我一直在使用以下代码进行一些测试,以尝试和锻炼ActionFilterAttributes的工作方式:

public class TestAttribute : ActionFilterAttribute
{
    private string _privateValue;
    public string PublicValue { get; set; }

    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        _privateValue = DateTime.Now.ToString();

        base.OnActionExecuting(filterContext);
    }
}

当我在两个并行线程上运行上面的代码时,_privateValue字段会混淆.但是,PublicValue属性不会混淆.

在我看来,ActionFilterAttributes可以跨线程重用,但是根据为公共属性指定的常量创建新实例.我对么？

我在哪里可以找到相关信息？

为什么我无法将SetterProperty通道注入StructureMapMVC ActionFilter？

public class LockProjectFilter : ActionFilterAttribute
    {
        [SetterProperty]
        public ISecurityService SecurityService { get; set; }

        public override void OnActionExecuting(ActionExecutingContext filterContext)
        {
            var loggedinStaffId = SecurityService.GetLoggedInStaffId();
            if (loggedinStaffId == 1)
                throw new ArgumentNullException();
            base.OnActionExecuting(filterContext);
        }
    }


    public static IContainer Initialize()
    {
        ObjectFactory.Initialize(x =>
                         {
                             x.Scan(scan =>
                                            {
                                                scan.TheCallingAssembly();
                                                scan.WithDefaultConventions();
                                                scan.AssemblyContainingType<ISecurityService>();
                                            });
                             x.SetAllProperties(p => p.OfType<ISecurityService>());
                             //x.ForConcreteType<LockProjectFilter>().Configure
                                // .Setter(c => c.SecurityService).IsTheDefault();
                         });
        return ObjectFactory.Container;
    }
