Question

First part: call F# from F#

Let’s say we have the following type defined in F#:

type MyClass =
    static member Overload1 (x, y) = "Pim"
    static member Overload1 (x : System.Tuple<_, _>) = "Pam"
    static member Overload1 x = "Pum"

You are now in another module (in another file).

How can you call each of the three methods shown above?

Second part: call C# from F#

Now, you define a class in C#:

public class MyClass {
    public static string Overload1<a, b>(a x, b y) { return "Pim"; }
    public static string Overload1<a, b>(Tuple<a, b> x) { return "Pam"; }
    public static string Overload1<a>(a x) { return "Pum"; }
}

From a F# code, how can you call each of the three methods now defined in C#?

Answer 1

Here’s an answer to the F# part:

MyClass.Overload1(1,2)
MyClass.Overload1<_,_>(unbox (box (1,2)) : System.Tuple<int,int>)
MyClass.Overload1 1
