First, let's take a look at what is active directory. I don't need to describe it. I can refer to the following URL or search for the Active Directory keyword in the. NET Help document.

Next, let's look at the permissions. You can use "network neighbor -- entire network -- directory -- Demain (your domain name)" to view all information about the domain. You can see what is going on at a glance.
Users in all organizational units are in the users (container) -- demain users (group ).
UseCodeIf you are a domain administrator, you can perform any operations. Otherwise, you can only query user attributes.

Private void searchuser ()
{
String domainname = "Domain ";
String groupname = "Domain Users ";
String dirmemname = "";
// Obtain each user name in the Domain Users domain user
System. directoryservices. directoryentry group = new system. directoryservices. directoryentry ("winnt: //" + domainname + "/" + groupname + ", group ");
Foreach (Object member in (ienumerable) group. Invoke ("members "))
{
// Based on a large number of users, for example, "LDAP: // ou = software package, ou = System Development Department, ou = Information Service Department, ou = Operation Support Center, ou = XX Company, Dc = domain, Dc = com, Dc = cn"
System. directoryservices. directoryentry dirmem = new system. directoryservices. directoryentry (member );
Dirmemname = dirmem. Name;
String domainname = "Domain ";
String filterstr = "(samaccountname =" + dirmemname + ")";
System. directoryservices. directorysearcher findimethyl = new system. directoryservices. directorysearcher (domainname );
Findimethyl. Filter = filterstr;
System. directoryservices. searchresult findres = findimethyl. findone ();
System. directoryservices. directoryentry myuser = findres. getdirectoryentry ();
String oupath = myuser. Parent. path;
// Find the LDAP address of the user, log on to the domain administrator, and obtain the attributes of the user.
String strfieldsvalue = "", strfields = "";
System. directoryservices. directoryentry myds = new system. directoryservices. directoryentry (oupath, "Domain Administrator name", "domain administrator password ");
Foreach (system. directoryservices. directoryentry tempentry in myds. Children)
{
If (tempentry. schemaclassname. tostring () = "user" & tempentry. properties ["samaccountname"]. value. tostring (). tolower () = dirmemname)
{
Foreach (string propertyname in tempentry. properties. propertynames)
{
String onenode = propertyname + ":" +
Entry. properties [propertyname] [0]. tostring ();
This. textbox1.text = onenode;
}
}

-------------------------------------------

Public void adduser (string strpath, string username, string chinesename) // the organization to which the user is added by strpath, for example, "LDAP: // ou = XX Company, Dc = domain, dc = com "account, Chinese name {
Try
{
String rootdse;
// System. directoryservices. directorysearcher dsesearcher = new system. directoryservices. directorysearcher ();
// Rootdse = dsesearcher. searchroot. path;
// Rootdse = "LDAP: // dc = domain, Dc = com ";
// Rootdse = rootdse. insert (7, "cn = users ,");
System. directoryservices. directoryentry myde = new system. directoryservices. directoryentry (strpath );
System. directoryservices. directoryentries myentries = myde. Children;
// Create a new entry 'sample' in the container.
String strname = "cn =" + chinesename;
System. directoryservices. directoryentry mydirectoryentry = myentries. Add (strname, "user ");

// MessageBox. Show (mydirectoryentry. schemaclassname. tostring ());
Mydirectoryentry. properties ["userprincipalname"]. value = username;
Mydirectoryentry. properties ["name"]. value = chinesename;
Mydirectoryentry. properties ["samaccountname"]. value = username;
Mydirectoryentry. properties ["useraccountcontrol"]. value = 66048; // 590336;
Mydirectoryentry. commitchanges ();
}

Private void Addou (string strpath, string ouname) // Add the organizational unit to the organizational unit of the strpath. The organizational unit name.
{
Try
{
// String rootdse;
// System. directoryservices. directorysearcher dsesearcher = new system. directoryservices. directorysearcher ();
// Rootdse = dsesearcher. searchroot. path;
// Rootdse = "LDAP: // ou = Baiyi Fashion Plaza, Dc = domain, Dc = com ";

System. directoryservices. directoryentry myde = new system. directoryservices. directoryentry (strpath );
System. directoryservices. directoryentries myentries = myde. Children;
String name = "ou =" + ouname;
System. directoryservices. directoryentry mydirectoryentry = myentries. Add (name, "organizationalunit ");

Mydirectoryentry. properties ["name"]. value = ouname;
Mydirectoryentry. properties ["instancetype"]. value = 4;
Mydirectoryentry. properties ["distinguishedname"]. value = "ou =" + ouname + ", Dc = domain, Dc = com )";
Mydirectoryentry. properties ["objectcategory"]. value = "cn = organizational-unit, Cn = schema, Cn = configuration, Dc = sedep, Dc = com ";
Mydirectoryentry. properties ["ou"]. value = ouname;
Mydirectoryentry. properties ["postalcode"]. value = "777 ";

Mydirectoryentry. commitchanges ();
// Usermoveto ("LDAP: // ou =" + ouname + ", Dc = sedep, Dc = com", strpath );
}
