PropertyComparisonValidator

[PropertyComparisonValidator("ComparePropB", ComparisonOperator.Equal)]

publicstringComparePropA { get; set; }

publicstringComparePropB { get; set; }

这段代码的意思是，验证属性ComparePropA是否等于ComparePropB。

这个验证器的构造函数有2个，接收3类参数：

1）字符串propertyToCompare，表示要比较的属性名

2）枚举ComparisonOperator，比较类型枚举，具体有：Equal（等于）、NotEqual（不等于）、GreaterThan（大于）、GreaterThanEqual（大于等于）、LessThan（小于）、LessThanEqual（小于等于）

3）命名参数
