如何ping SSLStream

Question

我有一个Tcp客户端服务器，当客户端和服务器之间的功能完成时，我添加了一个SSLstream用于连接

客户：

public void ReceiveMessage()
    {
        var clientCertificate = new X509Certificate2(ClientCertificateFile, ClientCertificatePassword);
        var clientCertificateCollection = new X509CertificateCollection(new X509Certificate[] { clientCertificate });
        string ServerCertificateName = "MyServer";

        sslStream = new SslStream(this.GetStream(), false, App_CertificateValidation);
        sslStream.AuthenticateAsClient(ServerCertificateName, clientCertificateCollection, SslProtocols.Tls12, false);

        while (!SLLConnectionSuccess)
        {
            if (sslStream.IsAuthenticated)
            {
                SLLConnectionSuccess = true;
                break;
            }
        }
        while (!ClosedThreads)
        {
            byte[] buffer = new byte[1];
            int bytes = -1;
            try
            {

                bytes = sslStream.Read(buffer, 0, buffer.Length);
                //Actions..
            }
            catch()
            {
            }
        }
    }

服务器：

public void Process() 
    {

        Stream = client.GetStream();

        using (var sslStream = new SslStream(Stream, false, App_CertificateValidation))
        {
            sslStream.AuthenticateAsServer(serverCertificate, true, SslProtocols.Tls12, false);
            sslstream = sslStream;

            while (true)
            {
                byte[] buffer = new byte[1];
                try
                { 
                    sslStream.Read(buffer, 0, buffer.Length);

                   //Actions
                }
                catch(System.IO.IOException e)
                {
                }
                Thread.Sleep(5);
            }
        }
    }

当服务器崩溃并且客户端理解并终止连接时，我无法解决问题。使用TCP时，我使用了ping，但是在这里不起作用。我将不胜感激。
