系统.typeeloadeexception:当使用MessagePack时，访问被拒绝

我试图使用MessagePack来序列化我的对象，但是每当我试图运行序列化时，我都会得到一个未处理的异常错误。

下面是我的代码:

CSCDP_TCPClient.cs

using System.Text;
using System.Threading.Tasks;
using System.Net.Sockets;
using System.Diagnostics;
using System.IO;
using MsgPack;
using MsgPack.Serialization;
namespace CSCDPApp
{
    class CSCDP_TCPClient
    {
        public void Connect(string server, int portno, Script Script)  
        {
            var serializer = MessagePackSerializer.Get<Script>();
            var tempstream = new MemoryStream();
            serializer.Pack(tempstream, script);
            tempstream.Position = 0;
            var deserializedObject = serializer.Unpack(tempstream);
            Debug.WriteLine("Same object? {0}", Object.ReferenceEquals(script, deserializedObject));
        }
    }
}

Script.cs:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace CSCDPApp
{
    class Script
    {
        public string cardID;
        public string time;
        public string device;
        public string command;
        public Script()
        {
            //Parameterless Constructor for serialization
        }
        public Script(string cardID, string time, string device, string command)
        {
            this.cardID = cardID;
            this.time = time;
            this.device = device;
            this.command = command;
        } 
    }
}

我只是在main中使用:

        CSCDP_TCPClient tcpclient = new CSCDP_TCPClient();
        Script tempscript = new Script("test1","test2","test3","test4");
        tcpclient.Connect("0.0.0.0",1,tempscript);

这里是我得到的错误:

我在我的D:驱动器中有我的visual studio项目，并且我已经检查了权限是否正确。我将MessagePack.dll与所有已编译的可执行文件放在同一目录中，并链接了引用。有什么我可能遗漏的吗?
