Question

I’m new to C# development.

In PHP we use

stream_socket_enable_crypto($fp, true, STREAM_CRYPTO_METHOD_TLS_CLIENT);

What is its equivalent in C#?

Answer 1

SSLStream appears to do what you want

var tcp = new TcpClient(machineName,443);
var ssl = new SslStream(tcp.GetStream);

You can specify a callback for doing certification validation. Otherwise it appears to default to the system’s policy ( which I believe is what I.E. also uses by default)
