Validation in ASP.NET Web Pages (Razor) deprecated?

问题

I'm trying to use Validation in razor, but when I try to use the line

Validation.RequireFields("firstName", "lastName", "dateOfBirth");

visual studio tells me:

'System.Web.Helpers.Validation' is obsolete: '"Use System.Web.HttpRequest.Unvalidated instead."'

and

'System.Web.Helpers.Validation' does not contain a definition for 'RequireFields'

but the most up to date reference I can find is http://www.asp.net/web-pages/overview/more-resources/asp-net-web-pages-api-reference#Validation and I don't really see how Unvalidated is supposed to do what I want.

How do I do validation?

Thanks!

Here's my web.config in case it's relevant:

<?xml version="1.0"?>

<configuration>
  <configSections>
    <sectionGroup name="system.web.webPages.razor" type="System.Web.WebPages.Razor.Configuration.RazorWebSectionGroup, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">

回答1:

Do validation on your model with attributes:

public class MyModel
{
  [Required][StringLength(100)]
  public string FirstName {get;set;}
}

See this excellent blog post which explains it quite nicely. Also if the framework attributes don't fulfill your requirements, this library has a lot of extra attributes.
