從應用程式定義域擷取安裝資訊

  • 發行項

注意

本文專屬於 .NET Framework。 其不適用於較新的 .NET 實作，包括 .NET 6 和更新版本。

每個應用程式定義域的執行個體都包含這兩個屬性及 AppDomainSetup 資訊。 您可以從使用 System.AppDomain 類別的應用程式定義域擷取安裝資訊。 這個類別提供數個成員，它們會擷取應用程式定義域的組態資訊。

您也可以查詢應用程式定義域的 AppDomainSetup 物件，取得在建立時即已傳遞至定義域的安裝資訊。

下例會建立新的應用程式定義域，然後將數個成員值列印到主控台。

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();
}

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);
    }
}

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

然後，下列範例集會擷取應用程式定義域的安裝資訊。 AppDomain.SetupInformation.ApplicationBase 取得設定資訊。

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();
}

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);
    }
}

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
