Question

Is there any sample that deletes computer account from AD using C#?

I have searched many sources, but all are about user account.

added my code here, i always got errors for some reason.

public static bool checkExistingPC(string compName,string userName,string userPwd )
{
    try
    {
        DirectoryEntry entry = new DirectoryEntry("LDAP://test.com",userName,userPwd,AuthenticationTypes.Secure);
        DirectorySearcher mySearcher = new DirectorySearcher(entry);
       mySearcher.Filter = "(&(objectClass=computer)(|(cn=" + compName + ")(dn=" + compName + ")))";
       foreach (SearchResult result in mySearcher.FindAll())
       {
           if (result != null)
           {

               MessageBox.Show("computer GetDirectoryEntry():" + result.Path+"\n"+"computer path: "+result.Path);
                DirectoryEntry entryToRemove = new DirectoryEntry(result.Path,userName,userPwd);
                 entry.Children.Remove(entryToRemove);

               return true;
           }
           else
           {
               return false;
           }
       }
    }
    catch (Exception e)
    {
        MessageBox.Show(e.Message);
    }
    return false;
}

Using ADSI which is under System.DirectoryServices use a commit mechanism, here is a working sample :

/* Retreiving RootDSE infos
 */
string ldapBase = "LDAP://WM2008R2ENT:389/";
string sFromWhere = ldapBase + "rootDSE";
DirectoryEntry root = new DirectoryEntry(sFromWhere, "dom\\jpb", "PWD");
string defaultNamingContext = root.Properties["defaultNamingContext"][0].ToString();

/* Retreiving the computer to remove
 */
sFromWhere = ldapBase + defaultNamingContext;
DirectoryEntry deBase = new DirectoryEntry(sFromWhere, "dom\\jpb", ".biènèsph^r^.1966");

DirectorySearcher dsLookForDomain = new DirectorySearcher(deBase);
dsLookForDomain.Filter = "(&(cn=MACHSUPR))"; // MACHSUPR is the computer to delete
dsLookForDomain.SearchScope = SearchScope.Subtree;
dsLookForDomain.PropertiesToLoad.Add("cn");
dsLookForDomain.PropertiesToLoad.Add("distinguishedName");

SearchResultCollection srcComputer = dsLookForDomain.FindAll();

foreach (SearchResult aComputer in srcComputer)
{
  /* For each computer
   */
  DirectoryEntry computerToDel = aComputer.GetDirectoryEntry();
  computerToDel.DeleteTree();
  computerToDel.CommitChanges();
}
