Application domains
Question: Write a C# program AppLauncher that can launch
and run other applications. Each of these applications should run in its own
application domain (not in a separate process!).
Answer: see 3.7.1 Application Domains
AppLauncher.cs
using System;
using System.Threading;
class AppLauncher {
class AppThread {
AppDomain domain;
string uri;
public AppThread (string appURI) {
uri = appURI;
domain = AppDomain.CreateDomain(uri);
}
public void Execute () {
try {
domain.ExecuteAssembly(uri);
} catch (Exception e) {
Console.WriteLine("Exception while executing " + domain.FriendlyName);
Console.WriteLine(e);
}
}
}
static void Main () {
for (;;) {
Console.WriteLine();
Console.Write(">");
string appURI = Console.ReadLine();
try {
if (appURI == "exit") break;
else if (if (appURI == null || appURI.Length == 0)
throw new Exception("No application specified");
AppThread at = new AppThread(appURI);
Thread t = new Thread(new ThreadStart(at.Execute));
t.Start();
} catch (Exception e) {
Console.WriteLine(e);
}
}
}
}
