Accessing an F# list from inside C# code

Question

I have written an F# module that has a list inside:

module MyModule
type X = 
    {
        valuex : float32
    }
let         


        

Answer 1

As simple as:

IList list = MyModule.l.ToList();

The reason you need the conversion method rather than a cast / implicit conversion is because an FSharpList implements IEnumerable but not IList since it represents an immutable linked-list.

Note that you'll have to include FSharp.Core as a reference in your C# project.
