c# - 从 C# 执行 F# 源代码

Question

我想找到一个使用 C# 编译 F# 代码的 CompileAssemblyFromSource 的工作示例。在我目前的尝试中，我无法创建编译器，出现“NotSupportedException”异常，“不支持编译”消息。我的猜测是我只是做错了，因为 F# Interactive 可以工作并且必须做类似但正确的事情。

// C#
var source = "let add x y = x + y";
var cleanProvider = new FSharp.Compiler.CodeDom.FSharpCleanCodeProvider();
var compilerParams = new System.CodeDom.Compiler.CompilerParameters();
const string outfile = "C:\\temp\\FSFoo.EXE";
compilerParams.OutputAssembly = outfile;
compilerParams.GenerateExecutable = true;

var compiler = cleanProvider.CreateCompiler();
var compilerResults = compiler.CompileAssemblyFromSource(compilerParams, source);
var results = cleanProvider.CompileAssemblyFromSource(compilerParams, source);

仅此代码就可以编译您想要的内容，还有额外的诊断/调试代码。

using FSharp.Compiler.CodeDom;
using System.CodeDom;
var codeString = "let add x y = x + y";
var provider = new FSharp.Compiler.CodeDom.FSharpCodeProvider();
Environment.CurrentDirectory.Dump("exe is going here"); // diagnostic helper
var targetFile = "FSFoo.exe";
provider .CompileAssemblyFromSource( new System.CodeDom.Compiler.CompilerParameters(){ OutputAssembly= targetFile, GenerateExecutable=true }, new []{codeString}).Dump(); // .Dump is just for diagnostics, remove if you aren't running this in linqpad
if(!System.IO.File.Exists(targetFile)){
    throw new FileNotFoundException("Could not find compiled exe",targetFile);
}

System.IO.Directory.GetFiles(Environment.CurrentDirectory,"FSFoo.exe").Dump();// .Dump is just for diagnostics, remove if you aren't running this in linqpad
