为什么波浪号和斜杠在Asp.net MVC应用程序中不起作用? [英] Why tilde and slash doesnt work in Asp.net MVC application?

问题描述

当我编写此代码时

string[] filePaths = Directory.GetFiles(@"~/Content/Images/");

我得到 System.IO.DirectoryNotFoundException:找不到路径'C:\ Program Files(x86)\ IIS Express \ Content \ Images'的一部分.我应该如何正确书写?我有图像"和内容"文件夹，并且我不想对路径进行硬编码.另外，当我使用html代码(例如< img src =〜/Content/Images/Img.jpg")

I get System.IO.DirectoryNotFoundException: Could not find a part of the path 'C:\Program Files (x86)\IIS Express\Content\Images'. How should I write correctly? I have the folder "Images" and "Content", and I dont want to hardcode a path. Also, it works when I write in html code like <img src="~/Content/Images/Img.jpg" for example

推荐答案

将 HostingEnvironment.ApplicationPhysicalPath 与 Path.Combine 结合使用，例如:

string[] filePaths = Directory.GetFiles(Path.Combine
                             (HostingEnvironment.ApplicationPhysicalPath, 
                              "Content/Images"));

或

使用 HttpContext.Current.Server.MapPath ，例如:

string[] filePaths = Directory.GetFiles(HttpContext.Current.Server.MapPath
                                        (@"~/Content/Images/"));
