I know how to create groups, the problem is that I need to create Groups with diffrent scopes.
For example:
or Distribution, Global
I have found the code, but I dont understand the "enum" part.
How to join two enums if I want the group (for example) to be global+security.
or: Universal+distribution.
I tried many things, but I couldnt get the proper results.

Thx for help!

using System.DirectoryServices;
using System.Reflection;

public class ADGroup

   private String ADGRPOUP = "group";

   // Grouptype-Definition 
   enum GrpType : uint
      UnivGrp = 0x08,
      DomLocalGrp = 0x04,
      GlobalGrp = 0x02,
      SecurityGrp = 0x80000000

   DirectoryEntry ent = new DirectoryEntry("LDAP://RootDSE");
   String str = (String)ent.Properties["defaultNamingContext"][0];
   deAD = new DirectoryEntry("LDAP://" + str);
   GrpType gt = GrpType.GlobalGrp | GrpType.SecurityGrp;
   int typeNum = (int)gt; 
   DirectoryEntry ou = deAD.Children.Find("OU=Users");
   DirectoryEntry group = ou.Children.Add("cn=myGroupName", ADGRPOUP );
   group.Properties["description"].Add(" description myGroupName");
