下面程序运行的结果是： public struct myPoint { public int X, Y; public myPoint（int x, int y

下面程序运行的结果是： public struct myPoint { public int X, Y; public myPoint(int x, int y) { X = x; Y = y; } public myPoint(int x) : this(x, default(int)) { X = x; } public void show() { Console.Write("x={0},y={1}", X, Y); } } class testA { static void Main() { myPoint p1 = new myPoint(2); myPoint p2 = new myPoint(1, 2); p1 = p2; p1.Y = 10; p1.show(); p2.show(); } }
