'Usage

Dim instance As X509RevocationMode

'Declaration

Public Enumeration X509RevocationMode

Members

	Member name	Description
	NoCheck	No revocation check is performed on the certificate.
	Online	A revocation check is made using an online certificate revocation list (CRL).
	Offline	A revocation check is made using a cached certificate revocation list (CRL).

Remarks

This enumeration is used to specify whether a revocation check occurs and if it is performed online or offline.

Examples

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

C++

JScript

'Output chain information of the selected certificate.
Dim ch As 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)
