Definition

Namespace:

System.Security.Cryptography.X509Certificates

Assembly:

System.Security.Cryptography.dll

Source:

X509ChainPolicy.cs

Gets a collection of object identifiers (OIDs) specifying which application policies or enhanced key usages (EKUs) the certificate must support.

public:
 property System::Security::Cryptography::OidCollection ^ ApplicationPolicy { System::Security::Cryptography::OidCollection ^ get(); };

public System.Security.Cryptography.OidCollection ApplicationPolicy { get; }

member this.ApplicationPolicy : System.Security.Cryptography.OidCollection

Public ReadOnly Property ApplicationPolicy As OidCollection

Property Value

OidCollection

An OidCollection object.

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.

//Output chain information of the selected certificate.
X509Chain ^ ch = gcnew X509Chain;
ch->ChainPolicy->RevocationMode = X509RevocationMode::Online;
ch->Build( certificate );
Console::WriteLine( "Chain Information" );
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 );

//Output chain information of the selected certificate.
X509Chain ch = new X509Chain();
ch.ChainPolicy.RevocationMode = X509RevocationMode.Online;
ch.Build (certificate);
Console.WriteLine ("Chain Information");
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);

'Output chain information of the selected certificate.
Dim ch As New X509Chain()
ch.ChainPolicy.RevocationMode = X509RevocationMode.Online
ch.Build(certificate)
Console.WriteLine("Chain Information")
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)

Remarks

By default, this collection is empty. You can add additional object identifiers (OIDs) to the collection using the following code:

X509Chain^ ch = gcnew X509Chain();
ch->ChainPolicy->ApplicationPolicy->Add(gcnew Oid("1.2.1.1"));

X509Chain ch = new X509Chain();
ch.ChainPolicy.ApplicationPolicy.Add(new Oid("1.2.1.1"));

Dim ch As new X509Chain()
ch.ChainPolicy.ApplicationPolicy.Add(new Oid("1.2.1.1"))
