Explain PARTIAL CLASS.

 PARTIAL CLASS

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

• When working on large projects, spreading a class over separate files enables multiple programmers to work on it at the same time. When working with an automatically generated source, code can be added to the class without having to recreate the source file. Visual Studi uses this approach when it creates Windows Forms, Web service wrapper code, and so on.

• To split a class definition, use the partial keyword modifier, as shown here: 

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 Print Coords()

{

Console.WriteLine("Coords: (0), (1)", x, y);

}

class TestCoords

{

static void Main() 

{

Coords myCoords new Coords(10, 15); 

myCoords. Print Coords();

// Keep the console window open in debug mode. Console.WriteLine("Press any key to exit.");

Console.ReadKey();

}

} //Output: Coords: 10,15
