AppDomain.IsDefaultAppDomain Method

Definition

Namespace:

System

Assemblies:

netstandard.dll, System.Runtime.dll

Source:

AppDomain.cs

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

C#

public bool IsDefaultAppDomain();

Returns

Boolean

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.

C#

using System;
using System.Reflection;

public class AppDomainIdSnippet
{
    // The following attribute indicates to the loader that assemblies
    // in the global assembly cache should be shared across multiple
    // application domains.
    [LoaderOptimizationAttribute( LoaderOptimization.MultiDomainHost)]
    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.
    //
    public static void ShowDomainInfo()
    {
        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.
