CompileAssemblyFromFile

问题

Why I get the error when trying to do this function:

   let compile_file path use_asms output =
    use pro = new FSharpCodeProvider()
    let opt = CompilerParameters(use_asms, output)
    let res = pro.CompileAssemblyFromFile(opt, path) // <-- Error
    if res.Errors.Count = 0 
    then Some(FileInfo(res.PathToAssembly))
    else None 

Error-code: -2147467259

Error: cant find the file specified

Now I'm trying two broken implementations:

type System.CodeDom.Compiler.ICodeCompiler with 
    member this.CompileAssemblyFromFile 
            (options:CompilerParameters,fileName:string) : CompilerResults = 
        this.CompileAssemblyFromFileBatch(options, [|fileName|])

let compile_file str assemblies output =
    let pro = new System.CodeDom.Compiler.CodeCompiler()
    let opt = CompilerParameters(assemblies, output)
    let res = pro.CompileAssemblyFromFile(opt, str)
    if res.Errors.Count = 0 then 
         Some(FileInfo(res.PathToAssembly)) 
    else None

let compile_file2 path use_asms output =
    use pro = new FSharpCodeProvider()
    let opt = CompilerParameters(use_asms, output)
    let res = pro.CompileAssemblyFromFile(opt, path)
    if res.Errors.Count = 0 
    then Some(FileInfo(res.PathToAssembly))
    else None
