Active Directory and C# II

To continue this series of posts, I'd now like to talk about groups and my group helper class. It is actually quite simple and kind of looks just like the User helper. You can download all the files from here.

using System;
using System.Collections.Generic;
using System.Text;
using System.DirectoryServices;
using ActiveDs;

namespace AdLib
{
 public class AdGroup : IDisposable
 {
     private DirectoryEntry _entry;
     private IADsGroup _group;

     public AdGroup(DirectoryEntry entry)
     {
         if (entry == null)
             throw new ArgumentNullException("entry");

         _entry = entry;
         _group = (IADsGroup)entry.NativeObject;
     }

     public DirectoryEntry Entry
     {
         get { return _entry; }
     }

     public IADsGroup NativeObject
     {
         get { return _group; }
     }

     #region IDisposable Members

     public void Dispose()
     {
         _entry.Dispose();
     }

     void IDisposable.Dispose()
     {
         Dispose();
     }

     #endregion
 }
}

Of course, we would also need to understand what a GroupType in AD really is:

using System;
using System.Collections.Generic;
using System.Text;

namespace AdLib
{
 [Flags]
 public enum GroupType : int
 {
     Unknown = 0,
     LocalDistribution = 4,
     LocalSecurity = (4 | -2147483648),
     GlobalDistribution = 2,
     GlobalSecurity = (2 | -2147483648),
     UniversalDistribution = 8,
     UniversalSecurity = (8 | -2147483648)
 }
}

In the next post, we will talk about domains and eventually how this all fits together.
