从应用程序域中检索安装信息

  • 项目

注意

本文特定于 .NET Framework。 它不适用于 .NET 的较新版本实现，包括 .NET 6 及更高版本。

应用程序域的每个实例由属性和 AppDomainSetup 信息组成。 可使用 System.AppDomain 类从应用程序域中检索安装信息。 此类提供多个成员，可用于检索应用程序域的相关配置信息。

还可以查询应用程序域的 AppDomainSetup 对象，获取创建域时传递到该域的安装信息。

下面的示例创建新的应用程序域，然后将几个成员值打印到控制台。

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

下面的示例设置并检索某一应用程序域的安装信息。 使用 AppDomain.SetupInformation.ApplicationBase 可获取配置信息。

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
