namespace structAndclass
{
class Program
{
static void Main(string[] args)
{
// 区别： struct 在传递的时候，传递是一个副本，并没有修改原始对象
// class 在传递的时候传递的是对原始对象的引用,修改原始对象的值

        StructModifyPoint structModifyPoint = new StructModifyPoint();        structModifyPoint.y = 10;        structModifyPoint.x = 10;        Console.WriteLine("----------Struct--------");        // values are 10,10        Console.WriteLine("Initial values are :{0},{1}",structModifyPoint.x,structModifyPoint.y);        Console.WriteLine("Insurt structChangePoint():");        // values are 20,20        structChangePoint(structModifyPoint);        // values are 10,10        Console.WriteLine("After Modify,struct values are:{0},{1}", structModifyPoint.x, structModifyPoint.y);        ClassModifyPoint classModifyPoint = new ClassModifyPoint();        classModifyPoint.y = 10;        classModifyPoint.x = 10;        Console.WriteLine("----------Class--------");        // values are 10,10        Console.WriteLine("Initial values are :{0},{1}", classModifyPoint.x, classModifyPoint.y);        Console.WriteLine("Insurt classChangePoint():");        // values are 20,20        classChangePoint(classModifyPoint);        // values are 20,20        Console.WriteLine("After Modify,class values are:{0},{1}", classModifyPoint.x, classModifyPoint.y);        Console.ReadKey();    }    //struct    public static   void structChangePoint(StructModifyPoint point)    {        point.x += 10;        point.y += 10;        Console.WriteLine("structChangePoint inner values are:{0},{1}",point.x,point.y);    }    //class    public  static void classChangePoint(ClassModifyPoint point)    {        point.x += 10;        point.y += 10;        Console.WriteLine("classChangePoint inner values are:{0},{1}", point.x, point.y);    }}//结构体

public struct StructModifyPoint
{
public int x;
public int y;
public StructModifyPoint(int x,int y)
{
this.x = x;
this.y = y;
}

}//类

public class ClassModifyPoint
{
public int x;
public int y;
public ClassModifyPoint()
{

    }    public ClassModifyPoint(int x, int y)    {        this.x = x;        this.y = y;    }}
