How to check if user have ReadAccess for an account in Dynamics CRM usind C#

Question

I am following this walkthrough for getting the access of a user to an account in dynamics crm using C#. When I tried to check that if user have AppendAccess it is not working properly and while debugging I found these rights in the following form.

I want to check if a user have AppendAccess then do the next. what I tried is in the following:

if(principalAccessRes.AccessRights.Equal("AppendAccess "))
{
Console.WriteLine("User have Append Access");
}

Answer 1

Because AccessRights is a [Flag] you need to check if the access rights response includes (HAVE) instead of equal.

if(principalAccessRes.AccessRights.HasFlag(AccessRights.AppendAccess))
{
   Console.WriteLine("User have Append Access");
}
