First, explain what Bom is. The full name of BOM is byte order mark. It is not hard to see from its name that it exists to mark byte order. the definition of byte order can be found here because the group in which the

I have been checking a problem on windows over the past few days. In fact, it has little to do with Windows Mobile and Windows Embedded ce, but I also wrote a blog to find the cause.   I added a new feature and modified the design.CodeRestructured

The solution in the previous article is obviously not optimal. First, we found an optimal solution, and used Directory to merge arrays to remove repeated items. The Code is as follows: The effect is as follows:   Using System;Using System.

C # essential tips for code standardization programmers 1. Introduction This article is a set of development specifications for C # programmer and C # developer. Developing a C # program following this specification can bring the following benefits:

To make the query syntax of Linq closer to C # and VB. NET, C #3.0, and VB. NET 9.0-based templates, anonymous methods, and iterators are important components of LINQ, including the following important features: 1. Hide local variables of the type C

First and Single in Linq are often seen in actual work. It is easy to understand from the literal meaning. One is to take the First element in the list, and the other is to get the unique element. If you want to learn more, read this

Document directory   Today, let's take a look at five methods that use the Linq function to join sequences. These five methods can be classified into the following two categories: Similar connections Concat () Union () Connections of

Pure C # Hook implementation To implement system hooks, you can call three Win32 APIs.SetWindowsHookExUsed to set hooks. (Set up a card to check the required information)[DllImport ("user32.dll", CallingConvention = CallingConvention.

Destroy unnecessary data as soon as possible to reclaim memory usage. If COM components and databases are called, close them in time to avoid resource leakage. In fact, the. net program occupies normal memory, and you can ignore it if you are sure

Today, I saw my buddy asked me a question about goto Bubble sorting, but it is useless to implement it with goto: Using System;Using System. Collections. Generic;Using System. Linq;Using System. Text; Namespace DemoMsg{Class Program{Static void Main

The dictionary in. NET is a container used to store multiple groups of "keys and values". The key must have a value and cannot be repeated. The value has no requirements. However, we often need a dictionary that stores "keys and keys". For example,

C # has two types: Value Type and reference type. C # main types are as follows: Category Description Value Type Simple Type Signed integer:Sbyte, short, int, long Unsigned integer:Byte, ushort, uint, ulong

Unlike c ++, there is no multi-inheritance, which makes people feel happy ...... At least I think so (Multi-inheritance makes code difficult to understand and debug. Of course, multi-inheritance also has its advantages, such as being more flexible ).

By the way, after playing the blog for a while, I have been posting a relatively basic C # knowledge. After the basic post is complete, I will continue to post some articles about the project, I am still studying and have errors and deficiencies.

In C #, use lock and Monitor to control the use of resources by multiple threads. The most common producer and consumer problems are typical examples of multi-thread synchronization and communication. This article uses examples to understand the
