C# MVC过滤器属性-多个选项作为过滤器参数

嗨，我的

C 35;

控制器有一个自定义过滤器属性

 [SessionExpireFilterAttribute(UserType = UserTypes.Admin)]

我的过滤器是这样启动的：

[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, Inherited = true, AllowMultiple = true)]
    public class SessionExpireFilterAttribute : ActionFilterAttribute
    {
        public App.Model.UserTypes UserType { get; set; }

        public override void OnActionExecuting(ActionExecutingContext filterContext)
        {
            HttpContext ctx = HttpContext.Current;

[SessionExpireFilterAttribute(UserType = UserTypes.Admin || UserTypes.Accounting || UserTypes.Standard)]

public App.Model.UserTypes[] UserTypes { get; set; }

public SessionExpireFilterAttribute(params App.Model.UserType[] values) {
    UserTypes = values;
}

[SessionExpireFilterAttribute(UserTypes.Admin, UserTypes.Accounting, UserTypes.Standard)]

我想要的是能够发送多个

用户类型

，因此此控制器的权限不仅仅与一个相关

例如，要设置如下内容：

[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, Inherited = true, AllowMultiple = true)]
    public class SessionExpireFilterAttribute : ActionFilterAttribute
    {
        public App.Model.UserTypes UserType { get; set; }

        public override void OnActionExecuting(ActionExecutingContext filterContext)
        {
            HttpContext ctx = HttpContext.Current;

[SessionExpireFilterAttribute(UserType = UserTypes.Admin || UserTypes.Accounting || UserTypes.Standard)]

public App.Model.UserTypes[] UserTypes { get; set; }

public SessionExpireFilterAttribute(params App.Model.UserType[] values) {
    UserTypes = values;
}

[SessionExpireFilterAttribute(UserTypes.Admin, UserTypes.Accounting, UserTypes.Standard)]

这样，如果用户类型是

Admin

或

Accounting

或

Standard

，我可以在过滤器中执行逻辑，让流程继续

有线索吗

您可以使用数组进行此操作，如下所示：

[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, Inherited = true, AllowMultiple = true)]
    public class SessionExpireFilterAttribute : ActionFilterAttribute
    {
        public App.Model.UserTypes UserType { get; set; }

        public override void OnActionExecuting(ActionExecutingContext filterContext)
        {
            HttpContext ctx = HttpContext.Current;

[SessionExpireFilterAttribute(UserType = UserTypes.Admin || UserTypes.Accounting || UserTypes.Standard)]

public App.Model.UserTypes[] UserTypes { get; set; }

public SessionExpireFilterAttribute(params App.Model.UserType[] values) {
    UserTypes = values;
}

[SessionExpireFilterAttribute(UserTypes.Admin, UserTypes.Accounting, UserTypes.Standard)]

然后你可以这样使用它：

[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, Inherited = true, AllowMultiple = true)]
    public class SessionExpireFilterAttribute : ActionFilterAttribute
    {
        public App.Model.UserTypes UserType { get; set; }

        public override void OnActionExecuting(ActionExecutingContext filterContext)
        {
            HttpContext ctx = HttpContext.Current;

[SessionExpireFilterAttribute(UserType = UserTypes.Admin || UserTypes.Accounting || UserTypes.Standard)]

public App.Model.UserTypes[] UserTypes { get; set; }

public SessionExpireFilterAttribute(params App.Model.UserType[] values) {
    UserTypes = values;
}

[SessionExpireFilterAttribute(UserTypes.Admin, UserTypes.Accounting, UserTypes.Standard)]

注意：您不必使用

params

，您也可以这样做

[SessionExpireFilterAttribute(new [] {UserTypes.Admin, UserTypes.Accounting, UserTypes.Standard})]
