What is Partial Class?

Answer:

Partial class

Instead of defining an entire class, you can split the definition into multiple classes by using the partial keyword. When the application is complied, the C# complier will group all the partial classes together and treat them as a single class. There are a couple of good reasons to use partial classes. Programmers can work on different parts of a class without needing to share the same physical file. Also you can separate your application business logic from the designer-generated code.

C#

Public partial class Employee

{

      public void DoWork()

      {}

}



Public partial class Employee

{

       public void GoToLunch()

       {}

}
