How to calculate the area of images with different shapes by C #
This article mainly introduces "how C# calculates the area of images of different shapes". In daily operation, I believe many people have doubts about how to calculate the area of images of different shapes in C#. The editor consulted all kinds of data and sorted out a simple and easy-to-use method of operation. I hope it will be helpful to answer the question of "how to calculate the area of images of different shapes in C#". Next, please follow the editor to study!
The following program demonstrates using the virtual method area () to calculate the area of images of different shapes:
Using System
Namespace PolymorphismApplication
{
Class Shape
{
Protected int width, height
Public Shape (int aversion 0, int bread0)
{
Width = a
Height = b
}
Public virtual int area ()
{
Console.WriteLine ("area of parent class:")
Return 0
}
}
Class Rectangle: Shape
{
Public Rectangle (int axi0, int bacc0): base (a, b)
{
}
Public override int area ()
{
Console.WriteLine ("area of Rectangle class:")
Return (width * height)
}
}
Class Triangle: Shape
{
Public Triangle (int a = 0, int b = 0): base (a, b)
{
}
Public override int area ()
{
Console.WriteLine ("area of Triangle class:")
Return (width * height / 2)
}
}
Class Caller
{
Public void CallArea (Shape sh)
{
Int a
A = sh.area ()
Console.WriteLine (area: {0}, a)
}
}
Class Tester
{
Static void Main (string [] args)
{
Caller c = new Caller ()
Rectangle r = new Rectangle (10,7)
Triangle t = new Triangle (10,5)
C.CallArea (r)
C.CallArea (t)
Console.ReadKey ()
}
}
}
When the above code is compiled and executed, it produces the following results:
Area of Rectangle class: area of 70Triangle class: area: 25 so far, the study on "how to calculate the area of images of different shapes in C#" is over. I hope to be able to solve your doubts.
