The async/await of. NET 4.5 is really a magic thing. It's so clever that I can't help but wonder about its implementation, but it's hard to get a glimpse of its path. Unexpectedly, I read this article Asynchronous Programming in C # using Iterators, which is like a crash. Meiyu did not dare to exclusive, so I wrote this article to share some of my thoughts with them, and I will give them some valuable insig

One of the problems with object-oriented programming is the so-called "code expansion" feature. To illustrate all possible data types of method parameters, code expansion occurs when you need to overload a method or reload a set of methods. One solution to code expansion is to make a value present multiple data types, and only provide a definition of this value. This method is called model programming. Mode

foreword: At present in the study Kr's book "C Programming Linguistics", because has not contacted the C language for several years, therefore this re-study, absorbed the online predecessor's experience: develops the good writing code style and through the blog study summarizes and ponders. today read the book on the Fahrenheit temperature and Celsius temperature

AVLTree (Adelson-Velskii-Landis Tree)Is a binary search tree with additional conditions. The balance condition is established to ensure that the depth of the entire tree is O (nlogn ). The balance condition is that the height difference between left and right subtree of any node cannot exceed 1. In the following code,Programming allows you to establish, search, insert, delete, and traverse AVL trees.. C ++

The first two days saw the fourth chapter in advanced Programming in C #: Inheritance and Chapter Sixth: arrays. Three major features of OOP: encapsulation, inheritance, polymorphism, personal feeling inheritance is the basis for the realization of polymorphism, including the design patterns of future contact, are derived from inheritance characteristics.There are two inheritance attributes, which implement

　　Reading directoryI. Preface Ii. What is the difference between interfaces and abstract classes? 　　I. PrefaceIn object-oriented programming, abstraction is an agreement that the successor or implementer must follow. For example, if a class inherits or implements an interface, the class must implement all the members of the interface, an interface is an abstraction of A Class. A Class must follow the protocol of all its members. 　　Ii. What is the diff
