Create an example
Open Microsoft Visual Studio .NET and create a Visual C # Console application project. In the Solution Explorer, right-click the reference, and then click Add Reference. Add a reference to the System.DirectoryServices.dll assembly. Replace the code in the class1.cs to the following code: use system;
Using System.directoryServices;
Class class1
{
Static void main (string [] args)
{
Try
{
DirectoryEntry Ad = New DirectoryEntry ("Winnt: //"
Environment.machinename ", Computer");
DirectoryEntry newuser = ad.children.add ("testuser1", "user");
Newuser.invoke ("setPassword", new object [] {"# 12345abc"});
Newuser.invoke ("put", new object [] {"description", "test user from .net"});
Newuser.commitchanges ();
DirectoryEntry GRP;
Grp = ad.children.find ("Guests", "group");
IF (GRP! = null) {grp.invoke ("add", new object [] {newuser.path.tostring ()});
Console.writeline ("Account Created SuccessFully);
Console.readline ();
}
Catch (Exception EX)
{
Console.writeLine (ex.Message);
Console.readline ();
}
}
} Compile and run the project. In the following steps on Windows 2000-based computers, verify that the account has been created and added to the guest group:
From the start menu, point to the program, then point to Administrative Tools, and then click Computer Management. Click Local User and Group Nodes to expand. The new account will be displayed under the User Node and will appear under the node of the guest group. To follow the following steps on a Windows XP-based computer to verify that the account has been created and added to the guest group:
From the Start menu, click Control Panel. Double-click the user account. The new user account will be displayed in the User Account dialog box. Importantly, you should remove the newly created user account from the system after testing.

Code description
Creating a new directory entry When you create a directory item in this example, assume that the system is running Microsoft Windows NT, Windows 2000, or Windows XP. Pay attention
The DirectoryEntry constructor passes the string starting with "Winnt: //". You can also run "Directory Service" on other third-party operating systems. DirectoryEntry Ad = New DirectoryEntry ("Winnt: //" SystemInformation.computername ", Computer");
Add a directory tree to the catalog item below
Action added in the Active Directory tree
User type, value

DirectoryEntry.
DirectoryEntry newuser = ad.children.add ("testuser1", "user");
Set the password for the new user account and describe the following code call
INVOKE method to call
DirectoryEntry object
SetPassword and
PUT method. This will set a password for the user account and assign a description. This code is also called
The commitChanges method saves these changes.
Newuser.invoke ("setPassword", new object [] {"# 12345abc"});

Newuser.commitchanges ();
The first step in adding an account to a group to add an account to a group to define

The value returned by the Find method to determine if the group has been found. If you find the group, the new user account will be added to the group.
DirectoryEntry GRP;
Grp = ad.children.find ("Guests", "group");
IF (GRP! = null) {grp.invoke ("add", new object [] {newuser.path.tostring ()});
