member this.Id : int
Public ReadOnly Property Id As Integer
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();
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.
//
[LoaderOptimizationAttribute(LoaderOptimization::MultiDomainHost)]
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 ) );
