I have been reviewing the basic knowledge of C # Over the past few days, and I have also found that I have not understood and confused the concept before. Now I will share my Notes: 1. What are the important components of the. NET platform? 1) FCL

1. NGen.exe tool, which can compile the IL code into local code when a program is installed on the user's computer. Since the code has been compiled during installation, the clr jit compiler does not need to compile the IL code at runtime, which

XmlDocument xmlDoc = new XmlDocument(); xmlDoc.Load("cmdCfg.xml"); XmlNodeList nodeList = xmlDoc.SelectSingleNode("config").ChildNodes; if (nodeList != null) { foreach (XmlNode cmdNode in

In the previous six articles, I have introduced in detail the algorithms related to the lexical analyzer. They all focus on implementation details and may be messy. This article introduces how to define lexical analyzer as a whole and how to

3Des implements three DES encryption algorithms for each data block, which is a safer form of DES. 3DES is safer than the original DES. It's all clear. The following is the source code for encryption and decryption. ECB mode. 1 public class _ 3

As an application framework, Spring.net provides many flexible and rich functions (such as dependency injection, aop, data access abstraction, and asp.net extension) for enterprise-level. net applications ). Inversion of Control (IoC) is a design

C # The discussion of Multi-inheritance seems to be an old question, but today this article will show you that C # multi-inheritance may be something you have never heard, people who even invented the C # language never thought that I would write

I. Syntax features 1. using introduces the type of using keyword in. NET. Here it refers to the introduction of namespace. It is very convenient to support the using type, for example: using System. runtime. interopServices. marshall; // you can

Algorithms are a huge topic. STL contains more than 100 algorithms. It is very painful to remember the algorithm name. So here I will narrow down the scope: I will mainly discuss the traversal, sorting, and searching algorithms in STL algorithms.

C # automatically generate beautiful crystal effect portraits Similar to other Weibo systems, However, the avatar of "more intranets and microblogs" can be more beautiful, because the system achieves the crystal effect.C # The program implements the

Main Content   I recently encountered an algorithm problem in the Chuanzhi forum. I think there is an interesting solution. The following calculation method may not be optimal, but you can refer to it.Problem: ========================================

The String. Replace (string, string) method in C # replaces all the matching items, but sometimes we need to Replace the first matching item. I will write another method here to implement this function. Please advise:  Replace (source, match, []
