什么是接口隔离原则?如何在 C# 中实现它?

客户端不应被迫依赖它们不使用的接口。
接口隔离原则指出，客户端不应被迫实现它们不使用的接口。
与其使用一个庞大的接口，不如基于方法组构建多个小型接口，每个接口服务于一个子模块。
接口隔离之前
示例
public interface IProduct {
int ID { get; set; }
double Weight { get; set; }
int Stock { get; set; }
int Inseam { get; set; }
int WaistSize { get; set; }
}
public class Jeans : IProduct {
public int ID { get; set; }
public double Weight { get; set; }
public int Stock { get; set; }
public int Inseam { get; set; }
public int WaistSize { get; set; }
}
public class BaseballCap : IProduct {
public int ID { get; set; }
public double Weight { get; set; }
public int Stock { get; set; }
public int Inseam { get; set; }
public int WaistSize { get; set; }
public int HatSize { get; set; }
}
接口隔离之后
示例
public interface IProduct {
int ID { get; set; }
double Weight { get; set; }
int Stock { get; set; }
}
public interface IPants {
int Inseam { get; set; }
int WaistSize { get; set; }
}
public interface IHat {
int HatSize { get; set; }
}
public class Jeans : IProduct, IPants {
public int ID { get; set; }
public double Weight { get; set; }
public int Stock { get; set; }
public int Inseam { get; set; }
public int WaistSize { get; set; }
}
public class BaseballCap : IProduct, IHat {
public int ID { get; set; }
public double Weight { get; set; }
public int Stock { get; set; }
public int HatSize { get; set; }
}
