What is a partial class and what can it be used for?
A partial class is a special feature of C#. It provides a special ability to implement the functionality of a single class into multiple files and all these files are combined into a single class file when the application is compiled. A partial class is created by using a partial keyword.
Can partial class be inherited?
All the parts of a partial class must be prefixed with the partial keyword. If you seal any specific part of a partial class, then the entire class is sealed; the same as in an abstract class. Inheritance cannot be applied to partial classes.
How do you implement a partial method?
In order to create a partial method, it must be declared first(like an abstract method), with a signature only and no definition. After it is declared, its body can be defined in the same component or different component of the partial class/struct . A partial method is implicitly private.
What does partial mean C#?
The partial keyword indicates that other parts of the class, struct, or interface can be defined in the namespace. All the parts must use the partial keyword. All the parts must be available at compile time to form the final type. All the parts must have the same accessibility, such as public , private , and so on.
What is the use of partial methods?
A partial method has its signature defined in one part of a partial type, and its implementation defined in another part of the type. Partial methods enable class designers to provide method hooks, similar to event handlers, that developers may decide to implement or not.
