用C#写下面这个题.....谢谢

描述平面坐标的类，其中包含两个私有成员，分别是点的x坐标和y的坐标，为私有成员编写属性过程，添加有参数和无参数的构造函数，在Main()主函数中生成类对象，并输出类的坐标值。

 public class Point
 {
     private float x;
     private float y;

     public float X
     {
            get{return x;}
            set{x=value;}
     }
     public float Y
     {
            get{return y;}
            set{y=value;}
     }

     public Point()
     {
            x=0;
            y=0;
     }

     public Point(float x,float y)
     {
            this.x=x;
            this.y=y;
     }
 }

 void main()
 {
     Point p=new Point(1,2);
     console.WriteLine(p.X.ToString());
     console.WriteLine(p.Y.ToString());
 }

public class Point
{
private float x;
private float y;

 public float X
 {
        get{return x;}
        set{x=value;}
 }
 public float Y
 {
        get{return y;}
        set{y=value;}
 }

 public Point()
 {
        x=0;
        y=0;
 }

 public Point(float x,float y)
 {
        this.x=x;
        this.y=y;
 }

}

void main()
{
Point p=new Point(1,2);
console.WriteLine(p.X.ToString());
console.WriteLine(p.Y.ToString());
}
