C # BASIC language knowledge (5): Partial Class Classification

Partial class, Category or distribution class. As the name implies, a class is divided into multiple parts. For example, a class has three methods. In VS 2005, three methods in the class are stored in three different. CS files.
Benefits:
1. A large project class can be divided into different blocks and written by different programmers at the same time.
2. if the source is automatically generated by the system, you can add it with an independent partial class without having to change it to the original class.
3. When a class is large, you can use partial class for functional division, which is also a good classification method.

If you are developing a project's public function library, the richer the content for the public function library, the better, but it cannot be written at once. You need to accumulate at, then you can use partial class, upload the newly developed partial class program to the server or a specific directory at intervals. instead of copying and pasting the new code into the original program code, reduce unnecessary troubles.

Example: Define the example class as partial class, and define the three methods M1, M2, and m3 of the class in the example1.cs, example2.cs, and example3.cs class files respectively, and then in the partialclass. aspx. instantiate the example class in Cs and call the methods in the class.
