X509Chain Constructor (Boolean)

 

Initializes a new instance of the X509Chain class specifying a value that indicates whether the machine context should be used.

Namespace:   System.Security.Cryptography.X509Certificates
Assembly:  System (in System.dll)

public:
[SecurityCriticalAttribute]
X509Chain(
	bool useMachineContext
)

Parameters

useMachineContext
Type: System::Boolean

true to use the machine context; false to use the current user context.

This constructor can be used when the user profile is not loaded and the machine context needs to be used. When the useMachineContext parameter is set to true, the local machine context (HCCE_LOCAL_MACHINE flag) is used to create the chain. If the parameter is set to false, the current user context (HCCE_CURRENT_USER flag) is used.

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.

//Output chain information of the selected certificate.
X509Chain ^ ch = gcnew 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 );
