linq to sql 自动生成，覆盖验证属性的解决方案：

　　首先我们可以简单的想，直接在Linq to SQL 生成的cs文件中引用System.ComponentModel.DataAnnotations，然后在对应的Property中加我们所需要的Annotatio，从理想的状态来讲，我们说这个方案是可行的，但是前提条件是你所设计的Table、Stored Procedure或者Function 结构不会再更改，因为当我们Linq to SQL里的对象在Database的结构发生变化时，我们需要删除Linq to SQL文件中的对象，然后从Database重新的拖入，以生成更新后的强类型文件，那么我们之前加入的Annotation也会被删除掉，后果就是我们需要重新加注Data Annotation，这样会增加我们很大的工作量， 那么我们如何来解决这样的问题呢？

　　在Linq to SQL中，如果你的Database的表的名称是T_PRODUCT，那么当你把表插入到Linq to SQL的文件中生，他会帮我们生成对应名称为Staffs的Class。

我们的解决方案是定义一个新的Class（我们这里叫StaffsAnnotation
），然后在里面加入哪些需要加注Annotation的Properties（Property的名字需要和Staffs表中的字段相同）

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ComponentModel.DataAnnotations;
using System.ComponentModel;

namespace SkySolar.Models
{
    public class StaffsAnnotation
    {
        [Required(ErrorMessage="LoginName is Required.")]
        [StringLength(50,ErrorMessage="Max Length of Loginname can not greate than 50 characters.")]
        public string Loginname { get; set; }

        [Required(ErrorMessage="PassWord is Required.")]
        [StringLength(50,ErrorMessage="Max Length of Product Name can not greater than 20 characters.")]
        public string PassWord { get; set; }

        [DisplayName("Name:")]
        [Required(ErrorMessage="Realname is Required.")]
        public string Realname { get; set; }

    }
}

之后：

using System.ComponentModel.DataAnnotations;
namespace SkySolar.Models
{
    [MetadataType(typeof(StaffsAnnotation))]
    public partial class Staffs
    {

    }
}

到此实现对Linq to SQL生成的强类型Class加Validation。

<script src="../js/jquery.js" type="text/javascript"></script>
<script src="../js/jquery.validate.js" type="text/javascript"></script>
<script src="./js/jquery.metadata.js" type="text/javascript"></script>
$().ready(function() { $("#signupForm").validate(); });
<form id="signupForm" method="get" action="">
<p>
    <label for="firstname">
        Firstname</label>
    <input id="firstname" name="firstname" class="required" />
</p>
<p>
    <label for="email">
        E-Mail</label>
    <input id="email" name="email" class="required email" />
</p>
<p>
    <label for="password">
        Password</label>
    <input id="password" name="password" type="password" class="{required:true,minlength:5}" />
</p>
<p>
    <label for="confirm_password">
        确认密码</label>
    <input id="confirm_password" name="confirm_password" type="password" class="{required:true,minlength:5,equalTo:'#password'}" />
</p>
<p>
    <input class="submit" type="submit" value="Submit" />
</p>
</form>
meta: "validate"
<input id="password1" name="password" type="password" class="{validate:{required:true,minlength:5}}" />
$.metadata.setType("attr", "validate");这样可以使用validate="{required:true}"的方式，或者class="required"，但class="{required:true,minlength:5}"将不起作用
2.将校验规则写到代码中 $().ready(function() { $("#signupForm").validate({ rules: { firstname:
"required", email: { required: true, email: true }, password: { required: true,
minlength: 5 }, confirm_password: { required: true, minlength: 5, equalTo: "#password"
} }, messages: { firstname: "请输入姓名", email: { required: "请输入Email地址", email: "请输入正确的email地址"
}, password: { required: "请输入密码", minlength: jQuery.format("密码不能小于{0}个字符") }, confirm_password:
{ required: "请输入确认密码", minlength: "确认密码不能小于5个字符", equalTo: "两次输入密码不一致不一致" } } });
});//messages处，如果某个控件没有message，将调用默认的信息
<form id="Form1" method="get" action="">
<p>
    <label for="firstname">
        Firstname</label>
    <input id="Text1" name="firstname" />

        E-Mail</label>
