[Csharp] most programmers use the bubble algorithm when writing sorting algorithms. Why? This algorithm is the simplest, easier to understand, and easier to write. However, the bubble algorithm is not efficient. Today, we will write a c # Quick

The basic data type of. C # is fixed and does not change. It is different from C ++. Integer types are usually faster than smaller types, because the CPU has been optimized for integer types and memory alignment exists .. C # to convert A char to an

To use the design pattern, you must first understand the object, inheritance, and interface. Generally, we use the new method when creating the object, which is related to how the program creates the object. Further thinking, we often need to create

Break statement:The break statement causes the running program to immediately exit the loop contained in the innermost layer or exit a switch statement. Because it is used to exit a loop or switch statement, this form of break statement is valid

I started to think this way about programming, but it is better for us now. For example, when the language develops, it becomes easier to understand and program. tools also develop, making programming easier, such as smart prompts. However, this

Apps are often used in projects. some of the config files are automatically generated, such as those generated when the webservice or wcf Service is referenced, and some manually created configuration files are directly named app by default. config.

Since the c # Video is used to aid the learning of the design model, the content of this part is also the same as that of VB. although it was difficult at the beginning. after accessing some examples and experiments. it becomes much smoother to

I. Overview In software development, we sometimes encounter many objects interacting with each other. There is a complex reference relationship between objects. It is very difficult to modify the system when the requirement is changed. To decouple

From the Internet, we can see that the data inserted by excel is very slow. Someone writes data to excel through a stream, which is very fast. The detailed principle is as follows: 1. StreamWriter sw = new StreamWriter (path, false, Encoding.

Due to project requirements, the project needs to be compressed in C #, then decompressed in java, or reversed, compressed in Java, decompressed in C #. The following code has been tested and verified. Key Technical Points and experiences: The

Recently, when I was working on a project, the developed winform can be normally displayed on my computer. If I share it with another computer, I cannot display it: 1. When the resolution of the two computers is the same, the display cannot be

Several of my friends who used the previous development framework used it in the project also gave me valuable comments. Although there have been no updates recently, I have made some suggestions for my friends, I have carefully reviewed and made

If the attribute is a string, int, or other class, the attribute is modified during design and saved during runtime. If the property is a control, such as Label, the property is changed during design and restored during runtime, you can

During coding, since we started to perform simple testing and development under winform, we wanted to divide the code into different classes because we had more code, however, because the original test is in the same form, it is very convenient for
