Invoking Base Class Constructor [Resolved]

[Kezmondo]

I'm very new to C# and have a quick question...

When a class is derived from a base class, is the base class constructor always invoked when an instance of the derived class is created, regardless of whether ": base()" is added to the derived class constructor?


e.g I have a "Control" class, and a "Listbox" class which dervies from it.
When I create an instance of "Listbox", is the "Control" constructor always invoked?

Thanks...

It calls the default constructor automaticaly. If you need to call an other constructor, then you have to do it manualy. A test like this reveals it.

using System;

namespace testbase{

	class Class1{

		static void Main(string[] args){
			
			Class2 test1 = new Class2();
			Class3 test2 = new Class3();
			Class2 test3 = new Class3();

			Console.WriteLine("test1: " + test1.hello);
			Console.WriteLine("test2: " + test2.hello);
			Console.WriteLine("test3: " + test3.hello);

			Console.ReadLine();
		}
	}



	class Class2{

		public string hello;


		public Class2(){
			hello = "hello";
		}
	}



	class Class3 : Class2{

		public Class3(){

		}

	}
}
