/** 使用说明
* 继承 ValidationAttribute 抽象类，重写 IsValid() 方法，以实现服务端验证
* 实现 IClientValidatable 接口的 GetClientValidationRules() 方法，以实现客户端验证
*
* 1. [IntRangeExpression(18, 30)] 数字在18与30之间,可以不填写，但填写就进入验证
* 2. [MaxWordsExpression(50)] 字符数在不能大50，可以不填写，但填写就进入验证
* 3. [NotNullExpression] 验证是否为空且 调用
* 4. [DateExpression] 是否是日期格式：2012-10-1
* 5. [IsCharExpression] 只能是数字，字母，下划线，中划线组成，可以不填写
* 6. [ChinaCharExpression] 只能输入汉字，可以不填写
* 7. [NotEqualExpression("abcd")] 不能等于指定的值，可以不填写：如不能等于abcd
* 8. [ContainExpression("abc")] 验证是否包含指定字符串，可以不填写：如必须包含abc
* 9. [NotContainExpression("abc")] 验证不能指定字符串,可以不填写,如不能含有abc
*10. [IsIntegerEpression] 验证是否是数字格式 可以不填写,可以为任意整数 1,-5
*11. [IsPositiveIntegerExpression] 验证是否是数字格式，可以不填写,必须是任意正整数 25
*12. [IsNegativeIntegerExpression] 验证是否是数字格式，可以不填写,必须是任意负整数 -25
*13. [IsDecimalExpression] 验证是否是数字格式 可以不填写,可以为任意浮点数 12.12,12,-12.12
*14. [IsPositiveDecimalExpression] 验证是否是数字格式 可以不填写,可以为任意正浮点数 1.4
*15. [IsNegativeDecimalExpression] 验证是否是数字格式 可以不填写,可以为任意负浮点数 -1.2
*16. [EmailExpression] 验证是否是Email
*17. [PhoneExpression] 验证是否是中国电话号码 如：0769-222222-222 正确格式为："XXX-XXXXXXX"、"XXXX- XXXXXXXX"、"XXX-XXXXXXX"、"XXX-XXXXXXXX"、"XXXXXXX"和"XXXXXXXX"。
*18. [SiteExpression] 验证是否是一个完整的网址 如：www.163.com
*19. [IsNumberExpression] 验证是否是数字格式 可以不填写,可以为任意数字
*
*
* 组合使用演示
* [DisplayName("姓名")] 名称
* [NotNullExpression] 不能为空
* [MaxWordsExpression(50)] 最多50个字符，25个汉字
* [IsCharExpression] 只能由数字，字母，中划线，下划线组成（一般用于验证ID）
* [NotEqualExpression("admin")] 不能包含有admin字符串
* public string Id { get; set; }
*
* 数字判断演示
* [IsNumberExpression] 可以不填写，填写判断是否是数字
* [DisplayName("代号")]
* public int? age { get; set; }
* 非空字断使用
* //[Required(ErrorMessageResourceType = typeof(ErrorRs), ErrorMessageResourceName = "IsNumberExpression")]
* 或//[Required(ErrorMessage="必须填写这个字段")] 来覆盖本地化 如public int age; int?为可空字端
