C# Constructor Calling

A constructor can invoke/call from base class using the base keyword.

public Manager(int initialdata) : base() //Base contructor without parameter
{
    //Add further instructions here.
}
public Manager(int annualSalary):base(annualSalary) //Base contructor with parameter
    {
        //Add further instructions here.
    }


A constructor can invoke/call another constructor in the same object using the this keyword.



//First Contructor
public Employee(int annualSalary)
{
    salary = annualSalary;
}

//Second Contructor
public Employee(int weeklySalary, int numberOfWeeks)
: this(weeklySalary * umberOfWeeks) //Call First Contruct after call this method.
{
//Add further instructions here.
}
