The X509ChainPolicy object associated with this X.509 chain.

Examples

The following code example opens the current user's personal certificate store, allows you to select a certificate, then writes certificate and certificate chain information to the console. The output depends on the certificate you select.

C++

Copy


		//Output chain information of the selected certificate.
		X509Chain ch = new X509Chain();
		ch.Build (certificate);
		Console.WriteLine ("Chain Information");
		ch.ChainPolicy.RevocationMode = X509RevocationMode.Online;
		Console.WriteLine ("Chain revocation flag: {0}", ch.ChainPolicy.RevocationFlag);
		Console.WriteLine ("Chain revocation mode: {0}", ch.ChainPolicy.RevocationMode);
		Console.WriteLine ("Chain verification flag: {0}", ch.ChainPolicy.VerificationFlags);
		Console.WriteLine ("Chain verification time: {0}", ch.ChainPolicy.VerificationTime);
		Console.WriteLine ("Chain status length: {0}", ch.ChainStatus.Length);
		Console.WriteLine ("Chain application policy count: {0}", ch.ChainPolicy.ApplicationPolicy.Count);
		Console.WriteLine ("Chain certificate policy count: {0} {1}", ch.ChainPolicy.CertificatePolicy.Count, Environment.NewLine);
