How to get Active Directory Attributes not represented by the UserPrincipal class

Question

What I mean is that right now I am using System.DirectoryServices.AccountManagement and if I use UserPrincipal class I only see the Name, Middle Name, etc

so in my codes it like

UserPrincipal myUser = new UserPrincipal(pc);
myUser.Name = "aaaaaa";
myUser.SamAccountName = "aaaaaaa";
.
.
.
.
myUser.Save();

How would I see the attribute like mobile or info?

In this case, you need to go one level deeper - back into the bowels of DirectoryEntry - by grabbing it from the user principal:

using (DirectoryEntry de = myUser.GetUnderlyingObject() as DirectoryEntry)
{
    if (de != null)
    {
        // Go for those attributes and do what you need to do...
        var mobile = de.Properties["mobile"].Value as string;
        var info = de.Properties["info"].Value as string;
    }
}
