Question

I have a LINQ query that brings back all records from a table called Permissions, where the userId is the current user.

What I want to do is run a check on this result set and see if PermissionId of value 5 exists..

Whats the easiest way to do this?

Answer 1

var PermissionIDFiveCount=YourInitialDataset.Where(p=>p.PermissionID==5).Count()

Or shorter way:

var PermissionIDFiveCount=YourInitialDataset.Count(p=>p.PermissionID==5)

Even shorter:

var ContainsPermissionIDFive=YourInitialDataset.Any(p=>p.PermissionID==5)
