Detailed explanation of the Builder generator mode in C# to solve the problem of configuring the computer-C#.Net Tutorial-php.cn

This article mainly introduces the Builder pattern of the C# design pattern to solve the problem of configuring a computer with my wife. It briefly introduces the concept and function of the generator pattern and combines it with specific examples to analyze how the C# generator pattern solves the problem of configuring a computer. For the steps and related operation skills, friends in need can refer to the following

This article describes the example of the Builder generator mode of the C# design pattern to solve the problem of configuring a computer with my wife. Share it with everyone for your reference, the details are as follows:

1. Theoretical definition

The generator mode is also called: builder mode, it can Create a complex object in steps.

2. Application Examples

Description of requirements: Now that I have paid my salary, I plan to go to Gangding Bainaohui to configure a computer for my wife.
OK, take the BRT and set off.
When I reached the top of the post, a beautiful woman came to me with a smile: Sir, which brand do you like? Come and take a look!
Everyone has spoken, and it’s hard to refuse such hospitality, so let’s take a look.

21. Running results

22. Summary

I originally wanted to refine each computer accessory, but found that the project was very large and the computer products had many attributes, so I only listed 2 fields.

The attachment includes the program source code. It also includes tests for other projects, including console and web.
