例

次の例は、 ProviderProtect メソッドの実装を示しています。 これは、 DataProtector クラスの大規模なコード例の一部です。

// To allow a service to hand out instances of a DataProtector we demand unrestricted DataProtectionPermission
// in the constructor, but Assert the permission when ProviderProtect is called.  This is similar to FileStream
// where access is checked at time of creation, not time of use.
[SecuritySafeCritical]
[DataProtectionPermission(SecurityAction.Assert, ProtectData = true)]
protected override byte[] ProviderProtect(byte[] userData)
{

    // Delegate to ProtectedData
    ProtectedMemory.Protect(userData, Scope);
    return userData;
}

' To allow a service to hand out instances of a DataProtector we demand unrestricted DataProtectionPermission 
' in the constructor, but Assert the permission when ProviderProtect is called.  This is similar to FileStream
' where access is checked at time of creation, not time of use.
<SecuritySafeCritical(), DataProtectionPermission(SecurityAction.Assert, ProtectData:=True)> _
Protected Overrides Function ProviderProtect(ByVal userData() As Byte) As Byte()

    ' Delegate to ProtectedData
    ProtectedMemory.Protect(userData, Scope)
    Return userData

End Function 'ProviderProtect
