Question

In C#, if I have an inherited class with a default constructor, do I have to explicitly call the base class’ constructor or will it be implicitly called?

class BaseClass {     public BaseClass()     {         // ... some code     } } class MyClass : BaseClass {     public MyClass() // Do I need to put ': base()' here or is it implied?     {         // ... some code     } }

You do not need to explicitly call the base constructor, it will be implicitly called.

Extend your example a little and create a Console Application and you can verify this behaviour for yourself:

using System;  namespace ConsoleApplication1 {     class Program     {         static void Main(string[] args)         {             MyClass foo = new MyClass();              Console.ReadLine();         }     }      class BaseClass     {         public BaseClass()         {             Console.WriteLine('BaseClass constructor called.');         }     }      class MyClass : BaseClass     {         public MyClass()         {             Console.WriteLine('MyClass constructor called.');         }     } }
