Cannot use Server.MapPath

问题:

What I must do to make Server.MapPath work?
I have using System.Web;

what else? When I type Server there is no quick result option (intelli-sense) for Server.

Any help?

回答1:

you can try using this

    System.Web.HttpContext.Current.Server.MapPath(path);

or use HostingEnvironment.MapPath

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

回答2:

Your project needs to reference assembly System.Web.dll. Server is an object of type HttpServerUtility. Example:

HttpContext.Current.Server.MapPath(path);

回答3:

System.Web.HttpContext.Current.Server.MapPath("~/") gives null if we call it from a thread.

So, Try to use

System.Web.Hosting.HostingEnvironment.MapPath("~/")

回答4:

Firt add a reference to System.web, if you don't have. Do that in the References folder.

You can then use Hosting.HostingEnvironment.MapPath(path);

回答5:

Try adding System.Web as a reference to your project.
