It is possible to split the definition of a class or a struct, or an interface over two or more source files. Each source file contains a section of the class definition, and all parts are combined when the application is compiled.

It is possible to split the definition of a class or a struct, or an interface over two or more source files. Each source file contains a section of the class definition, and all parts are combined when the application is compiled. There are several situations when splitting a class definition is desirable: When working on large projects, spreading a class over separate files allows multiple programmers to work on it simultaneously. public partial class CoOrds { private int x; private int y; public CoOrds(int x, int y) { this.x = x; this.y = y; } } public partial class CoOrds { public void PrintCoOrds() { System.Console.WriteLine("CoOrds: {0},{1}", x, y); } } class TestCoOrds { static void Main() { CoOrds myCoOrds = new CoOrds(10, 15); myCoOrds.PrintCoOrds(); } }

The purpose of partial classes is to allow a class's definition to span across multiple files Pawan Tiwari Senior Software engineer 07814140365 My Blog

Partial classes can improve code readability and maintainability by providing a powerful way to extend the behavior of a class and attach functionality to it.

A Partial class is a class that can be split into two or more classes. This means that a class can be physically separated into other parts of the class within the same namespace. All the parts must use the partial keyword. All the other classes should also have the same access modifier. At the compile time, all the partial classes will be treated as a single class. Let us list some advantages of having partial classes. • Allows a clean separation of business logic layer and the user interface. • The UI code can be hidden from the developer. • Makes the debugging easier.

• Partial Class It’s a keyword where classes, struct and interface can use it for span across multiple files like Generating a part of a class SO THAT multiple files can be beneficial.
