AppDomain.IsDefaultAppDomain AppDomain.IsDefaultAppDomain AppDomain.IsDefaultAppDomain AppDomain.IsDefaultAppDomain Method

Definition

Returns a value that indicates whether the application domain is the default application domain for the process.

public:
 bool IsDefaultAppDomain();
public bool IsDefaultAppDomain ();
member this.IsDefaultAppDomain : unit -> bool
Public Function IsDefaultAppDomain () As Boolean

Returns

true if the current AppDomain object represents the default application domain for the process; otherwise, false.

Examples

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.
    ShowDomainInfo();

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

    return 0;
}

using System;
using System.Reflection;

public class Example
{
    // The following attribute indicates to the loader that assemblies
    // in the global assembly cache should be shared across multiple 
    // application domains.

    public static void Main()
    {
        // Show information for the default application domain.
        ShowDomainInfo();

        // Create a new application domain and display its information.
        AppDomain newDomain = AppDomain.CreateDomain("MyMultiDomain");
        newDomain.DoCallBack(new CrossAppDomainDelegate(ShowDomainInfo));
    }

    // This method has the same signature as the CrossAppDomainDelegate,
    // so that it can be executed easily in the new application domain.
    //

        AppDomain ad = AppDomain.CurrentDomain;
        Console.WriteLine();
        Console.WriteLine("FriendlyName: {0}", ad.FriendlyName);
        Console.WriteLine("Id: {0}", ad.Id);
        Console.WriteLine("IsDefaultAppDomain: {0}", ad.IsDefaultAppDomain());

Remarks

Every managed process has a default application domain. Execution begins in the default domain.
