有人可以解释C＃中接口的确切用法吗？

Can someone explain the exact use of interfaces in C#?

答

想象一下创建汽车的工厂的情况。你知道每辆车都有一个引擎，可以启动，所以你有以下几点：

Imagine the the situation of having a factory that creates cars. You know that every vehicle has an engine and can be started, so you have the following:

interface IVehicle
{
   Engine vehicleEngine { get; set; }

   bool StartEngine();
}

现在，工厂制造了一系列其他车辆，例如一辆卡车和普通汽车：

Now, the factory makes an array of other vehicles, so for instance a truck and a normal car:

public Car : IVehicle
{
   // MUST implement vehicleEngine and StartEngine:

   public Engine vehicleEngine { get; set; }

   public bool StartEngine()
   {
       // Cars needs to do xyz to start
   }

   public int MaxNumberOfPassenger { get; set; } // Specific to Car
}

然后：

public Truck : IVehicle
{
   // MUST implement vehicleEngine and StartEngine:

   public Engine vehicleEngine { get; set; }

   public bool StartEngine()
   {
       // Trucks needs to do abc to start
   }

   public int MaximumLoad { get; set; } // Specific to Truck
}

因此，这迫使所有车辆实施特定会员属于车辆类别，但也可以专门与他们自己的独特成员。

This therefore forces all vehicles to implement specific members to fall under the category of a vehicle, but then can also be specialized with their own distinct members.
