What are the functions of “partial” in C#?

In C#, the ‘partial’ keyword is used to split the definition of a class, struct, or interface into multiple parts. Here are some functionalities of ‘partial’:

1. Definitions of classes, structures, or interfaces can be split into multiple source files to facilitate collaboration among multiple developers or organize code structure.
2. “By dispersing the different functions or members of a class, struct, or interface across multiple files, it can enhance code readability and maintainability.”
3. Separating automatically generated code from handwritten code can facilitate the use of code generation tools.
4. Defining private members in one section and public members in another can enhance the encapsulation of the code.
5. You can use the partial method in one part and implement it in another, making it easier to write and maintain the functionality of methods in different files.

It is important to note that the “partial” keyword can only be used in the definition of classes, structures, and interfaces, and cannot be used with other types such as enums or delegates. Additionally, the parts of a partial class are merged into a complete class during compilation.
