示例1: ValidateChain
ValidationResult ValidateChain (string host, bool server, X509Certificate leaf,
X509Chain chain, X509CertificateCollection certs,
SslPolicyErrors errors)
{
var oldChain = chain;
var ownsChain = chain == null;
try {
var result = ValidateChain (host, server, leaf, ref chain, certs, errors);
if (chain != oldChain)
ownsChain = true;
return result;
} finally {
// If ValidateChain() changed the chain, then we need to free it.
if (ownsChain && chain != null)
chain.Dispose ();
}

AcquireCredentials - Attempts to find Client Credential
Information, that can be sent to the server. In our case,
this is only Client Certificates, that we have Credential Info.
How it works:
case 0: Cert Selection delegate is present
Always use its result as the client cert answer.
Try to use cached credential handle whenever feasible.
Do not use cached anonymous creds if the delegate has returned null
and the collection is not empty (allow responding with the cert later).
case 1: Certs collection is empty
Always use the same statically acquired anonymous SSL Credential
case 2: Before our Connection with the Server
If we have a cached credential handle keyed by first X509Certificate
**content** in the passed collection, then we use that cached
credential and hoping to restart a session.
Otherwise create a new anonymous (allow responding with the cert later).
case 3: After our Connection with the Server (i.e. during handshake or re-handshake)
The server has requested that we send it a Certificate then
we Enumerate a list of server sent Issuers trying to match against
our list of Certificates, the first match is sent to the server.
Once we got a cert we again try to match cached credential handle if possible.
This will not restart a session but helps minimizing the number of handles we create.
In the case of an error getting a Certificate or checking its private Key we fall back
to the behavior of having no certs, case 1.
Returns: True if cached creds were used, false otherwise.
