C# 创建Group Object in Active Directory的代码

把做工程过程中重要的内容段备份一次，如下内容段是关于C# 创建Group Object in Active Directory的内容，希望能对码农有一些用途。

using System.DirectoryServices;
using System.Reflection;

public class ADGroup
{

private String ADGRPOUP = "group";

enum GrpType : uint
{
UnivGrp = 0x08,
DomLocalGrp = 0x04,
GlobalGrp = 0x02,
SecurityGrp = 0x80000000
}

String str = (String)ent.Properties["defaultNamingContext"][0];
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["sAMAccountName"].Add("myGroupName");
group.Properties["description"].Add(" description myGroupName");
group.Properties["groupType"].Add(typeNum);
group.CommitChanges();
}
