C# csharpcompiler 编译器程序集无法导入任何内容

Question

我一直在尝试向服务器应用程序添加命令系统
问题是:不在项目内但
的命令.cs文件它们是在运行时从另一个文件夹编译的，不能包含任何东西。

编译器代码:

static CompilerResults Compile(String path)
        {
            var csc = new CSharpCodeProvider(new Dictionary<string, string>() { { "CompilerVersion", "v3.5" } });
            var parameters = new CompilerParameters(new[] { "mscorlib.dll", "System.Core.dll" }, "DS Server.exe", true);
            parameters.GenerateExecutable = true;
            return csc.CompileAssemblyFromFile(parameters, path);
        }

外部 .cs 代码文件:

using DS_Server;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net.Sockets;
using System.Reflection;
using System.Text;
using System.Threading.Tasks;

namespace JMnet
{
    class command
    {
        public void run(TcpListener server,Dictionary<String,user> users , Dictionary<String, Assembly> Commands, String[] args)
        {
            foreach (user usr in users) {
                var IP = ((IPEndPoint)usr.getClient().Client.RemoteEndPoint).Address.ToString();
                Core.Log.Geneic("Players",IP+" is connected as "+usr.getName()+", ping: "+usr.getPing().ToString());
            }
        }
    }
}

错误:

这部分:

var parameters = new CompilerParameters(new[] { "mscorlib.dll", "System.Core.dll" }, "DS Server.exe", true);

您确实需要添加声明编译器未找到的所有类型的程序集。您只包括 mscorlib.dll 和 System.Core.dll，但您还需要包括编译后的代码需要使用的所有其他程序集。

例如，这可能是:

var parameters = new CompilerParameters(new[] { "mscorlib.dll", "System.Core.dll", "System.dll", "DS_Server.dll" }, "DS Server.exe", true);

如果您事先无法知道需要哪些程序集，请在要编译的 *.cs 文件之外放置一个配置文件，您可以在其中指定要加载的程序集列表。

另外，在这里:

var csc = new CSharpCodeProvider(new Dictionary<string, string>() { { "CompilerVersion", "v3.5" } });

您告诉编译器使用 .net Framework 3.5 版，它不包含一些较新的功能，例如 System.Threading.Tasks。添加更高的版本号，例如 4.0 或更高版本:

var csc = new CSharpCodeProvider(new Dictionary<string, string>() { { "CompilerVersion", "v4.0" } });
