How to use C # to add, delete, modify, and query users and organizational units in Active Directory

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.
Http://developer.ccidnet.com/pub/article/c322_a28703_p2.html

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 ).
When using code for access, if you are a domain administrator user, you can perform any operation. 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;
}
}

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 ");
