SiteIdentityPermission クラス

コードのダウンロード元の Web サイトに対して ID アクセス許可を定義します。このクラスは継承できません。

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

Visual Basic (宣言)

<SerializableAttribute> _
<ComVisibleAttribute(True)> _
Public NotInheritable Class
 SiteIdentityPermission
    Inherits CodeAccessPermission

Visual Basic (使用法)

Dim instance As SiteIdentityPermission

[SerializableAttribute] 
[ComVisibleAttribute(true)] 
public sealed class SiteIdentityPermission
 : CodeAccessPermission

C++

[SerializableAttribute] 
[ComVisibleAttribute(true)] 
public ref class SiteIdentityPermission sealed
 : public CodeAccessPermission

/** @attribute SerializableAttribute() */

 CodeAccessPermission

解説

このクラスを使用すると、呼び出し元が特定の Web サイトであることを確認できます。サイト ID は、HTTP、HTTPS、および FTP のプロトコルの付いた URL からのコードだけで定義されます。URL のプロトコルの後ろの "//" から次の "/" までの間に文字列がある場合は、その文字列がサイトを表します。たとえば、URL http://www.fourthcoffee.com/process/grind.htm の www.fourthcoffee.com がサイトです。ポート番号は除外されます。URL が http://www.fourthcoffee.com:8000/ の場合、サイトは www.fourthcoffee.com:8000 ではなく www.fourthcoffee.com になります。

サイトには、完全に一致する文字列か、ドット区切り文字の前にワイルドカード ("*") を付けた文字列を指定できます。たとえば、サイト名として文字列 *.fourthcoffee.com を指定すると、fourthcoffee.com と www.fourthcoffee.com の両方と一致します。ワイルドカードを使用しない場合は、正確に一致するサイト名だけが見つかります。サイト名として文字列 * を指定した場合、任意のサイトと一致しますが、サイト証明のないコードとは一致しません。

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。
