How to get all supported ldap controls in .Net C#

Question

I want to know is there any api provided in .Net to get all supported ldap controls for given domain ? In 'Ldp' utility when we bind to certain domain we get to see all supported ldap controls OID. I want this list through .Net. Or is it possible that check if certain ldap control is supported when OID of control is provided.

There's documentation that tells you which LDAP controls are supported:

I got answer from one of the stackoverflow thread. iPlanet LDAP and C# PageResultRequestControl

LdapConnection lc = new LdapConnection("ldap.server.name");
// Reading the Root DSE can always be done anonymously, but the AuthType
// must be set to Anonymous when connecting to some directories:
lc.AuthType = AuthType.Anonymous;
using (lc)
{
  // Issue a base level search request with a null search base:
  SearchRequest sReq = new SearchRequest(
    null,
    "(objectClass=*)",
    SearchScope.Base,
    "supportedControl");
  SearchResponse sRes = (SearchResponse)lc.SendRequest(sReq);
  foreach (String supportedControlOID in
    sRes.Entries[0].Attributes["supportedControl"].GetValues(typeof(String)))
  {
    Console.WriteLine(supportedControlOID);
  }
}
