我正在尝试使用一个基本程序来动态编译和运行f#代码。我试图运行以下代码:
open System
open System.CodeDom.Compiler
open Microsoft.FSharp.Compiler.CodeDom
// Our (very simple) code string consisting of just one function: unit -> string
let codeString =
"module Synthetic.Code\n let syntheticFunction() = \"I've been compiled on the fly!\""
// Assembly path to keep compiled code
let synthAssemblyPath = "synthetic.dll"
let CompileFSharpCode(codeString, synthAssemblyPath) =
use provider = new FSharpCodeProvider()
let options = CompilerParameters([||], synthAssemblyPath)
let result = provider.CompileAssemblyFromSource( options, [|codeString|] )
// If we missed anything, let compiler show us what's the problem
if result.Errors.Count <> 0 then
for i = 0 to result.Errors.Count - 1 do
printfn "%A" (result.Errors.Item(i).ErrorText)
result.Errors.Count = 0
if CompileFSharpCode(codeString, synthAssemblyPath) then
let synthAssembly = Reflection.Assembly.LoadFrom(synthAssemblyPath)
let synthMethod = synthAssembly.GetType("Synthetic.Code").GetMethod("syntheticFunction")
printfn "Success: %A" (synthMethod.Invoke(null, null))
else
failwith "Compilation failed"来自本网站:http://infsharpmajor.wordpress.com/2012/04/01/how-to-dynamically-synthesize-executable-f-code-from-text/
我面临的问题是以下几点:
let result = provider.CompileAssemblyFromSource( options, [|codeString|] ) 在这里我得到了例外:The System cannot find the file specified.
我已经包含了所需的参考资料Fsharp.compiler.codeDom.dll和Fsharp.compiler.dll,我不知道还会有什么问题。我目前正在尝试从codeplex中获取CodeDom的dll源代码,并逐步完成它,但是如果有人能够看到我忽略的一些问题,它会让我省去很多麻烦。
谢谢你抽出时间,-Alper

在F# PowerPack的CodeDOM实现下,使用F#编译器生成代码,这意味着它需要找到编译器和相关元数据的方法。
首先,您可能需要将FSharp.Core.sigdata文件复制到bin文件夹(元数据)。您还可能需要将F#编译器(fsc.exe)添加到路径中,或者只需将其复制到bin文件夹中(fsc.exe位于C:\Program (x86)\Microsoft SDKs\F#\3.0\Framework\v4.0中)。至少在我安装了Visual 2012的Windows 8计算机上,这是可行的。
