// ShouldSerialize<PropertyName> 函数是 VS 属性浏览器用来检查具体某个属性是否必须序列化的函数。为所有 ValueType 属性(类型为 Int32、BOOL 等的属性，不能将它们设置为空)添加这些函数。这些函数使用 Is<PropertyName>Null 函数。这些函数还在属性的 TypeConverter 实现中用来检查属性的 NULL 值，以便在 Visual Studio 中进行拖放操作时可以在属性浏览器中显示空值。
// 函数 Is<PropertyName>Null() 用于检查属性是否为 NULL。
// 为可为空值的读/写属性添加 Reset<PropertyName> 函数。这些函数由 VS 设计器用来在属性浏览器中将属性设置为 NULL。
