Discriminated unions in F# allow for defining types that can take on different forms. This is a powerful feature that can be challenging to translate into C#, which does not have a direct equivalent.
F# Example:
type Shape =
| Circle of float
| Rectangle of float * float
C# Equivalent:
class Shape
{
public class Circle
{
public float Radius { get; }
public Circle(float radius) => Radius = radius;
}
public class Rectangle
{
public float Width { get; }
public float Height { get; }
public Rectangle(float width, float height)
{
Width = width;
Height = height;
}
}
}

Pattern matching in F# is a powerful feature that allows for concise and expressive handling of different data types.
F# Example:
match shape with
| Circle r -> printfn "Circle with radius %f" r
| Rectangle (w, h) -> printfn "Rectangle with width %f and height %f" w h
C# Equivalent:
switch (shape)
{
case Circle c:
Console.WriteLine($"Circle with radius {c.Radius}");
break;
case Rectangle r:
Console.WriteLine($"Rectangle with width {r.Width} and height {r.Height}");
break;
}
Reference: F# Pattern Matching
F# treats functions as first-class citizens, allowing them to be passed around like any other value.
F# Example:
let add x y = x + y
C# Equivalent:
Func<int, Func<int, int>> add = x => y => x + y;
F# emphasizes immutability, which can be challenging to replicate in C#.
F# Example:
let myList = [1; 2; 3]
C# Equivalent:
List<int> myList = new List<int> { 1, 2, 3 }; // Mutable by default
F# supports computation expressions, which can be used for asynchronous programming and more.
F# Example:
let result = computation { ... }
C# Equivalent:
var result = ...; // using async/await
Reference: F# Computation Expressions
F# has powerful type inference capabilities, which can simplify code.
F# Example:
let x = 42
C# Equivalent:
int x = 42;
Active patterns in F# allow for more complex pattern matching scenarios.
F# Example:
let (|Even|Odd|) n = if n % 2 = 0 then Even n else Odd n
C# Equivalent:
bool IsEven(int n) => n % 2 == 0;
F# supports units of measure, which can help prevent errors in calculations.
F# Example:
let length: float<m> = 5.0<m>
C# Equivalent:
double length = 5.0; // no unit type
