下载EPPlus.dll生成的excel文件时出现网络错误

本文关键字:网络 错误 文件 excel dll EPPlus 下载 | 更新日期: 2023-09-27 18:08:10

我尝试从asp.net c# web表单应用程序下载由EPPlus.dll制作的excel文件。但我得到失败-网络错误。值得注意的是,上面提到的错误只发生在chrome浏览器中,在其他浏览器中也可以成功完成。

这个错误不会发生在我的本地主机上,它只发生在主服务器上。 如果有人能解释一下这个问题的解决方法,那就太有帮助了。 http://www.irandnn.ir/blog/PostId/29/epplus

下载EPPlus.dll生成的excel文件时出现网络错误

当我使用Response.Clear()和Response.Close()时,我遇到了同样的问题,并且不得不避免它们来查看我的代码,如下所示。

Response.Buffer = true;
Response.ContentType = mimeType;
Response.AddHeader("Content-Disposition", "attachment; filename=" + nameOfFile);
Response.BinaryWrite(bytes);
Response.End();

试试这个:

using (ExcelPackage p = new ExcelPackage())
{
    //Code to fill Excel file with data.

    Byte[] bin = p.GetAsByteArray();
    Response.ClearHeaders();
    Response.ClearContent();
    Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
    Response.AddHeader("Content-Disposition", string.Format("attachment;filename={0}", Nombre_Del_Libro + ".xlsx"));
    Response.BinaryWrite(bin);
    Response.Flush();
    Response.End();
}   

我不喜欢使用response.End(),因为会抛出异常

    protected void DownloadFile(FileInfo downloadFile, string downloadFilename, string downloadContentType)
    {
        Byte[] bin = File.ReadAllBytes(downloadFile.FullName); 
        Response.ClearHeaders();
        Response.ClearContent();
        Response.ContentType = downloadContentType;
        Response.AddHeader("Content-Disposition", string.Format("attachment;filename={0}", downloadFilename ));
        Response.BinaryWrite(bin);
        Response.Flush();
        Response.SuppressContent = true; 
    }

我遇到了同样的问题,我用下面的代码解决了,注意filename='"Name.xlsx'":

中的引号
Response.Buffer = true;
Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
Response.AppendHeader("content-disposition", "attachment; filename='"Name.xlsx'"");
//Writeout the Content  
Response.BinaryWrite(bytes);

我正在导出html表格代码,这是在字符串变量html

下面的代码为我工作

byte[] myFile = Encoding.ASCII.GetBytes(HTML);
        Response.Clear();
        Response.Buffer = true;
        Response.AddHeader("Content-Type", "application/excel");
        Response.AddHeader("Content-Disposition", string.Format("attachment;filename={0};", "BAGrowthReport.xls"));
        Response.AddHeader("content-length", myFile.Length.ToString()); //Here is the additional header which is required for Chrome.
        Response.BinaryWrite(myFile);
        Response.Flush();
        Response.Close();
