从C-Sharp/C上的Active Directory获取用户帐户状态(已锁定/已解锁)

using System;
using System.DirectoryServices;
using System.DirectoryServices.AccountManagement;

public class ActiveDirectoryHelper
{
    public static bool IsAccountLocked(string username)
    {
        using (var context = new PrincipalContext(ContextType.Domain))
        {
            using (var user = UserPrincipal.FindByIdentity(context, IdentityType.SamAccountName, username))
            {
                if (user == null)
                {
                    throw new ArgumentException("User not found in Active Directory.");
                }

                return user.IsAccountLockedOut();
            }
        }
    }
}
