    Hi

    I see the following code:

    public class AgenteAdministracion : IDisposable
       {
           private readonly IServiceConsumer<IServicioAdministracion> proxy;
     
           public AgenteAdministracion()
           {
               proxy = ServiceConsumerFactory.Create<IServicioAdministracion>(() => new ServicioAdministracionClient());
           }  
     
           public async Task<T> InvocarFuncionAsync<T>(Expression<Func<IServicioAdministracionTask<T>>> func)
           {
               var result = await proxy.ConsumeAsync<T>(func);
               return AgenteUtil.ObtenerResultado<T>(result);
           }
     
           public async Task InvocarAccionAsync(Expression<Func<IServicioAdministracionTask>> func)
           {            
               var result = await proxy.ConsumeAsync(func);
               AgenteUtil.FinalizarResultado(result);
           }
     
           public void Dispose()
           {
               if (proxy != null)
                   proxy.Dispose();
           }
       }

    What is the function of IDisposable in this code.

    hi

    IDisposable is an interface that contains a single method, <g class="gr_ gr_13 gr-alert gr_gramm gr_inline_cards gr_run_anim Grammar only-ins replaceWithoutSep" id="13" data-gr-id="13">Dispose</g>(), for releasing unmanaged resources, like files, streams, database connections and so on. This method is implemented explicitly in the code when we need to clean up a disposable object and to release unmanaged resources that this disposable object holds.

    The Dispose method is implemented explicitly by the programmer and there is the chance that the programmer fails or forgets to dispose of the unmanaged resources, so the Finalize method should be called for a safer side to prevent a memory leak. If the Dispose method is not called for any reason then the destructor would be called by the garbage collector, but when the Finalize method would be called by the garbage collector is not determined. The garbage collector can call it anytime there is a requirement of more memory or when the program exits or anytime on some other conditions.
