对象(Object)类型可以被分配任何其他类型(值类型、引用类型、预定义类型或用户自定义类型)的值。但是,在分配值之前,需要先进行类型转换。 动态类型dynamic C# string 字符串的前面可以加 @(称作"逐字字符串")将转义字符(\)当作普通字符对待 IntPtr 表示 或指针的特定类型 索引器 索引器(Indexer) 允许一个对象可以...
if employee1 = employee2 then//...而这段代码将完全符合我们的意思——真正的相等。 通过引用比较对象的 Equals 是纯粹多余的，我们已经有了 Object.ReferenceEquals，谢谢。有人可能会争辩说没有人需要它，因为在现实生活中我们很少比较对象，因此手动覆盖 Equals 和 GetHashCode 没什么大不了的。 但我认为因果...

Key type can choose int or string. If key type is int, serialized format is used array. If key type is string, serialized format is used map. If you define [MessagePackObject(keyAsPropertyName: true)], does not require KeyAttribute....
If you use[MessagePackObject(keyAsPropertyName: true)], then members do not require explicitKeyattributes, but string keys will be used. [MessagePackObject]publicclassSample1{ [Key(0)]publicintFoo {get;set; } [Key(1)]publicintBar {get;set; } ...

intFunction(objecta,objectb){ASSERT(a!=null);ASSERT(b!=null);...} 8. 尽量用乘法或其它方法代替除法,特别是浮点运算中的除法,但是要注意精度溢出的问题。整数乘除法在保证不溢出的情况下,先除后乘。 9. 保持单线程逻辑,除了调用异步I/O接口之外,不能使用多线程。 10...
