标签：container rri sharp write 委托方 code 实体类 order index
委托的实现，就是编译器自行定义了一个类：有三个重要参数1.制定操作对象，2.指定委托方法3.委托链
看如下一个列子：

class DelegatePratice { public static void Sort<T>(IList<T> sortArray, Func<T, T, bool> Comparison) { bool swapped = true; do { swapped= false; for (int i = 0; i < sortArray.Count - 1; i++) { if (Comparison(sortArray[i], sortArray[i + 1])) { T temp = sortArray[i]; sortArray[i] = sortArray[i + 1]; sortArray[i + 1] = temp; swapped = true; } } } while (swapped); } }<br><br>定义实体类： |
