Question

How can i use the server.mappath method in a C# class library class ,which acts as my BusinessLayer for My ASP.NET WEbsite

Answer 1

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

Answer 2

By calling it?

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

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

Answer 3

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

HostingEnvironment.MapPath("~/file")

Wonder why nobody mentioned it here.

Answer 4

You can get the base path by using the following code and append your needed path with that.

string  path = System.AppDomain.CurrentDomain.BaseDirectory;

Answer 5

You should reference System.Web and call:

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

Answer 6

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