Using Role-Based Security in Managed COM+ Applications

When using role-based security (RBS) with COM+ managed applications, you can pass only COM types to the COM+ server. The following example demonstrates using RBS with COM+ managed applications.

Code Example: Using RBS in Managed COM+ Applications

using System;
using System.EnterpriseServices;

[assembly: ApplicationName("SimpleRoles")]
[assembly: ApplicationActivation(ActivationOption.Server)]
[assembly: ApplicationAccessControl
(true, AccessChecksLevel=
AccessChecksLevelOption.ApplicationComponent)]
[assembly: SecurityRole("CompUsers", SetEveryoneAccess=true)]
[assembly: SecurityRole("Marshaler", SetEveryoneAccess=true)]

namespace Client.Chapter_10___Interop_Services
{
          public interface IMyArrayTests
          {
                 int Test1Add(int Prop1, int Prop2);
                 int Test2Add(int[] MyArray);
                 void Test3Add(ref int[] MyArray);
          }

          [ComponentAccessControl]
          [SecureMethod]
          public class MyObj: ServicedComponent, IMyArrayTests
          {
                     public MyObj(){ }

                  [SecurityRole("CompUsers", true)]
                  public int Test1Add(int Prop1, int Prop2)
                  {
                          return (Prop1 + Prop2);
                  }

                  [SecurityRole("CompUsers", true)]
                  public int Test2Add(int[] MyArray)
                  {
                         return ((int)MyArray.GetValue(0) +
                           (int)MyArray.GetValue(1));
                  }

                  [SecurityRole("CompUsers", true)]
                  public void Test3Add(ref int[] MyArray)
                  {
                          MyArray.SetValue(((int)MyArray.GetValue(0) +
                             (int)MyArray.GetValue(1)), 2);
                          return;
                  }
          }
}
