当您想创建类似的东西时，接口是非常好的：
using System;
namespace MyInterfaceExample
{
public interface IMyLogInterface
{
//I want to have a specific method that I'll use in MyLogClass
void WriteLog();
}
public class MyClass : IMyLogInterface
{
public void WriteLog()
{
Console.Write("MyClass was Logged");
}
}
public class MyOtherClass : IMyLogInterface
{
public void WriteLog()
{
Console.Write("MyOtherClass was Logged");
Console.Write("And I Logged it different, than MyClass");
}
}
public class MyLogClass
{
//I created a WriteLog method where I can pass as a parameter any object that implements IMyLogInterface.
public static void WriteLog(IMyLogInterface mylogobject)
{
mylogobject.WriteLog(); //So I can use WriteLog here.
}
}
public class MyMainClass
{
public void DoSomething()
{
MyClass aClass = new MyClass();
MyOtherClass otherClass = new MyOtherClass();
MyLogClass.WriteLog(aClass);//MyClass can log, and have his own implementation
MyLogClass.WriteLog(otherClass); //As MyOtherClass also have his own implementation on how to log.
}
}
}
在我的示例中，我可以是一名编写人员的开发人员MyLogClass，而其他开发人员可以创建他们的类，并且当他们想要登录时，他们可以实现接口IMyLogInterface。就像他们问我要使用的WriteLog()方法需要实现什么一样MyLogClass。他们将在界面中找到答案。
