C# 中的类

数据类型的蓝图就是您在 C# 中可以称为类的东西。对象是类的实例。构成类的方法和变量称为类的成员。
示例
以下是 C# 中类的一般形式−
<access specifier> class class_name {
// 成员变量
<access specifier><data type> variable1;
<access specifier><data type> variable2;
...
<access specifier><data type> variableN;
// member methods
<access specifier><return type> method1(parameter_list) {
// method body
}
<access specifier><return type> method2(parameter_list) {
// method body
}
...
<access specifier><return type> methodN(parameter_list) {
// method body
}
}
Let us see an example to learn how to create a class in C# −
示例
using System;
namespace Demo {
class Box {
public double length; // Length of a box
public double breadth; // Breadth of a box
public double height; // Height of a box
}
class Boxtester {
static void Main(string[] args) {
Box Box1 = new Box(); // Declare Box1 of type Box
Box Box2 = new Box(); // Declare Box2 of type Box
double volume = 0.0; // Store the volume of a box here
// box 1 specification
Box1.height = 5.0;
Box1.length = 6.0;
Box1.breadth = 7.0;
// box 2 specification
Box2.height = 10.0;
Box2.length = 12.0;
Box2.breadth = 13.0;
// volume of box 1
volume = Box1.height * Box1.length * Box1.breadth;
Console.WriteLine("Volume of Box1 : {0}", volume);
// volume of box 2
volume = Box2.height * Box2.length * Box2.breadth;
Console.WriteLine("Volume of Box2 : {0}", volume);
Console.ReadKey();
}
}
}
输出
Volume of Box1 : 210 Volume of Box2 : 1560
