C#提供了 LdapConnection 类用于连接Microsoft Active Directory 域服务或 LDAP 服务器的 TCP/IP 或 UDP LDAP 连接。
LdapConnection 类 LdapConnection 类创建与 Microsoft Active Directory 或 LDAP 服务器的 TCP/IP 或 UDP LDAP 连接。命名空间: System.DirectoryServices.Protocols
程序集: System.DirectoryServices.Protocols（在
system.directoryservices.protocols.dll 中）
public class LdapConnection : DirectoryConnection, IDisposable
下面是连接 Ldap的连接方法和大家分享下： 1 static LdapConnectionldapConnection; 2 static string ldapServer; 3 static NetworkCreden C#提供了 LdapConnection 类用于连接Microsoft Active Directory 域服务或 LDAP 服务器的 TCP/IP 或 UDP LDAP 连接。

23
ldapConnection.AuthType = AuthType.Basic;
24
ldapConnection.Credential = credential;

try
27

28
Console.WriteLine("链接.");
29
ldapConnection.Bind();
30
Console.WriteLine("链接成功");
31

}
33
catch (Exception ee)
34
{
35
Console.WriteLine(ee.Message);
36
}

ldapConnection.Dispose();

}
注意
如果我们使用ldapConnection.AuthType = AuthType.Anonymous; 的认证方式，就一定要让Dn与Pwd为空，实现匿名认证方式，如：
credential = new NetworkCredential(String.Empty, String.Empty);
