Příklady

Následující příklad ukazuje implementaci ProviderProtect metody . Je součástí většího příkladu DataProtector kódu pro třídu .

// 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;
}
