无法在C＃中解析BinaryFormatter的程序集

Question

我正在尝试序列化一个结构，并能够在以后对其进行反序列化。使用stackoverflow上的上一篇文章，我在以下代码中实现了this article中显示的方法...

using Neo.SmartContract.Framework;
using Neo.SmartContract.Framework.Services.Neo;
using System;
using System.Numerics;
using System.IO;
using System.Runtime.Serialization.Formatters.Binary;


namespace tcardebug
{
    public class Contract1 : SmartContract
    {
        public static void Main(params object[] args)
        {
            Driver driver = (Driver)args[0];
            string license = (string)args[1];
            AddDriver(driver.first, driver.last, license);
            Runtime.Notify("Driver Added", driver, license);
        }

        [Serializable]
        public struct Driver
        {
            public string first;
            public string last;
            //public string license;

            public Driver(string _first, string _last)
            {
                first = _first;
                last = _last;
                // license = _license;
            }
        }

        private static byte[] ObjectToByteArray(Object obj)
        {
            if (obj == null)
                return null;

            BinaryFormatter bf = new BinaryFormatter();
            using (MemoryStream ms = new MemoryStream())
            {
                bf.Serialize(ms, obj);

                return ms.ToArray();
            }

        }

        private static T ByteArrayToObject<T>(byte[] arrBytes)
        {
            MemoryStream memStream = new MemoryStream();
            BinaryFormatter binForm = new BinaryFormatter();
            memStream.Write(arrBytes, 0, arrBytes.Length);
            memStream.Seek(0, SeekOrigin.Begin);
            T obj = (T)binForm.Deserialize(memStream);
            return obj;
        }

        public static bool AddDriver(string first, string last, string license)
        {

            Driver driver = new Driver(first, last);

            //byte[] keyBytes = Encoding.ASCII.GetBytes(license);
            byte[] valueBytes = ObjectToByteArray(driver);
            Storage.Put(Storage.CurrentContext, license, valueBytes);

            return true;
        }
    }

    }

这给了我以下错误......

以前，我忘记了[Serializable]在我的结构上面，但添加这个没有帮助。我有什么步骤吗？
