C # Use of the partial keyword,

C #2.0 introduces the concept of local types. The local type allows us to divide a class, structure, or interface into several parts, which are implemented in several different. cs files.

The local type applies to the following situations:

(1) The type is very large and should not be implemented in a file.
(2) A part of the code in a type is the code generated by the automation tool, and should not be mixed with the code we write.
(3) many people need to work together to compile a class.

Example:

Write the instance of class2 in the same namespace and add the keyword partial

 

Write the instance of class2 in the class3 class with the keyword partial

In main, we can see that it is compiled at the same time in each part.
