ASP.NET MVC 6应用程序的虚拟应用程序根路径 [英] ASP.NET MVC 6 application's virtual application root path

问题描述

如何获取服务器上应用程序的虚拟根路径?

How do I get the virtual root path of the application on the server?

换句话说:如何在ASP.NET MVC 6中执行以下操作?

In another words: how can I do the following in ASP.NET MVC 6?

推荐答案

您可以使用@Url.Content("~/")实现所需的功能，它将〜"映射到您的虚拟应用程序根路径.

What you need can be achieved with @Url.Content("~/"), which will map "~" to your virtual application root path.

看看

Having a look at the source code, it seems to do so using the HttpContext.Request.PathBase property:

public virtual string Content(string contentPath)
{
    if (string.IsNullOrEmpty(contentPath))
    {
        return null;
    }
    else if (contentPath[0] == '~')
    {
        var segment = new PathString(contentPath.Substring(1));
        var applicationPath = HttpContext.Request.PathBase;

        return applicationPath.Add(segment).Value;
    }

    return contentPath;
}
