c#使用属性封装

1、使用属性封装方法

AccessModifer Type PropertyName
{
get{...}
set{...}
}

public int {
get{ return this.X}
set{this.x=rangeCheckX(value)}
}

2、属性对某个字段封装时，命名规则，首字母大写

private int employeeID;
public int EmployeeID
{
get{return this.EmployeeID;};
set{this.EmployeeID=value}
}

3、接口中定义属性

interface IScreenPosition

{

int X{get;set;}

int Y{get;set;}

}

4、实例化同时赋值

static void DoWork()
        {
            Polygon square = new Polygon();
            Polygon triangle = new Polygon { NumSides = 3 };
            Polygon pentagon = new Polygon { SideLength = 15.5, NumSides = 5 };

            Console.WriteLine("Square: number of sides is {0}, length of each side is {1}", 
                square.NumSides, square.SideLength);
            Console.WriteLine("Triangle: number of sides is {0}, length of each side is {1}", 
                triangle.NumSides, triangle.SideLength);
            Console.WriteLine("Pentagon: number of sides is {0}, length of each side is {1}", 
                pentagon.NumSides, pentagon.SideLength);
        }
