如何在c#中验证active directory管理员用户？

using System.DirectoryServices;

string domainPath = "LDAP://yourdomain.com"; // Active Directory域路径
string username = "adminusername"; // 管理员用户名
string password = "adminpassword"; // 管理员密码

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

DirectorySearcher directorySearcher = new DirectorySearcher(directoryEntry);
directorySearcher.Filter = "(samAccountName=username)"; // 替换为要验证的用户名
directorySearcher.PropertiesToLoad.Add("memberOf"); // 可选，加载用户所属的组信息

SearchResult searchResult = directorySearcher.FindOne();

if (searchResult != null)
{
    // 用户存在，进行验证逻辑
    // ...
}
else
{
    // 用户不存在或验证失败
    // ...
}
