[英]Building F# library to be used in C#
Let's say I have the following function. 假设我有以下功能。
let rec fib n =
match n with
| 1 | 2 -> 1
| n -> fib(n-1) + fib(n-2)
How can I compile this code into dll so that it's used from C#? 如何将此代码编译为dll,以便从C#中使用它?
I use both mono (in Mac OS X) and Visual Studio 2010. 我同时使用mono(在Mac OS X中)和Visual Studio 2010。
I added the following to make namespace. 我添加了以下内容来创建命名空间。
namespace MyMath.Core module public Process=
And fsc --target:library facto.fs gives me facto.dll. 和fsc --target:library facto.fs给了我facto.dll。
The C# code to use this code as follows. 使用此代码的C#代码如下。
using System;
using MyMath.Core;
class TestFSharp {
public static void Main() {
int val = MyMath.Core.Process.fib(10);
Console.WriteLine(val);
}
}
dmcs /r:facto.dll testf.cs gives me tesetf.exe. dmcs /r:facto.dll testf.cs给了我tesetf.exe。
Well, if you put this in the file Program.fs, and compile it into a library (with --target:library
), then it would appear from C# as 好吧,如果你将它放在Program.fs文件中,并将其编译成一个库 (带有
--target:library
),那么它将从C#出现
Program.fib(5)

However if you plan to expose F# code to C#, you may want to uses namespaces and types. 但是,如果您计划将F#代码公开给C#,则可能需要使用名称空间和类型。 See the F# Component Design Guidelines for more.
