DirectoryEntry对象在C#中用于操作和管理目录服务(也称为Active Directory)中的目录项。下面是一些常用的DirectoryEntry对象的使用方法:
创建一个DirectoryEntry对象:DirectoryEntry entry = new DirectoryEntry("LDAP://servername/ou=users,dc=example,dc=com", "admin", "password");获取目录项的属性:string username = entry.Properties["sAMAccountName"].Value.ToString();string email = entry.Properties["mail"].Value.ToString();修改目录项的属性:entry.Properties["displayName"].Value = "John Doe";entry.CommitChanges();添加新的目录项:DirectoryEntry newUser = entry.Children.Add("CN=New User", "user");newUser.Properties["sAMAccountName"].Value = "newuser";newUser.Properties["givenName"].Value = "New";newUser.Properties["sn"].Value = "User";newUser.Properties["userPrincipalName"].Value = "newuser@example.com";newUser.CommitChanges();删除目录项:entry.Children.Remove("CN=New User");枚举子目录项:foreach (DirectoryEntry child in entry.Children){Console.WriteLine(child.Name);}以上是一些常用的DirectoryEntry对象的使用示例。请注意,使用DirectoryEntry对象操作Active Directory时需要相应的权限。
