Question

我使用以下代码连接到主机：

protected bool OpenSocket(string hostIPAddress, int hostIPPort)
{
    try
    {
        if ((this._tcpSocket != null) && (this._tcpSocket.Connected == true))
            return (true);
    }
    catch { }

    // Reset variables
    this._isSocketOpen = false;
    this._isSSLOpen = false;

    string ipAddress = this.GetHostIPAddress(hostIPAddress);
    this._tcpSocket = new TcpClient(ipAddress, hostIPPort);
    this._tcpipConnectionStream = this._tcpSocket.GetStream();
    this._isSocketOpen = true;
    return true;
}

连接主机时有没有办法确定SSL连接类型（即SSL2，SSL3，TL1.2）？我研究过这样的事情：

SslStream sslStream = new SslStream(this._tcpSocket.GetStream(), false, new RemoteCertificateValidationCallback(ValidateServerCertificate), null);
sslStream.AuthenticateAsClient(hostIPAddress);

但是我认为那将是设置SSL协议不是它，而不是获取它？我很失落。

您可以通过查询SslProtocol类型的SslStream属性来检查连接类型。

SslStream sslStream = new SslStream(this._tcpSocket.GetStream(), false, new RemoteCertificateValidationCallback(ValidateServerCertificate), null);
sslStream.AuthenticateAsClient(hostIPAddress);
Console.WriteLine(sslStream.SslProtocol);

此属性将返回Enumeration的值 SslProtocols
