问题 将文本字符串解析为F＃-code

可以使用实现所需的 F＃CodeDom提供商。下面的最小可运行代码段演示了所需的步骤。它从字符串中获取一个任意大概正确的F＃代码，并尝试将其编译为汇编文件。如果成功，那么它从中加载这个刚刚合成的组件 dll 从那里调用并调用一个已知函数，否则它会显示编译代码的问题。

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"

被激发它会产生预期的输出

Success: "I've been compiled on the fly!"

如果您要使用片段，则需要参考 FSharp.Compiler.dll 和 FSharp.Compiler.CodeDom.dll。请享用！
