我如何才能找到从控制器构造函数，ASP.NET MVC中的文件夹路径？ [英] How Can I Find The Path To A Folder from a Controller Constructor in ASP.NET MVC?

问题描述

我想获得的文件夹路径在我的网站的根，并将其保存到时候我的控制器调用构造函数的类属性：

I am trying to get the path to a folder in my website root and save it to a class property when my controller constructor is called:

public TestController:Controller{
    string temp;

    public TestController(){
        temp = "";
        }

    }

我已经试过如下：

I have tried the following:

temp = Server.MapPath("~/TheFolder/"); // Server is null - error.
temp = Request.PhysicalApplicationPath + @"TheFolder\"; // Request is null - error.

任何想法？

推荐答案

AppDomain.CurrentDomain.BaseDirectory会给你的网站的根目录。所以：

AppDomain.CurrentDomain.BaseDirectory will give you the root of your site. So:

temp = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "TheFolder");
