PublisherIdentityPermission コンストラクタ (PermissionState)

PermissionState を指定して、PublisherIdentityPermission クラスの新しいインスタンスを初期化します。

名前空間: System.Security.Permissions
アセンブリ: mscorlib (mscorlib.dll 内)
構文構文

Visual Basic (宣言)
Public Sub New ( _
    state As PermissionState _
)
Visual Basic (使用法)
Dim state As PermissionState

Dim instance As New PublisherIdentityPermission(state)
C#
public PublisherIdentityPermission (
    PermissionState state
)
C++
public:
PublisherIdentityPermission (
    PermissionState state
)
J#
public PublisherIdentityPermission (
    PermissionState state
)
JScript
public function PublisherIdentityPermission
 (
    state : PermissionState
)

パラメータ

state

PermissionState 値の 1 つ。

例外例外
例外の種類条件

ArgumentException

state パラメータが、PermissionState の有効値ではありません。

解説解説

完全に制限した (None) アクセス許可または Unrestricted アクセス許可のいずれかを作成します。

メモメモ

.NET Framework Version 1.0 および 1.1 では、アクセス許可状態値 Unrestricted を ID アクセス許可に割り当てることはできません。.NET Framework Version 2.0 では、任意のアクセス許可状態値を ID アクセス許可に割り当てることができます。つまり、バージョン 2.0 では、ID アクセス許可の動作が、IUnrestrictedPermission インターフェイスを実装しているアクセス許可の動作と等しくなります。バージョン 2.0 のアプリケーションをバージョン 1.1 の CAS ポリシーで実行する方法については、「<legacyV1CASPolicy> 要素」を参照してください。

使用例使用例
Visual Basic
publisherPerm = New PublisherIdentityPermission(PermissionState.None)
C#
publisherPerm = new PublisherIdentityPermission(PermissionState.None);
C++
*publisherPerm = gcnew PublisherIdentityPermission( PermissionState::None );
J#
publisherPerm = 
    new PublisherIdentityPermission(PermissionState.None);

PublisherIdentityPermission コンストラクタ (X509Certificate)

Authenticode X.509v3 証明書を指定して、PublisherIdentityPermission クラスの新しいインスタンスを初期化します。

名前空間: System.Security.Permissions
アセンブリ: mscorlib (mscorlib.dll 内)
構文構文

Visual Basic (宣言)
Public Sub New ( _
    certificate As X509Certificate _
)
Visual Basic (使用法)
Dim certificate As X509Certificate

Dim instance As New PublisherIdentityPermission(certificate)
C#
public PublisherIdentityPermission (
    X509Certificate certificate

)
J#
public PublisherIdentityPermission (
    X509Certificate certificate
)
JScript
public function PublisherIdentityPermission
 (
    certificate : X509Certificate
)

パラメータ

certificate

ソフトウェア発行元の ID を表す X.509 証明書。

例外例外
例外の種類条件

ArgumentNullException

certificate パラメータが null 参照 (Visual Basic では Nothing) です。

ArgumentException

certificate パラメータが有効な証明書ではありません。

解説解説

X.509 証明書は、指定したソフトウェア発行元の ID を Authenticode コードの署名で証されているとおりに定義します。

使用例使用例

PublisherIdentityPermission コンストラクタを使用する方法を次のコード例に示します。このコード例は、下記の例の一部です。

Visual Basic
Dim certPath = ("Publisher.cer")

' Create evidence for the Publisher.cer certificate.
Dim publisher As New Publisher(
 _
    X509Certificate.CreateFromCertFile(certPath))

Dim evidence As New Evidence
evidence.AddHost(publisher)

' Create an identity permission based on publisher evidence.
Dim x509Permission As New
 PublisherIdentityPermission( _
PermissionState.None)
x509Permission = publisher.CreateIdentityPermission(evidence)

' Verify that callers higher in the stack have been granted 
' permission.
x509Permission.Demand()
C#
string certPath = ("Publisher.cer");

// Create evidence for the Publisher.cer certificate.
Publisher publisher =
    new Publisher(X509Certificate.CreateFromCertFile(certPath));
Evidence evidence = new Evidence();
evidence.AddHost(publisher);

// Create an identity permission based on publisher evidence.
PublisherIdentityPermission x509Permission =
    (PublisherIdentityPermission)publisher.
    CreateIdentityPermission(evidence);

// Verify that callers higher in the stack have been granted 
// permission.
x509Permission.Demand();
C++
String^ certPath = "Publisher.cer";

// Create evidence for the Publisher.cer certificate.
Publisher^ publisher =
    gcnew Publisher(X509Certificate::CreateFromCertFile(certPath));
Evidence^ evidence = gcnew Evidence();
evidence->AddHost(publisher);

// Create an identity permission based on publisher evidence.
PublisherIdentityPermission^ x509Permission =
    (PublisherIdentityPermission^)
    publisher->CreateIdentityPermission(evidence);

// Verify that callers higher in the stack have been granted 
// permission.
x509Permission->Demand();
J#
String certPath = "Publisher.cer";
// Create evidence for the Publisher.cer certificate.
Publisher publisher = new Publisher(X509Certificate.
    CreateFromCertFile(certPath));
Evidence evidence = new Evidence();
evidence.AddHost(publisher);
// Create an identity permission based on publisher evidence.
PublisherIdentityPermission x509Permission 
    = (PublisherIdentityPermission)(
    publisher.CreateIdentityPermission(evidence));
// Verify that callers higher in the stack have been granted 
// permission.
x509Permission.Demand();
