==AppDomain.CreateDomain==

<source lang="csharp">

using System;
class MainClass
{
public static void Main()
{
AppDomainSetup setupInfo = new AppDomainSetup();
setupInfo.ApplicationBase = @"C:\MyRootDirectory";
setupInfo.ConfigurationFile = "MyApp.config";
setupInfo.PrivateBinPath = "bin;plugins;external";
AppDomain newDomain = AppDomain.CreateDomain("My New AppDomain", null, setupInfo);
}
}
</source>

==Configure the AppDomainSetup==

<source lang="csharp">
using System;
class Test
{
public static void Main()
{
AppDomainSetup setupInfo = new AppDomainSetup();
setupInfo.ApplicationBase = @"C:\MyRootDirectory";
setupInfo.ConfigurationFile = "MyApp.config";
setupInfo.PrivateBinPath = "bin;plugins;external";
AppDomain newDomain =
AppDomain.CreateDomain("My New AppDomain", null, setupInfo);
}
}

==creates three instances of the same type. A local and two remote proxies to object instances are constructed:==

<source lang="csharp">
using System;
using System.Reflection;
using System.Runtime.Remoting;

class MyClass {
public void MethodA(DateTime dt) {
Console.WriteLine("MethodA invoked at " + dt.ToLongTimeString());
}
}
class Starter {
static void Main() {
CreateLocal();
CreateRemote1();
CreateRemote2();
}
static void CreateLocal() {
object obj = Activator.CreateInstance(typeof(MyClass));
((MyClass)obj).MethodA(DateTime.Now);
}
static void CreateRemote1() {
ObjectHandle hObj = Activator.CreateInstance("library","MyClass");
object obj = hObj.Unwrap();
MethodInfo method = obj.GetType().GetMethod("MethodA");
method.Invoke(obj, new object[1] { DateTime.Now });
}
static void CreateRemote2() {
AppDomain domain = AppDomain.CurrentDomain;
object obj = domain.CreateInstanceFromAndUnwrap("library.dll","MyClass");
MethodInfo method = obj.GetType().GetMethod("MethodA");
method.Invoke(obj, new object[1] { DateTime.Now });
}
}
</source>

==FriendlyName==

<source lang="csharp">
using System;
using System.Collections.Generic;
using System.Text;
class Program {
static void Main(string[] args) {
AppDomain currentDomain = AppDomain.CurrentDomain;
Console.WriteLine(currentDomain.FriendlyName);
AppDomain secondDomain = AppDomain.CreateDomain("New AppDomain");
secondDomain.CreateInstance("AssemblyA", "AppDomains.Demo", true,System.Reflection.BindingFlags.CreateInstance, null, new object[] { 7, 3 }, null, null, null);
}
}
</source>

==OnUnhandledException method is added to the AppDomain.UnhandledException event==

<source lang="csharp">
using System;
public class Starter {
public static void Main() {
AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(OnUnhandledException);
int vara = 5, varb = 0;
vara /= varb;
}
public static void OnUnhandledException(
object sender, UnhandledExceptionEventArgs e) {
string application_name = sender.ToString();
Exception except = (Exception)e.ExceptionObject;
string errormessage = "Application " + application_name +
" [ Exception " + except.Message + " ]";
Console.WriteLine(errormessage);
}
}
</source>

==SetData, GetData==

<source lang="csharp">
using System;
using System.Reflection;
using System.Collections;
class ListModifier{
public ListModifier()
{
ArrayList list = (ArrayList)AppDomain.CurrentDomain.GetData("Pets");
list.Add("turtle");
}
}
class MainClass{
public static void Main(){
AppDomain domain = AppDomain.CreateDomain("Test");
ArrayList list = new ArrayList();
list.Add("dog");
list.Add("cat");
list.Add("fish");
domain.SetData("Pets", list);
domain.CreateInstance("MainClass","Apress.VisualCSharpRecipes.Chapter03.ListModifier");
foreach (string s in (ArrayList)domain.GetData("Pets")) {
Console.WriteLine(s);
}
}
}
</source>

==SetPrincipalPolicy==

<source lang="csharp">
using System;
using System.Security;
using System.Security.Principal;
using System.Security.Permissions;
class Program {
static void Main(string[] args) {
AppDomain.CurrentDomain.SetPrincipalPolicy(PrincipalPolicy.WindowsPrincipal);
try {
ShowMessage();
} catch (SecurityException exception) {
Console.WriteLine(exception.Message);
}
}
[PrincipalPermissionAttribute(SecurityAction.Demand,Role = "BUILTIN\\Users")]
static void ShowMessage() {
Console.WriteLine("The current principal is logged in locally ");
Console.WriteLine("(they are a member of the local Users group)");
}
}
