安全服务器没有收到我发送的内容

Question

我正在尝试通过Windows上的 TLS 1 连接到服务器。

这是我连接服务器的方式

public void Connect(string hostName, int port)
    {
        this.tcpClient.Client.Connect(hostName, port);

        RemoteCertificateValidationCallback validationCallback = new RemoteCertificateValidationCallback(ServerValidationCallback);
        LocalCertificateSelectionCallback selectionCallback = new LocalCertificateSelectionCallback(ClientCertificateSelectionCallback);
        EncryptionPolicy encryptionPolicy = EncryptionPolicy.RequireEncryption;

        this.sslStream = new SslStream(this.tcpClient.GetStream(), true, validationCallback, selectionCallback, encryptionPolicy);

        //handshake 
        X509CertificateCollection clientCertificates = GetCertificates();

        this.sslStream.AuthenticateAsClient(hostName);
        //this.sslStream.AuthenticateAsClient(hostName, clientCertificates, SslProtocols.Tls, true);
    }

比我通过方法发送消息

this.sslStream.Write(messageBytes);
this.sslStream.Flush();
this.tcpClient.GetStream().Flush();

服务器没有收到我的任何信息。
