如何在ASP.Net MVC中读取文件的内容? [英] How can I read the contents of a file in ASP.Net MVC?

问题描述

我有一个ASP.Net MVC控制器操作，该操作需要返回包含另一个html文件内容的j​​son结果(实际上是jsonp，但这并不重要).所以基本上，我想这样做:

I have an ASP.Net MVC controller action that needs to return a json result (it's actually jsonp, but that's not important) that contains the contents of another html file. So basically, I want to do this:

[JsonpFilter]
public JsonResult GetHeader()
{
    var html = System.IO.File.ReadAllText("/htm/external/header.htm");

    return Json(new { html = html }, JsonRequestBehavior.AllowGet);
}

但是，找不到正确的文件.当我希望它查看服务器的根目录时(当然加上/htm/external)，它正在C目录中查找(找不到路径'C:\ htm \ external \ header.htm'的一部分).

However, it's not finding the right file. It's looking in the C directory (Could not find a part of the path 'C:\htm\external\header.htm'), when I want it to look at the server's root (plus /htm/external, of course).

如何读取此文件?它在外部可用，因此我想我可以对其进行单独的Web请求，但看来我应该可以直接将其定位为目标.

How can I read this file in? It's externally available, so I guess I could make a separate web request for it, but it seems like I should be able to target it directly.
