【转载】Derived Classes Do Not Inherit Constructors

A derived class inherits all of the members of a base class except for its constructors.

You must define a constructor in a derived class unless the base class has defined a default (parameterless) constructor.  If you don’t define a constructor in the derived class, the default constructor in the base class is called implicitly.

When you define a constructor in a derived class, you can call a constructor in the base class by using the base keyword.

Here’s an example:

 1 public class Dog
 2 {
 3     public string Name { get; set; }
 4     public int Age { get; set; }
 5 
 6     public Dog(string name, int age)
 7     {
 8         Name = name;
 9         Age = age;
10     }
11 }
12 
13 public class Terrier : Dog
14 {
15     public string Attitude { get; set; }
16 
17     // Call the Name/Age constructor in the base class
18     public Terrier(string name, int age, string attitude)
19         : base(name, age)
20     {
21         Attitude = attitude;
22     }
23 }
