“线程被终止”启动下载时出现运行时错误

情况：

在一个 C# 网站项目中，我从数据库中获取数据并将所需数据写入 Excel 文件服务器端，然后我希望提供下载。

问题：

在启动下载的代码末尾（见下文），我收到一个运行时错误，该错误表明线程已终止并且没有提供文件可供下载。

我的代码

FileStream fStream = new FileStream(resultFile, FileMode.Open, FileAccess.Read);
byte[] byteBuffer = new byte[(int)fStream.Length];
fStream.Read(byteBuffer, 0, (int)fStream.Length);
fStream.Close();

response.Clear();
response.ContentType = "application/vnd.ms-excel";
response.AddHeader("Content-Length", byteBuffer.Length.ToString());
response.AddHeader("Content-Disposition", "attachment; filename=" + Path.GetFileName(resultFile));
response.TransmitFile(resultFile);
response.End();

我希望有人能帮助我解决这个问题。提前致谢：）

The situation:

In a C# web site project I am getting data out of a database and write the required data to an excel file server side, which I then want to offer for downloading.

The problem:

At the end of the code to initiate a download (See below) I get a runtime error that the thread is terminated and no file is offered for downloading.

My code

FileStream fStream = new FileStream(resultFile, FileMode.Open, FileAccess.Read);
byte[] byteBuffer = new byte[(int)fStream.Length];
fStream.Read(byteBuffer, 0, (int)fStream.Length);
fStream.Close();

response.Clear();
response.ContentType = "application/vnd.ms-excel";
response.AddHeader("Content-Length", byteBuffer.Length.ToString());
response.AddHeader("Content-Disposition", "attachment; filename=" + Path.GetFileName(resultFile));
response.TransmitFile(resultFile);
response.End();

I hope somebody can help me with this. Thanks in advance :)

我使用以下代码下载Excel

   FileStream fs = File.OpenRead(path);
   byte[] data = new byte[fs.Length];
   fs.Read(data, 0, (int)fs.Length);
   Response.Buffer = true;
   Response.ContentType = "application/x-msdownload";
   Response.AddHeader("Content-Disposition", "attachment; filename=" + fileName  );
   Response.BinaryWrite(data);

I used following code to download Excel

   FileStream fs = File.OpenRead(path);
   byte[] data = new byte[fs.Length];
   fs.Read(data, 0, (int)fs.Length);
   Response.Buffer = true;
   Response.ContentType = "application/x-msdownload";
   Response.AddHeader("Content-Disposition", "attachment; filename=" + fileName  );
   Response.BinaryWrite(data);
