The following example demonstrates how to use the SetAppDomainPolicymethod to set the security policy level of an application domain.
using System; using System.Threading; using System.Security; using System.Security.Policy; using System.Security.Permissions; namespace AppDomainSnippets { class ADSetAppDomainPolicy { static void Main(string[] args) { // Create a new application domain. AppDomain domain = System.AppDomain.CreateDomain("MyDomain"); // Create a new AppDomain PolicyLevel. PolicyLevel polLevel = PolicyLevel.CreateAppDomainLevel(); // Create a new, empty permission set. PermissionSet permSet = new PermissionSet(PermissionState.None); // Add permission to execute code to the permission set. permSet.AddPermission (new SecurityPermission(SecurityPermissionFlag.Execution)); // Give the policy level's root code group a new policy statement based // on the new permission set. polLevel.RootCodeGroup.PolicyStatement = new PolicyStatement(permSet); // Give the new policy level to the application domain. domain.SetAppDomainPolicy(polLevel); // Try to execute the assembly. try { // This will throw a PolicyException if the executable tries to // access any resources like file I/O or tries to create a window. domain.ExecuteAssembly("Assemblies\\MyWindowsExe.exe"); } catch(PolicyException e) { Console.WriteLine("PolicyException: {0}", e.Message); } AppDomain.Unload(domain); } } }
