Params is a keyword in C # development language, Params is mainly used when passing parameters to the function, that is, when the parameters of the function are not fixed. After the params keyword in the method declaration, no other parameters are

Baidu does not use xhtml, which makes the original XML function of. NET not so easy to use. (And who will really like DOM? It's so tiring to use !)   However, Baidu's page is very irregular, so it is imperative to use a large number of hard encoding.

Problem Source: in c # programming, some numeric primitive types such as Int16, Int32, Int64, and Decimal are often involved in addition, subtraction, multiplication, division, and so on. For example, we often write the following method, which is

Using System;Using System. Xml;Namespace WLERP. Common. Util{/// /// Xml operation tool class/// Public sealed class XmlUtil{Private XmlUtil (){}/// /// Create a node/// /// /// /// Public static XmlNode AppendElement (XmlNode node, string

I have been learning C # For a long time, read books, and then read more blogs on the Internet, then I learned to make a Demo of a small function like the QQ tray icon: (1) Click the close button in the window or display the tray when minimized; (2)

ExecuteReader: Records of one table can be read but not written. ExecuteScalar: Only one record can be read. It is generally used to determine whether a database has data. It can only be read but not written. ExecuteNonQuery: can be written to read,

This article mainly summarizes the application of C # enumeration in my actual project. If there are any deficiencies, you are welcome to point out. I. Basic Application of enumeration 1. enumeration can be understood as a constant combination or a

There are always some exceptions that we could not expect when writing code. What we need to do is to record them. The following is a sample code: // Catch the current unbound exception AppDomain. CurrentDomain. UnhandledException + = new

To select the correct set, we must first understand some data structure knowledge. The so-called data structure is a set of data elements with one or more specific relationships between each other. Let's take a look at the classification of the set.

1: Ensure the thread security of the Set If. net4.0 is used, a new thread security collection class is available.The new System. Collections. Concurrent namespace introduces multiple new thread-safe collection classes, which can provide lock-free

Chapter 2 Basic Sorting Algorithm The two most common operations for data storage on a computer are sorting and searching. Since the beginning of the computer industry, this is clear, so sorting and searching are the two most widely studied

In the previous article, we introduced C # as a fully object-oriented language. Since it is a fully object-oriented language, we should use the object-oriented model to learn C #, do not know about object orientation? Don't worry. This article will

Okay, I admit that this is a title. The actual situation is: I cannot find a reason why I cannot use ICloneable. In fact, the interface ICloneable may cause misunderstanding because it only has one Clone method. We all know that object copying can

As mentioned above, each thread has its own resources, but the code zone is shared, that is, each thread can execute the same function. This may cause several threads to execute a function at the same time, resulting in data confusion and unexpected
