This article mainly explains "how to draw the specified shape of C#". The content of the explanation in the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought. Let's study and learn "how to draw a specified shape in C#"!

The following example creates the Shape base class and the derived classes Circle, Rectangle, Triangle, and the Shape class provides a virtual method called Draw that is overridden in each derived class to draw the specified shape of the class.

Using System

Using System.Collections.Generic

Public class Shape

{

Public int X {get; private set;}

Public int Y {get; private set;}

Public int Height {get; set;}

Public int Width {get; set;}

/ / Virtual method

Public virtual void Draw ()

{

Console.WriteLine ("perform drawing tasks of the base class")

}

}

Class Circle: Shape

{

Public override void Draw ()

{

Console.WriteLine ("draw a circle")

Base.Draw ()

}

}

Class Rectangle: Shape

{

Public override void Draw ()

{

Console.WriteLine (draw a rectangle)

Base.Draw ()

}

}

Class Triangle: Shape

{

Public override void Draw ()

{

Console.WriteLine ("draw a triangle")

Base.Draw ()

}

}

Class Program

{

Static void Main (string [] args)

{

/ / create a List object and add Circle, Triangle and Rectangle to the object

Var shapes = new List

{

New Rectangle ()

New Triangle ()

New Circle ()

}

/ / use the foreach loop to iterate through the derived classes of the list and call the Draw method on each Shape object in it

Foreach (var shape in shapes)

{

Shape.Draw ()

}

Console.WriteLine ("Press any key to exit.")

Console.ReadKey ()

}

}

When the above code is compiled and executed, it produces the following results:

Draw a rectangle to execute the drawing task of the base class, draw a triangle to execute the drawing task of the base class, draw a circle to execute the drawing task of the base class, press any key to exit Thank you for reading, the above is the content of "how to draw the specified shape of C#". After the study of this article, I believe you have a deeper understanding of the problem of how to draw the specified shape of C#. The specific use of the situation also needs to be verified in practice. Here is, the editor will push for you more related knowledge points of the article, welcome to follow!
