C#: Getting members of a group the easy way with .Net 3.5 (Discussion groups, nested, recursive, security groups, etc.)
Just saw this being discussed internally and thought that it was quite useful to a lot of you out there so I thought I'd share. The true boolean to grp.GetMembers tells it to recursively get the nested group members too. I tested this out on discussion groups, security groups, with users and computers and works as expected.

groupName = args[0];
domainName = args[1];
PrincipalContext ctx = new PrincipalContext(ContextType.Domain, domainName);
GroupPrincipal grp = GroupPrincipal.FindByIdentity(ctx, IdentityType.Name, groupName);
if (grp != null)
{
foreach (Principal p in grp.GetMembers(true))
{
Console.WriteLine(p.Name); //You can add more attributes, samaccountname, UPN, DN, object type, etc...
}
grp.Dispose();
ctx.Dispose();
}
else
{
Console.WriteLine("\nWe did not find that group in that domain, perhaps the group resides in a different domain?");
}
}
}
}
