標籤:我們之前介紹過,在某一個函數中,不應該有兩個名字相同的變數。可是,我們拿下面這段程式碼(程式11.1.3)去測試一下,發現居然在同一個函數中可以有兩個名字相同的變數。這又是怎麼回事呢?編譯器又是如何辨別這兩個名字相同的變數的呢?#include "iostream.h"int main(){ int a=3,b=4; { int a=5,b=6; {
標籤:擴充方法就是一種特殊的靜態方法,不用建立衍生類別和重新編譯原始類型。例:判斷今天是周末還是工作日DateTime date = new DateTime(2015, 4, 2);switch (dateTime.DayOfWeek){ case DayOfWeek.Saturday: case DayOfWeek.Sunday: return true; default: return
