Recuperar información de instalación de un dominio de aplicación

Todas las instancias de un dominio de aplicación están formadas por propiedades y por información de AppDomainSetup. La información de instalación se puede recuperar de un dominio de aplicación mediante la clase System.AppDomain. Esta clase proporciona varios miembros que recuperan la información de configuración de un dominio de aplicación.

También se puede consultar el objeto AppDomainSetup del dominio de aplicación para obtener la información de instalación que se paso al dominio cuando se creó.

En el ejemplo siguiente se crea un nuevo dominio de aplicación y, a continuación, se imprimen varios valores de miembros en la consola.

Imports System
Imports System.Reflection

Class AppDomain3
    Public Shared Sub Main()
        ' Create the new application domain.
        Dim domain As AppDomain = AppDomain.CreateDomain("MyDomain", Nothing)

        ' Output to the console.
        Console.WriteLine("Host domain: " + AppDomain.CurrentDomain.FriendlyName)
        Console.WriteLine("New domain: " + domain.FriendlyName)
        Console.WriteLine("Application base is: " + domain.BaseDirectory)
        Console.WriteLine("Relative search path is: " + domain.RelativeSearchPath)
        Console.WriteLine("Shadow copy files is set to: " + domain.ShadowCopyFiles)
        AppDomain.Unload(domain)
    End Sub
End Class

using System;
using System.Reflection;

class AppDomain3
{
    public static void Main()
    {
        // Create the new application domain.
        AppDomain domain = AppDomain.CreateDomain("MyDomain", null);

        // Output to the console.
        Console.WriteLine("Host domain: " + AppDomain.CurrentDomain.FriendlyName);
        Console.WriteLine("New domain: " + domain.FriendlyName);
        Console.WriteLine("Application base is: " + domain.BaseDirectory);
        Console.WriteLine("Relative search path is: " + domain.RelativeSearchPath);
        Console.WriteLine("Shadow copy files is set to: " + domain.ShadowCopyFiles);
        AppDomain.Unload(domain);
    }
}

using namespace System;
using namespace System::Reflection;

ref class AppDomain3
{
public:
    static void Main()
    {
        // Create the new application domain.
        AppDomain^ domain = AppDomain::CreateDomain("MyDomain", nullptr);

        // Output to the console.
        Console::WriteLine("Host domain: " + AppDomain::CurrentDomain->FriendlyName);
        Console::WriteLine("New domain: " + domain->FriendlyName);
        Console::WriteLine("Application base is: " + domain->BaseDirectory);
        Console::WriteLine("Relative search path is: " + domain->RelativeSearchPath);
        Console::WriteLine("Shadow copy files is set to: " + domain->ShadowCopyFiles);
        AppDomain::Unload(domain);
    }
};

int main()
{
    AppDomain3::Main();
}

En el siguiente ejemplo se establece, y después se recupera, información de instalación de un dominio de aplicación. Tenga en cuenta que AppDomain.SetupInformation.ApplicationBase obtiene la información de configuración.

Imports System
Imports System.Reflection

Class AppDomain5
    Public Shared Sub Main()
        ' Application domain setup information.
        Dim domaininfo As New AppDomainSetup()
        domaininfo.ApplicationBase = "f:\work\development\latest"
        domaininfo.ConfigurationFile = "f:\work\development\latest\appdomain5.exe.config"

        ' Creates the application domain.
        Dim domain As AppDomain = AppDomain.CreateDomain("MyDomain", Nothing, domaininfo)

        ' Write the application domain information to the console.
        Console.WriteLine("Host domain: " + AppDomain.CurrentDomain.FriendlyName)
        Console.WriteLine("Child domain: " + domain.FriendlyName)
        Console.WriteLine()
        Console.WriteLine("Application base is: " + domain.SetupInformation.ApplicationBase)
        Console.WriteLine("Configuration file is: " + domain.SetupInformation.ConfigurationFile)

        ' Unloads the application domain.
        AppDomain.Unload(domain)
    End Sub
End Class

using System;
using System.Reflection;

class AppDomain5
{
    public static void Main()
    {
        // Application domain setup information.
        AppDomainSetup domaininfo = new AppDomainSetup();
        domaininfo.ApplicationBase = "f:\\work\\development\\latest";
        domaininfo.ConfigurationFile = "f:\\work\\development\\latest\\appdomain5.exe.config";

        // Creates the application domain.
        AppDomain domain = AppDomain.CreateDomain("MyDomain", null, domaininfo);

        // Write the application domain information to the console.
        Console.WriteLine("Host domain: " + AppDomain.CurrentDomain.FriendlyName);
        Console.WriteLine("Child domain: " + domain.FriendlyName);
        Console.WriteLine();
        Console.WriteLine("Application base is: " + domain.SetupInformation.ApplicationBase);
        Console.WriteLine("Configuration file is: " + domain.SetupInformation.ConfigurationFile);

        // Unloads the application domain.
        AppDomain.Unload(domain);
    }
}

using namespace System;
using namespace System::Reflection;

ref class AppDomain5
{
public:
    static void Main()
    {
        // Application domain setup information.
        AppDomainSetup^ domaininfo = gcnew AppDomainSetup();
        domaininfo->ApplicationBase = "f:\\work\\development\\latest";
        domaininfo->ConfigurationFile = "f:\\work\\development\\latest\\appdomain5.exe.config";

        // Creates the application domain.
        AppDomain^ domain = AppDomain::CreateDomain("MyDomain", nullptr, domaininfo);

        // Write the application domain information to the console.
        Console::WriteLine("Host domain: " + AppDomain::CurrentDomain->FriendlyName);
        Console::WriteLine("Child domain: " + domain->FriendlyName);
        Console::WriteLine();
        Console::WriteLine("Application base is: " + domain->SetupInformation->ApplicationBase);
        Console::WriteLine("Configuration file is: " + domain->SetupInformation->ConfigurationFile);

        // Unloads the application domain.
        AppDomain::Unload(domain);
    }
};

int main()
{
    AppDomain5::Main();
}
