我有一个制度,可以把一个旁观阵列(不了解其pdf、txt或 doc)提供给我的可下载档案。 如今,通常在伙伴关系中。 NET MVC 我希望这样做。
return File(labTestResult.File, "application/pdf");
之所以容易,是因为我知道档案类型是什么。 既然档案类型可能是什么,那么能否将档案下载到适当的格式?
Asp.net MVC非常容易,因此,如果你需要以不同的方式在答复中发出任何信息,即你可以撰写一份行动说明,供你使用,而不必具体说明奇梅类型,但确实不建议这样做。
如果你也能够确定使用该守则的习俗行动结果,那么你的控制器代码就成为:return AutoMimeFile(labResult.File);。
我确信,这样做确实是好的。 某些档案格式有“磁号”,可查到:Here,用于更多这方面的信息。 我从未亲自尝试过,因此,我可以说,这种执行将多么坚实。 我认为最好的方法是用数据检索文档类型。
