition", "attachment; filename=" + HttpUtility.UrlEncode(fileName));

Response.BinaryWrite(bytes);

Response.Flush();

Response.End();

return new EmptyResult();

}
