F# Constructor

In F#, constructor is somewhat different than other .Net languages. There are always a primary constructor that may or may not have parameters. Scope of these parameters are throughout the class.

You can create a new additional constructor by using new keyword. Body of constructor must invoke the primary constructor specified at the top of the class declaration.

F# Constructor Example

type Employee(name) = 
 class
  do printf "%s" name
 end
let e = new Employee("FSharp")

Output:

FSharp

F# Non-parameterized Constructor

type Employee(id) = 
 class
  new () =				// This is non parameterized constructor
   printf "This is non parametrized constructor" 
   Employee(12) 
   
 end

let e = new Employee()

Output:

This is non parametrized constructor

F# Parameterized Constructor

type Employee (id,name,salary)= 
 class
   let mutable Id= id
   let mutable Name = name
   let mutable Salary = salary 
   member x.Display() =
    printfn "%d %s %0.2f" Id Name Salary  

 end
let a = new Employee(100,"Rajkumar",25000.00)
a.Display()
let a1 = new Employee(101, "john",26000.00)
a1.Display()

Output:

100 Rajkumar 25000.00
101 john 26000.00
