如何在Asp.net Core的自定义属性中使用<t>

Question

如何像这样在asp.net核心的属性中使用<MyModel>

[CAttr<MyModel>()]
public ActionResult Index(string data)
{
    ....
}

我的属性是

public class CAttr : ActionFilterAttribute
{
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        var temp = MyOperation.Get<MyModel>();
        ....
    }
}
