Ubiquitous way to get the file system root of a .NET WEB application

Question

Similar to Ubiquitous way to get the root directory an application is running in via C#, but that question seems to be related to Win Forms. How would the same be done for Web Forms?

I was using...

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

This works great for handling HTTP requests but seems not to work if a scheduler like Quartz.NET invokes a job (the problem I am having). The HttpContext.Current is null in that scenario since an actual HTTP request is not made.

Answer 1

Try the System.Web.Hosting.HostingEnvironment.MapPath method. AFAIK it's not dependent on HttpContext so you should be able to use it from a background thread.

Answer 2

You're looking for the HttpRuntime.AppDomainAppPath property, and perhaps the VirtualPathUtility class.

Answer 3

Use AppDomain.CurrentDomain.BaseDirectory. This corresponds to AppDomainSetup.ApplicationBase which states that it is 'The name of the application base directory.'
