C#使用目录服务将用户添加到Active Directory，已启用属性不起作用

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

string adPath = "LDAP://yourdomain.com"; // Active Directory路径
string username = "admin"; // 管理员用户名
string password = "password"; // 管理员密码

DirectoryEntry directoryEntry = new DirectoryEntry(adPath, username, password);

DirectorySearcher directorySearcher = new DirectorySearcher(directoryEntry);
directorySearcher.Filter = "(objectClass=user)"; // 过滤条件，只搜索用户对象

SearchResultCollection searchResults = directorySearcher.FindAll();

foreach (SearchResult searchResult in searchResults)
{
    DirectoryEntry userEntry = searchResult.GetDirectoryEntry();
    // 根据需要判断用户是否已启用，如果已启用则跳过
    if ((int)userEntry.Properties["userAccountControl"].Value & 0x2 == 0x2)
    {
        continue;
    }
    
    // 设置用户属性
    userEntry.Properties["userAccountControl"].Value = (int)userEntry.Properties["userAccountControl"].Value & ~0x2; // 启用用户
    
    // 保存更改
    userEntry.CommitChanges();
}
