What's LINQ? Language Integrated Query is also. This is a new feature of the programming language. It can integrate data query statements into the programming language. The main reason is that there are more and more data formats, such as

A bitwise OR combined permission string is encountered at work. I have never been quite clear about it. It finally took half an afternoon to figure out the truth. First, the number of permissions is the N power of 2. For example, k1 = 2; // Add K2 =

C/S chat rooms are divided into server-side and client-side, which must be implemented using multiple threads. The main thread on the server needs to constantly listen to the port. Once a request is sent from the client, the corresponding socket is

The last time we talked about variables, they can be said to be the basis of programming. The main function is to store data, just like cooking. Different dishes should be placed in different types of containers, different data must also be stored

Original question: fzu 2169 http://acm.fzu.edu.cn/problem.php? PID = 1, 2169 This question seems to have two solutions: DFS and spfa. But how can DFS both be re? The spfa also uses an adjacent table to represent the edge. If it is expressed by a

In articles 16th and 17th, we introduced the KVC and KVO features of obj-C. At that time, the example was fun, too abstract, and seemed to be out of touch with reality. Next we will use an actual example to see how KVC and KVO are used. In this

The objective of generics is to use a wide range of applicable and interactive forms to represent algorithms and data structures-parameterization The wildcard can provide powerful type checks during compilation to reduce Explicit conversions

My own notes are messy.   Syntax: If the parameter is of the const type, it only indicates that the parameter cannot be modified in the implementation of this function. It does not mean that the input parameter type must be of the const

Sometimes we need to determine whether a class implements an interface, for example, when using the reflection mechanism (reflection) to find a specific type. To put it simply, you can use the type. isassignablefrom

Everything starts from here. A freshman sent me a C ++ question via QQ: int c = 8, b = 3;c += c-- | ++b; Ask the value of C. After computation, we can see that C is 19, and a C # console project is created at will. It is a tragedy... C # outputs 20

A lightweight ORM framework written by myself is released. This framework is designed based on a three-tier architecture at the beginning. Therefore, from the perspective of naming, it is easy to understand the three-tier architecture. The purpose

Vim's tags module and ctags, vimctags1. Overview In general, jump in code is inseparable from ctags. In fact, the Code redirection in vim is completed by the vim tags module, and the tags module depends on the tags file. Ctags (Generate tag files
