Przykłady

Poniższy kod przedstawia użycie konstruktora FirstMatchCodeGroup . Ten przykład kodu jest częścią większego przykładu udostępnionego dla FirstMatchCodeGroup klasy.

FileIOPermission^ rootFilePermissions =
   gcnew FileIOPermission( PermissionState::None );
rootFilePermissions->AllLocalFiles = FileIOPermissionAccess::Read;
rootFilePermissions->SetPathList( FileIOPermissionAccess::Read, L"C:\\" );

// Add a permission to a named permission set.
NamedPermissionSet^ namedPermissions =
   gcnew NamedPermissionSet( L"RootPermissions" );
namedPermissions->AddPermission( rootFilePermissions );

// Create a PolicyStatement with exclusive rights to the policy.
PolicyStatement^ policy = gcnew PolicyStatement(
   namedPermissions,PolicyStatementAttribute::Exclusive );

// Create a FirstMatchCodeGroup with a membership condition that
// matches all code, and an exclusive policy.
FirstMatchCodeGroup^ codeGroup = gcnew FirstMatchCodeGroup(
   gcnew AllMembershipCondition,policy );

FileIOPermission rootFilePermissions =
    new FileIOPermission(PermissionState.None);
rootFilePermissions.AllLocalFiles = FileIOPermissionAccess.Read;
rootFilePermissions.SetPathList(FileIOPermissionAccess.Read,"C:\\");

// Add a permission to a named permission set.
NamedPermissionSet namedPermissions =
    new NamedPermissionSet("RootPermissions");
namedPermissions.AddPermission(rootFilePermissions);

// Create a PolicyStatement with exclusive rights to the policy.
PolicyStatement policy = new PolicyStatement(
    namedPermissions,PolicyStatementAttribute.Exclusive);

// Create a FirstMatchCodeGroup with a membership condition that
// matches all code, and an exclusive policy.
FirstMatchCodeGroup codeGroup =
    new FirstMatchCodeGroup(
    new AllMembershipCondition(),
    policy);

Dim rootFilePermissions As New FileIOPermission(PermissionState.None)
rootFilePermissions.AllLocalFiles = FileIOPermissionAccess.Read
rootFilePermissions.SetPathList(FileIOPermissionAccess.Read, "C:\\")

' Add a permission to a named permission set.
Dim namedPermissions As New NamedPermissionSet("RootPermissions")

' Create a PolicyStatement with exclusive rights to the policy.
Dim policy As New PolicyStatement( _
    namedPermissions, _
    PolicyStatementAttribute.Exclusive)

' Create a FirstMatchCodeGroup with a membership condition that 
' matches all code, and an exclusive policy.
Dim codeGroup As New FirstMatchCodeGroup( _
    New AllMembershipCondition, _
