Definizione

Spazio dei nomi:

System

Assembly:

System.Runtime.dll

Assembly:

System.Runtime.Extensions.dll

Assembly:

mscorlib.dll

Assembly:

netstandard.dll

Restituisce un valore che indica se il dominio applicazione è quello predefinito per il processo.

public:
 bool IsDefaultAppDomain();

public bool IsDefaultAppDomain ();

member this.IsDefaultAppDomain : unit -> bool

Public Function IsDefaultAppDomain () As Boolean

Restituisce

Boolean

true se l'oggetto AppDomain corrente rappresenta il dominio applicazione predefinito per il processo. In caso contrario, false.

Esempio

Nell'esempio di codice seguente viene creato un secondo dominio applicazione e vengono visualizzate informazioni sul dominio predefinito e sul nuovo dominio.

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() );
}

// in the global assembly cache should be shared across multiple

    ShowDomainInfo();

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

Commenti

Ogni processo gestito ha un dominio applicazione predefinito. L'esecuzione inizia nel dominio predefinito.
