Quick & Dirty Check for Role Permissions on IContent

For some reason, this was not an easy one to find, since most articles focus only on the current user and not using the Episerver APIs for lookups against other users or roles. Though I find it a bit strange, a customer needs to display a list of documents and indicate which among those documents are publicly accessible versus private (members-only). 

Thanks to David Knipe, my Twitter-based weathervane, I came up with a relatively quick and simple set of static methds for doing just that. Providing them here for posterity, allowing you to check a given role for a given permission via a quick extension whenever and wherever you need it.

public static Boolean IsAvailableToEveryone(this T content) where T : IContent
    return content.RoleHasAccess(new[] { "Everyone" }, AccessLevel.Read);

public static Boolean RoleHasAccess(this T content, string[] roles, AccessLevel accessLevel) where T : IContent
    var securedContent = content as ISecurable;
    var descriptor = securedContent.GetSecurityDescriptor();
    var identity = new GenericIdentity("doesn't matter");
    var principal = new GenericPrincipal(identity, roles);
    return descriptor.HasAccess(principal, accessLevel);

The last method can't be working. accessLevel.HasFlag(accessLevel) is always true.

Thanks - idiot copy/paste on my part. Fixed the return. Had it right and then rewrote it poorly.

Good stuff James,

Just want to clarify one thing about this snippet. This code will only check that a role has access to the content according to it's assigned access rights. It won't take into consideration the published state or if the content has been deleted. To get this functionality you can use the IContentAccessEvaluator service.

eGandalf Oct 11, 2016 11:23 PM

Good point, Henrik. However, from what I can tell the IContentAccessEvaluator is an Episerver internal API, not one really intended for our consumption, so I'd prefer to not recommend it.

Seems easy enough to add a check for IsDeleted, though if it's truly generic and I'm not sure whether the content is a Page, Block, Media or other type of IContent, the published status doesn't seem as obvious to check.

eGandalf Oct 11, 2016 11:29 PM

I think I could add these two validators, since PageData has that convenient CheckPublishedStatus, but it still wouldn't cover Blocks or Media.

if (content.IsDeleted) return false;

if(content is PageData)


    if (!(content as PageData).CheckPublishedStatus(PagePublishedStatus.Published))

        return false;
