如何在ASP.NET MVC4中验证除当前上下文之外的模型 [英] How to validate model other than in current context in ASP.NET MVC4

问题描述

我有一个由三个组成的聚合模型：

I've an aggregate model composed of three:

public class Shipments
   {
       public Shipment Shipment { get; set; }
       public AirInvoice AirInvoice { get; set; }
       public SeaInvoice SeaInvoice { get; set; }
   }

[HttpPost]
public ActionResult Create(Shipments shipmentModel)
  {
     //ToDo - Validate shipmentModel.Shipment
  }

我正在尝试使用DataAnnotations ValidationContext验证它，但无法：

I'm trying to validate it using DataAnnotations ValidationContext but not being able to:

var context = new ValidationContext(shipmentModel.Shipment); //Error Here. validation context has 3 parameters but invoked with one parameter, though I'm able to see there's a constructor with one parameter also in ValidationContext.cs and recently I was able to do the same but now it's not working... don't know why.

           var results = new List<ValidationResult>();
           bool LoginModelIsValid = Validator.TryValidateObject(loginModel, context,results,true);
