Why define a partial class?
Use of Partial Classes

If you are working on a bigger project, splitting the files over different classes helps developers work on the same project simultaneously. If you are working on an automatically generated source, then the code can be added to the class without regenerating the source file.All partial-type definitions meant to be parts of the same type must be defined in the same assembly and the same module (.exe or . dll file). Partial definitions can't span multiple modules. The class name and generic-type parameters must match on all partial-type definitions.Partial classes allow breaking a class definition into multiple source files. all the source files must use the same namespace and class name. Also all source files must define the class as a partial.

Can partial class be inherited : In C#, inheritance with partial classes works pretty smoothly. Just ensure all parts of your partial class inherit from the same base class, or implement the same interfaces, breaking this rule might upset the C# compiler! That's it!

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.

What is abstract class vs partial class : An abstract class is a class with at least one method defined as abstract. This type of class cannot be instantiated. An abstract class can have one or more abstract methods and properties and other methods and properties like normal classes. A class defined in two or more files is called a partial class.

Advantages of a partial class

You can separate UI design code and business logic code so that it is easy to read and understand. For example, if you are developing a web application using Visual Studio and adding a new web form then there are two source files, “aspx. cs” and “aspx. designer.

In C#, what is the significance of a sealed partial class A Sealed class is a class that cannot be inherited. A partial class is a class that can be split between 2 or more source files.

Why do we create partial classes in C#

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.A Static class and a Sealed class cannot be inherited. Sealed class cannot be inherited.Advantages of a partial class

A partial class is a construct that supports scenarios in which you are modifying one part of a class definition, and automatic code-generating software—for example, the XAML designer—is also modifying code in the same class. By using a partial class, you can prevent the designer from overwriting your code.

Why abstract class provides partial abstraction : An Abstract class in java may have abstract methods as well as non abstract (concrete/defined) methods. These non abstract methods make it partial abstraction. Whereas In case of an interface, it has abstract methods only.

Why use abstract class instead of normal class : The abstract class in Java enables the best way to execute the process of data abstraction by providing the developers with the option of hiding the code implementation. It also presents the end-user with a template that explains the methods involved.

What is the difference between partial and static class

If you have a class with only class variables and class methods (only static members), you may chose to mark the class as static. A partial class will be aggregated by contributions from several source files. Prevents instantiation, subclassing, instance members, and use as a type.

Classes have the advantage of being reference types — passing a reference is more efficient than passing a structure variable with all its data. On the other hand, structures do not require allocation of memory on the global heap.Partial class allows us to write a class across multiple files in a project. Partial indicates that the parts of the class can be defined in the namespace and all the parts must be used with the partial keyword. if any part is declared as sealed then the whole type is considered sealed.
