Esempio

L'esempio seguente illustra l'uso di GacIdentityPermissionAttribute.

// To run this sample you must create a strong-name key named snkey.snk 
// using the Strong Name tool (sn.exe).  Both the library assembly and the 
// application assembly that calls it must be signed with that key.  
// To run successfully, the application assembly must be in the global 
// assembly cache.
// This console application can be created using the following code.

//#using <mscorlib.dll>
//#using <ClassLibrary1.dll>
//using namespace System;
//using namespace System::Security;
//using namespace System::Reflection;
//using namespace ClassLibrary1;
//[assembly: AssemblyVersion(S"1.0.555.0")]
//[assembly: AssemblyKeyFile(S"snKey.snk")];
//int main()
//{ 
//    try
//    {
//        Class1* myLib = new Class1();
//        myLib->DoNothing();
//
//        Console::WriteLine(S"Exiting the sample.");
//    }
//    catch (Exception* e)
//    {
//        Console::WriteLine(e->Message);
//    }
//}

Commenti

Questa classe viene usata per assicurarsi che i chiamanti siano registrati nella Global Assembly Cache (GAC).

L'ambito della dichiarazione consentita dipende dal SecurityAction valore utilizzato.

Le informazioni di sicurezza dichiarate da un attributo di sicurezza vengono archiviate nei metadati della destinazione dell'attributo e accedono al sistema in fase di esecuzione. Gli attributi di sicurezza vengono usati solo per la sicurezza dichiarativa. Per la sicurezza imperativa, usare la classe di autorizzazione corrispondente, GacIdentityPermission.

Per altre informazioni sull'uso degli attributi, vedere Attributi.
