Read and write operations on the file should be the most important file operations, System.IO namespace for us to provide a number of file read and write operation classes, here I want to introduce the most common is the most basic StreamReader class and StreamWriter class. From the names of these two classes, it is not difficult to find that they are both stream-based read and write operations classes.We c

C ++ abstract class An Object-Oriented story The most important concept of object-oriented programming language is undoubtedly class, and everything is object. (but if I write code in front of a computer every day to study object-oriented languages, it is very diffic

The MongoDbCsharpHelper class (CRUD class) is encapsulated based on the official MongoDb C # driver ), MongoDb is used as a log persistence object in recent work. MongoDb needs to be added, deleted, modified, and queried. However, because MongoDb is of a newer version, it is of version 2.4 or later, some of the existing MongoDb Helper classes on the Internet are

The idea of oo programming has become more and more common, However, some basic things are still vague, For example, the call sequence of the base class and subclass. Here I use c # as an example to show you how: (The capability is limited. If you have any flaws, please kindly advise ^_^) For the following codePublic class baseClass{Public string a = "baseClass "
