无法在CSharpCodeProvider脚本中包含Newtonsoft JSON [英] Can't include Newtonsoft JSON in CSharpCodeProvider script

问题描述

我正在尝试在动态编译的脚本中使用JSON.但是，当我包含该库并添加JObject时，会出现类似以下错误:在未引用的程序集中定义了类型'System.Dynamic.IDynamicMetaObjectProvider'.您必须添加对程序集'System.Core，Version = 4.0.0.0，Culture = neutral，PublicKeyToken = b77a5c561934e089'的引用."

I am trying to use JSON in a dynamically compiled script. However, when I include the library and add a JObject, I get errors like: "The type 'System.Dynamic.IDynamicMetaObjectProvider' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Core, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'."

我包括MathNet.数值很好.

I included MathNet.Numerics just fine.

这是我的设置.

• 控制台应用程序.NET Framework 4(因此它与运行时匹配 编译)
• Nuget安装MathNet.Numerics
• Nuget安装Newtonsoft
• 将运行时编译文件与dll指向调试文件夹.

• Console application .NET Framework 4 (so it matches the runtime compile)
• Nuget install MathNet.Numerics
• Nuget install Newtonsoft
• Point the runtime compile to the debug folder with the dlls.

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();
    }
  }
}

推荐答案

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

You need add a reference to System and System.Core from the GAC (Global Assembly Cache) :

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

我认为这取决于 Newtonsoft.Json .
