c# - Why I can't use Server.MapPath() in my class? -

-

i have following problem when try call server.mappath(); inside class.

it give me following error message:

error 3 name 'server' not exist in current context c:\develop\earlywarning\public\implementazione\ver2\pdfreport\itextdocumentbase.cs 122 13 pdfreport

so think maybe have add namespace related server object looking on official documentation can't found no related namespace: http://msdn.microsoft.com/en-us/library/ms525541%28v=vs.90%29.aspx

why? can solve?

tnx

do in class:

system.web.httpcontext.current.server.mappath("relative path");
