指定应使用哪些证书建立安全套接字层（SSL）连接。

public:
 property System::Security::Cryptography::X509Certificates::X509CertificateCollection ^ ClientCertificates { System::Security::Cryptography::X509Certificates::X509CertificateCollection ^ get(); };
public System.Security.Cryptography.X509Certificates.X509CertificateCollection ClientCertificates { get; }
member this.ClientCertificates : System.Security.Cryptography.X509Certificates.X509CertificateCollection
Public ReadOnly Property ClientCertificates As X509CertificateCollection

属性值

X509CertificateCollection

包含 X509CertificateCollection一个或多个客户端证书的客户端证书。 默认值派生自配置文件中的邮件配置属性。

示例

下面的代码示例建立与 SMTP 服务器的 SSL 连接，并使用连接发送电子邮件。

public static void CreateTestMessage(string server)
{
    string to = "jane@contoso.com";
    string from = "ben@contoso.com";
    MailMessage message = new MailMessage(from, to);
    message.Subject = "Using the new SMTP client.";
    message.Body = @"Using this new feature, you can send an email message from an application very easily.";
    SmtpClient client = new SmtpClient(server);
    // Credentials are necessary if the server requires the client
    // to authenticate before it will send email on the client's behalf.
    client.UseDefaultCredentials = true;
                client.EnableSsl = true;
    client.Send(message);
}

注解

默认情况下，客户端证书是可选的;但是，服务器配置可能需要客户端在初始连接协商过程中提供有效的证书。

注释

框架在创建 SSL 会话时缓存 SSL 会话，并尝试尽可能为新请求重复使用缓存会话。 尝试重复使用 SSL 会话时，框架使用第一个元素 ClientCertificates （如果有），或者尝试重复使用匿名会话（如果 ClientCertificates 为空）。
