query result what should i use Count() or Any()

Question

I am checking login of a user by this repository method,

  public bool getLoginStatus(string emailId, string password)
    {
        var query = from r in taxidb         


        

Answer 1

You could express it quite a bit shorter like this:

return taxidb.Registrations.Any(r => r.EmailId == emailId && r.Password==password);
