4 个解决方案

#1

Server.MapPath("~");

Will get you the root directory of the current application, as a path on the disk. E.g., C:\inetpub\...

将获取当前应用程序的根目录，作为磁盘上的路径。例如,C:\ inetpub \…

Note that the ~ character can be used as part of web paths in ASP.NET controls as well, it'll fill in the URL to your application.

注意~字符可以用作ASP中的web路径的一部分。NET控件，它将填入到您的应用程序的URL。

If your class doesn't have Server property, you can use static

如果您的类没有服务器属性，您可以使用静态

HttpContext.Current.Server.MapPath("~")

#2

HttpRuntime.AppDomainAppPath is useful if you don't have a HttpContext available.

HttpRuntime。如果没有可用的HttpContext, AppDomainAppPath是有用的。

For example, a low-level library method to get a path relative to the current application, and it has to work whether it is a web app or not:

例如，一个低级库方法来获取与当前应用程序相关的路径，无论它是否是web应用程序，它都必须工作:

private static string GetDataFilePath() => HttpRuntime.AppDomainAppVirtualPath != null ?
    Path.Combine(HttpRuntime.AppDomainAppPath, "App_Data") :
    Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);

#3

You can get this from Server.MapPath method.

你可以从服务器上得到这个。MapPath方法。
