不能在 CSharpCodeProvider 脚本中包含 Newtonsoft JSON

Question

我正在尝试在动态编译的脚本中使用 JSON。但是，当我包含库并添加 JObject 时，出现如下错误：“类型 'System.Dynamic.IDynamicMetaObjectProvider' 是在未引用的程序集中定义的。您必须添加对程序集 'System.Core, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' 的引用”。 =12=]

我包括了MathNet.Numerics就好了。

这是我的设置。

控制台应用程序 .NET Framework 4（所以它匹配运行时编译)
Nuget 安装MathNet.Numerics
Nuget 安装 Newtonsoft
将运行时编译指向带有 dll 的调试文件夹。

测试代码

using System;
using System.IO;
using System.Collections.Generic;
using Newtonsoft.Json.Linq;
using Newtonsoft.Json;
using Microsoft.CSharp;
using System.Reflection;
using System.CodeDom.Compiler;

namespace ConsoleApp1
{

  public class RunScript0
  {


    public bool Compile()
    {

      //Add using statements here
      string source = "namespace UserScript\r\n{\r\nusing System;\r\n" +
                "using System.IO;\r\n" +
                "using System.Collections.Generic;\r\n" +
                "using MathNet.Numerics.Distributions;\r\n" +
                "using Newtonsoft.Json.Linq;\r\n" +
                "using Newtonsoft.Json;\r\n" +
                "public class RunScript\r\n{\r\n" +
                "private const int x = 99;\r\n" +
                "public int Eval()\r\n{\r\n" +
                //Remove following line and all works fine
                "JObject j = new JObject();\r\n" +
                "return x; \r\n\r\n}\r\n}\r\n}";

      Dictionary<string, string> provOptions =
        new Dictionary<string, string>();

      provOptions.Add("CompilerVersion", "v4.0");
      CodeDomProvider compiler = new CSharpCodeProvider(provOptions);


      CompilerParameters parameters = new CompilerParameters();
      string appPath = System.IO.Directory.GetCurrentDirectory();
      parameters.ReferencedAssemblies.Add(appPath + "\MathNet.Numerics.dll");
      parameters.ReferencedAssemblies.Add(appPath + "\Newtonsoft.Json.dll");
      //Tried adding but didn't help parameters.ReferencedAssemblies.Add(appPath + "\System.Core.dll");

      parameters.GenerateInMemory = true;
      var results = compiler.CompileAssemblyFromSource(parameters, source);
      // Check for compile errors / warnings
      if (results.Errors.HasErrors || results.Errors.HasWarnings)
      {
        Console.WriteLine(results.Errors.Count.ToString() + " Erorrs");
        for (int i = 0; i < results.Errors.Count; i++)
          Console.WriteLine(results.Errors[i].ToString());
        return false;
      }
      else
      {
        Console.WriteLine("Compiled Successfully");
        return true;
      }
    }
  }
  class Program
  {
    static void Main(string[] args)
    {
      RunScript0 A = new RunScript0();
      A.Compile();
    }
  }
}

您需要从 GAC（全局程序集缓存）添加对 System 和 System.Core 的引用：

parameters.ReferencedAssemblies.Add("System.dll");
parameters.ReferencedAssemblies.Add("System.Core.dll");

我认为它依赖于 Newtonsoft.Json.
