想要替代Response.End()

本文关键字：End Response | 更新日期: 2023-09-27 18:22:46

我尝试在下载文件后删除文件。我的代码是

private void DownloadZipFileDialogue(string strZipFilePath)
{
  Response.ContentType = "application/octet-stream";
  Response.AppendHeader("Content-Disposition", "attachment; filename=" +   Path.GetFileName(strZipFilePath));
  Response.TransmitFile(strZipFilePath);
  Response.End();
  //File.Delete(strZipFilePath);
 }

我知道Response.End();之后没有代码块被执行。如果我试图在Response.End(); zip文件损坏之前删除文件。我到处找。我尝试：
ApplicationInstance.CompleteRequest();
代替
Response.End();
但我得到了相同的结果。zip文件已损坏。我看到这是Response.End（）被认为是有害的吗？但无法找到解决方案。任何解决问题的想法。谢谢

你可以试试这个，

private void DownloadZipFileDialogue(string strZipFilePath)
{
  Response.ContentType = "application/octet-stream";
  Response.AppendHeader("Content-Disposition", "attachment; filename=" +   Path.GetFileName(strZipFilePath));
    using(Stream input = File.OpenRead(strZipFilePath)){
       /// .NET 4.0, use following line if its .NET 4 project
       input.CopyTo(Response.OutputStream);
       /// .NET 2.0, use following lines if its .NET 2 project
       byte[] buffer = new byte[4096];
       int count = input.Read(buffer,0,buffer.Length);
       while(count > 0){
          Response.OutputStream.Write(buffer,0,count);
          count = input.Read(buffer,0,buffer.Length);
       }
    }
    File.Delete(strZipFilePath);
}
