How to call a base constructor in C#?

Question

Aryan Kumar · Answer

To call a base constructor in C#, you can use the base() keyword. The base() keyword takes the parameters of the base constructor as a parameter.

For example, the following code calls the BaseClass() constructor from the DerivedClass() constructor:

C#

class BaseClass
{
    public BaseClass()
    {
        // This is the base class constructor.
    }
}

class DerivedClass : BaseClass
{
    public DerivedClass()
    {
        // This constructor calls the base class constructor.
        base();

        // This constructor also does other things.
    }
}

When the DerivedClass() constructor is called, the base() keyword calls the BaseClass() constructor first. Then, the DerivedClass() constructor does other things.

Here is an explanation of the code:

The base() keyword is used to call the BaseClass() constructor.
The BaseClass() constructor is the base class constructor for the DerivedClass class.
The DerivedClass() constructor takes no parameters.
The DerivedClass() constructor calls the base() keyword to call the BaseClass() constructor.
The DerivedClass() constructor also does other things.
