ASP.NET MVC中异常控制流的替代方法

Question

I have read that exception control flow is a bad idea.

if(products.length == 0)
   throw new CustomException("Product is required");

I am using ajax at the moment for my requests and if a 500 error happens I catch them in an Exception filter that returns the exception in a strongly typed object that is sent to the client in JSON to be shown in a popup. In an ASP.NET MVC applicacation what is the better alternative and an example?

如果这是出于模型验证的目的，则最好使用数据注释等标准技术，或者，如果您像我一样，发现它们在复杂的验证场景中难以使用，则还可以签出FluentValidation.NET 。
