An integer that identifies the application domain.

The following code example creates a second application domain and displays information about the default domain and the new domain.

using namespace System;
using namespace System::Reflection;

// This method has the same signature as the CrossAppDomainDelegate,
// so that it can be executed easily in the new application domain.
static void ShowDomainInfo()
    AppDomain^ ad = AppDomain::CurrentDomain;
    Console::WriteLine( L"FriendlyName: {0}", ad->FriendlyName );
    Console::WriteLine( L"Id: {0}", ad->Id );
    Console::WriteLine( L"IsDefaultAppDomain: {0}", ad->IsDefaultAppDomain() );

// The following attribute indicates to the loader that assemblies
// in the global assembly cache should be shared across multiple 
// application domains.
int main()
    // Show information for the default application domain.

    // Create a new application domain and display its information.
    AppDomain^ newDomain = AppDomain::CreateDomain( L"MyMultiDomain" );
    newDomain->DoCallBack( gcnew CrossAppDomainDelegate( ShowDomainInfo ) );

    return 0;
