Server.Mappath in C # classlibrary

Question

How can I use the server.mappath method in a C # class library class that acts like my BusinessLayer for my ASP.NET website

Answer 1

Calling him up?

var path = System.Web.HttpContext.Current.Server.MapPath("default.aspx"); 

Make sure you add the reference to the System.Web assembly.

Answer 2

You can get the base path using the following code and adding the path you need.

 string path = System.AppDomain.CurrentDomain.BaseDirectory; 

Answer 3

You should contact System.Web and call:

  HttpContext.Current.Server.MapPath(...) 

Answer 4

Perhaps you could abstract this as a dependency and create an IVirtualPathResolver. Thus, your service classes will not be tied to System.Web, and you can create another implementation if you want to reuse your logic in a different user interface technology.

Answer 5

Use this System.Web.Hosting.HostingEnvironment.MapPath () .

 HostingEnvironment.MapPath("~/file") 

I wonder why no one mentioned it here.

Answer 6

HostingEnvironment.MapPath

System.Web.Hosting.HostingEnvironment.MapPath (path);

Answer 7

Architecturally, System.web should not be referenced in the Business Logic Layer (BLL). Use BLL in your solution structure to follow a separate principle of concern, so refer to System.Web, this is bad practice. BLL should not load / run in the context of Asp.net. For reasons you should consider using System.AppDomain.CurrentDomain.BaseDirectory instead of System.Web.HttpContext.Current.Server.MapPath
