NetCodeGroup(IMembershipCondition) コンストラクター

定義

NetCodeGroup クラスの新しいインスタンスを初期化します。

public:
 NetCodeGroup(System::Security::Policy::IMembershipCondition ^ membershipCondition);
public NetCodeGroup (System.Security.Policy.IMembershipCondition membershipCondition);
new System.Security.Policy.NetCodeGroup : System.Security.Policy.IMembershipCondition -> System.Security.Policy.NetCodeGroup
Public Sub New (membershipCondition As IMembershipCondition)

パラメーター

membershipCondition
IMembershipCondition

このコード グループがコード アクセスのセキュリティ ポリシーに適用されるかどうかを判断するために証拠をテストするメンバーシップ条件。

例外

membershipCondition パラメーターが null です。

membershipCondition パラメーターの型が有効ではありません。

次のコード例では、 を作成し、HTTP スキームを NetCodeGroup 使用してダウンロードしたコードのオブジェクトを追加 CodeConnectAccess する方法を示します。
