Algorithm

In C#, a partial class is a class that can be split into multiple source files. Each source file contains a portion of the class definition, and all the parts are combined at compile time to create a single class. This feature is useful when you want to organize a large class into multiple files or when you need to separate auto-generated code from your custom code.
