从应用程序域中检索安装程序信息

更新：2007 年 11 月

应用程序域的每个实例同时包含属性和 AppDomainSetup 信息。您可以使用 System.AppDomain 类从应用程序域中检索安装信息。此类提供了几个检索有关应用程序域的配置信息的成员。

您也可以查询应用程序域的 AppDomainSetup 对象，获取创建该对象时传递至域的安装信息。

下面的示例创建新的应用程序域，然后将几个成员值输出至控制台。

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 'Main
End Class 'AppDomain3

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);
   }
}

下面的示例设置并检索应用程序域的安装信息。请注意，AppDomain.SetupInformation.ApplicationBase 获取配置信息。

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 'Main
End Class 'AppDomain5

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);
   }
}
