我正在尝试使用基本程序来动态编译和运行f#代码。我正在尝试运行以下代码:
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"
我遇到的问题是以下一行:
let result = provider.CompileAssemblyFromSource( options, [|codeString|] )
我获得例外的地方:The System cannot find the file specified.
我已经包含了必需的引用Fsharp.compiler.codeDom.dll
和Fsharp.compiler.dll
,我不确定还有什么问题。我目前正在尝试从{code}获取CodeDom
的dll源代码并逐步完成它,但如果有人能够看到我忽略的一些问题,那将会让我感到很头疼。
感谢您的时间, -Alper

在F#PowerPack下面,CodeDOM实现使用F#编译器生成代码,这意味着它需要一种方法来查找编译器和相关的元数据。
首先,您可能需要将FSharp.Core.sigdata文件复制到bin文件夹(元数据)。您可能还需要将F#编译器(fsc.exe)添加到路径中,或者只是将其复制到bin文件夹中(fsc.exe位于C:\ Program Files(x86)\ Microsoft SDKs \ F#\ 3.0 \ Framework \ V4.0)。在安装了Visual Studio 2012的Windows 8计算机上,Atleast这对我有用。
