How to check if a user has permission to a SharePoint site collection -

-

what best way check if user has permission site collection/site? i'm using following

   spsecurity.runwithelevatedprivileges(        () => {using (var site = new spsite(nodeurl))                      {                          using (var web = site.openweb())                          {                              retvalue=                                  web.doesuserhavepermissions(                                      context.user.identity.name,                                      spbasepermissions.open);                          }                      }              });

this doesn't seem working properly. if user never added site works. if user added , removed doesuserhavepermission(.. spbasepermission.open) still returns true, when user tries access site sharepoint throws access denied page.

after little more digging found user account still in web.allusers list, has no roles assigned.

use checkpermissions instead of doesuserhavepermissions. see spweb.checkpermissions method .
