问题描述
多态是重载的另一种说法吗?
Is polymorphism another term for overloading?
推荐答案
No;重载是用不同数量的参数创建一个具有相同名称的方法,或者使用其他类型的参数.
No; overloading is creating a method with the same name with a different amount of parameters, or with parameters which are of another type.
多态性是关于跨各种类型(都具有相同的基本类型")更改特定方法的实现/功能.
Polymorphism is about changing the implementation / functionality of a specific method across various types (which all have the same 'base-type').
重载:
public class TestClass
{
public void DoSomething( int a, int b ) {}
public void DoSomething( int a, int b, string x ) {}
}
多态性:
public abstract class Base
{
public abstract DoSomething();
}
public class A : Base
{
public override DoSomething()
{
Console.WriteLine("I am A");
}
}
public class B : Base
{
public override DoSomething()
{
Console.WriteLine("I am B");
}
}
