验证在int数据类型的ASP.NET MVC3 [英] Validation on int data type asp .net mvc3

问题描述

我收到值'ABC'是无效的字段名。的错误消息。这是默认的错误消息，我想重写它更简单的方法。
截至目前我已经尝试下面

I am getting The value 'abc' is not valid for fieldName. as error message. which is default error message and i want to override it in easier way.
as of now what i have tried is listed below

• [RegularEx pression（@^ \\ D + $的ErrorMessage =请输入数值）]


• [整数（ErrorMessageResourceType = typeof运算（appName.Resources.abc.Resource）
               ErrorMessageResourceName =error_numeric）]


• [RegularEx pression（（[1-9] [0-9] *））]



• 范围（1，int.max，的ErrorMessage =请输入数值）
  
  但未能改变默认的错误消息。
  
  
  我建议的最简单的方式来做到这一点。
  
  

• [RegularExpression(@"^\d+$",ErrorMessage="enter numeric value")]
• [Integer(ErrorMessageResourceType = typeof(appName.Resources.abc.Resource), ErrorMessageResourceName = "error_numeric")]
• [RegularExpression("([1-9][0-9]*)")]

• Range(1,int.max,ErrorMessage="enter numeric value")
  but failed to change default error message.
  Suggest me the easiest possible way to do this.
  

   using System;
   using System.Collections.Generic;
   using System.Linq;
   using System.Web;
   using System.ComponentModel.DataAnnotations; 
   using System.Web.Mvc;

  namespace blueddPES.ViewModels
     {
     public class ContactViewModel
        {
         [Integer(ErrorMessage="sdfdsf")]
         public int? hp { get; set; }
        }

推荐答案

最简单的方法是使用数据注释扩展。它有一些有用的属性的东西像整数，等等。

Easiest way is to use Data Annotations Extensions. It has some useful attributes for things like Integers, etc.

或者你可以写自己的，像：如何更改数据-VAL-号码消息验证MVC中，而它产生由助手

Or you could write your own, like in: How to change 'data-val-number' message validation in MVC while it generate by helper

修改：意见后添加完整的示例

Edit: Added complete sample after comments.

我创建了一个示例香草MVC 3项目，然后做了以下内容：

I created a sample vanilla MVC 3 project and then did the following:

1. 新增的NuGet包 DataAnnotationsExtensions.MVC3

添加了一个模型类：

public class IntegerSample
{
    [Required(ErrorMessage="Dude, please fill something in!")]
    [Integer(ErrorMessage="Are you stupid? Just fill in numbers only!")]
    public int? TestValue { get; set; }
}

增加了一个家庭控制器：

Added a Home Controller:

public class HomeController : Controller
{
    //
    // GET: /Home/
    public ActionResult Index()
    {
        return View();
    }
}

增加了一个景观：

Added a Home View:

@using (Html.BeginForm()) {
    @Html.ValidationSummary(true)
    <fieldset>
        <legend>IntegerSample</legend>
        <div class="editor-label">
            @Html.LabelFor(model => model.TestValue)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.TestValue)
            @Html.ValidationMessageFor(model => model.TestValue)
        </div>
        <p>
            <input type="submit" value="Save" />
        </p>
    </fieldset>
}

我希望你能使用此示例code一些见解。当我运行这个样本，它的工作原理就像你所想期待。

I hope you get some more insights using this sample code. When I run this sample, it works just as you'd want to expect.
