问题描述
在的WebForms,我通常有code这样让浏览器present一个下载文件弹出一个任意文件类型,如PDF,和文件名:
In WebForms, I would normally have code like this to let the browser present a "Download File" popup with an arbitrary file type, like a PDF, and a filename:
Response.Clear()
Response.ClearHeaders()
''# Send the file to the output stream
Response.Buffer = True
Response.AddHeader("Content-Length", pdfData.Length.ToString())
Response.AddHeader("Content-Disposition", "attachment; filename= " & Server.HtmlEncode(filename))
''# Set the output stream to the correct content type (PDF).
Response.ContentType = "application/pdf"
''# Output the file
Response.BinaryWrite(pdfData)
''# Flushing the Response to display the serialized data
''# to the client browser.
Response.Flush()
Response.End()
如何完成相同的任务在ASP.NET MVC?

推荐答案
从你的行动返回一个FileResult或FileStreamResult,取决于文件是否存在,或者您即时创建它。
Return a FileResult or FileStreamResult from your action, depending on whether the file exists or you create it on the fly.
public ActionResult GetPdf(string filename)
{
return File(filename, "application/pdf", Server.UrlEncode(filename));
}
