MVC Validation Lower/Higher than other value

Question

How is the best way to validate a model in MVC.Net where I want to accept a minimum/maximum.

Not individual min/max values for a field. But separate fields for a use

Answer 1

There is a NuGet package called Foolproof which provides these annotations for you. That said - writing a custom attribute is both pretty easy and good practice.

Using Foolproof would look like:

public class FinanceModel{
   public int MinimumCost {get;set;}

   [GreaterThan("MinimumCost")]
   public int MaximumCost {get;set;}
}
