How to Convert FSharpList back to List in c#?

问题

I have an F# library that returns an FSharpList to my C# caller.

I would now like my C# caller's code to convert this into a List.

What is the most efficient way to do this in C#?

Thanks.

回答1:

Easier than I thouglt...

Starting with:

List<double> niceList= new List<double>();

From List to FSharpList I did this:

FSharpList<double> niceSharpList = ListModule.OfSeq(niceList);

and to convert back from FSharpList to List I did:

List<double> niceList= niceSharpList.ToList();

To make this work it is essential to add references to the project core F # 4.0

For example in F# you have this

/// A list with 3 integers
let listA = [ 1; 2; 3 ]     

you can use in C# in very simply way

List<Int32> listCSHARP = Module1.listA.ToList();

foreach (Int32 i in listCSHARP)
{
     MessageBox.Show(i.ToString());
}
