AppDomain
.Netの実行環境階層構造
Process – AppDomain —- RunSpace
かな?
- Process メモリ空間を共有する。
- AppDomain : アセンブリ空間共有
- RunSpace : コンテキスト共有
一つのAppDomainに最大1つのアプリケーションクラスを持てる。
コード例/msdn
using System; using System.Reflection; using System.Threading; class Module1 { public static void Main() { // Get and display the friendly name of the default AppDomain. string callingDomainName = Thread.GetDomain().FriendlyName; Console.WriteLine(callingDomainName); // Get and display the full name of the EXE assembly. string exeAssembly = Assembly.GetEntryAssembly().FullName; Console.WriteLine(exeAssembly); // Construct and initialize settings for a second AppDomain.
