推荐答案

此代码实际上在服务器文件系统中创建了一个PDF。您需要做的是读取文件，将其写入页面的响应流，设置正确的响应类型并关闭流。浏览器将根据用户设置采取适当的操作，即它可以在浏览器中打开文件进行查看，或者使用另存为对话框提示用户。

This code actually creates a PDF in the server file system. What you need to do is read the file, write it to the Response Stream of the page, set the correct Response Type and close the stream. The browser will take appropriate action based on user settings, i.e. it may open the file within the browser for viewing or prompt the user with the Save As dialog.
