Examples
The following code shows the use of the FirstMatchCodeGroup constructor. This code example is part of a larger example provided for FirstMatchCodeGroup class.
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")
namedPermissions.AddPermission(rootFilePermissions)
' 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, _
policy)
Remarks
This constructor creates a basic code group and should be called from the constructors of custom code groups. Child code groups can be added using the AddChild method.
