接口不是类。 不要像类那样的用。 下面有个范例代码,您可以参看:// keyword_interface.cs // Interface implementation using System; interface IPoint { // Property signatures: int x { get; set; } int y { get; set; } }class MyPoint : IPoint { // Fields: private int myX; private int myY; // Constructor: public MyPoint(int x, int y) { myX = x; myY = y; } // Property implementation: public int x { get { return myX; } set { myX = value; } } public int y { get { return myY; } set { myY = value; } } }class MainClass { private static void PrintPoint(IPoint p) { Console.WriteLine("x={0}, y={1}", p.x, p.y); } public static void Main() { MyPoint p = new MyPoint(2,3); Console.Write("My Point: "); PrintPoint(p); } }
