C# - Check For Groups A User Is A Member Of

i have the code to get the members of a local group example administrators

private void GetUserGrps()
{
using (DirectoryEntry groupEntry = new DirectoryEntry("WinNT://./Administrators,group"))
{
foreach (object member in (IEnumerable)groupEntry.Invoke("Members"))
{
using (DirectoryEntry memberEntry = new DirectoryEntry(member))
{
new GUIUtility().LogMessageToFile(memberEntry.Path);
}
}
}

Is there a way to get the groups a local user belongs to using directory services?

without using activedirectory or domain in it because i want for the local machine only and not for a domain.
