C#学习笔记(三)

1.内部类和外部类

在这里举个栗子，什么是内部类，什么是外部类

class OutClass{
    public class InnerClass{
        private int UserName{
            get;set;
        }
        private int PassWord{
            get;set;
        }
         
        public void Show()
        {
            System.Console.WriteLine(UserName+PassWord);
        }
    }
}
 
class Program{
    public static void Main(string[] agrs)
    {
        OutClass.InnerClass in=new OutClass.InnerClass();
         
        in.UserName='root';
        in.PassWord='123';
        in.Show();
    }
}

　　可以很明显的看出，内部类可以当成外部类一样使用，只是需要注意其访问范围

2.部分类

public partial class Person{
    public int Age{
        get;set;
    }
     
    public int Name{
        get;set;
    }
}
 
public partial class Person{
    public string getInfo(){
        return Age.ToString()+Name;
    }
}
 
class Program{
    public static void Main(string[] agrs)
    {
        Person person=new Person();
         
        person.Age=22;
         
        person.Name="zs";
         
        System.Console.WriteLine(person.getInfo());
    }
}
