Note one thing here: we are not making any explicit call to the constructor of base class neither by initializer nor by the base keyword, but it is still executing. This is the normal behavior of the constructor.

An Intro to Constructors in C#http://www.codeproject.com/KB/dotnet/ConstructorsInCSharp.aspx
public class myBaseClass
{
public myBaseClass()
{
// Code for First Base class Constructor
}

public myBaseClass(int Age)
{
// Code for Second Base class Constructor
}

// Other class members goes here
}

public class myDerivedClass : myBaseClass
// Note that I am inheriting the class here.
{
public myDerivedClass()
{
// Code for the First myDerivedClass Constructor.
}

public myDerivedClass(int Age):base(Age)
{
// Code for the Second myDerivedClass Constructor.
}

// Other class members goes here
}
Now, what will be the execution sequence here:

If I create the object of the derived class as:

myDerivedClass obj = new myDerivedClass()
Then the sequence of execution will be:

public myBaseClass() method.
and then public myDerivedClass() method.
