反序列化 RestClient 响应枚举转换错误 - 无法将 JSON 值转换为枚举

问：

在我们的 asp.net 应用程序中，我们最近从 restsharp 106.12.0 升级到 110.2.0。 旧版本没有问题，但是在升级后对代码进行了很少的更改，我们收到了错误：

无法将 JSON 值转换为 SubExCore.Models.Enums.YearType. 路径：$.body。年份类型 |行号：0 |BytePositionInLine：

无法将 JSON 值转换为 System.Nullable'1[SubExCore.Models.Enums.SectionType]。路径： $.body.sectionType |行号：0 |BytePositionInLine

这是我通过反序列化 json 响应响应来获取 YearBook 响应的 api 方法。

        public YearBook GetYearBook()
        {
            RestRequest request = new RestRequest(MethodType)
            {
                RequestFormat = DataFormat.Json,
                Resource = ApiPath,
                Method = Method.GET,
                JsonSerializer = new CustomJsonSerializer()
            };
            RestRequest request = new RestRequest() { RequestFormat = DataFormat.Json, Resource = ApiPath, Method = Method.Get };
            var options = new RestClientOptions()
            {
                BaseUrl = new Uri(BaseAddress),
                CachePolicy = new System.Net.Http.Headers.CacheControlHeaderValue() { NoCache = true, NoStore = true }
            };
            RestClient client = new RestClient(options);
            if (!Token.IsNullOrWhiteSpace())
            {
                client.AddDefaultHeader("Authorization", "authToken " + Token);
            }
            client.AddDefaultHeader("Cache-Control", "no-cache");
            var myresonse = client.Execute<YearBook>(request);
            return myresonse.Data;
        }

这是我的 YearBook 类，带有 Enum 属性

[Table(TableName = "tblYearBook")]
public class YearBook
{
    [Map(ColumnName = "year_id"), Key]
    public int Year { get; set; }

    [Map(ColumnName = "year_type")]
    public YearType YearType { get; set; }

    [Map(ColumnName = "section_type")]
    public SectionType? Section { get; set; }

    [Map(ColumnName = "college_name")]
    public string CollegeName { get; set; }

    [Map(ColumnName = "avg_pass")]
    public decimal AvgPass { get; set; }
}

public enum YearType
{
    FirstYear,
    SecondYear,
    ThirdYear
}

public enum SectionType
{
     None,
     MIT,
     BIT
}

这是我从该方法获得的 json 响应。

{
    "year_id": "2005",
    "year_type": "FirstYear",
    "section_type": "None",
    "college_name": "St. Alphores Govt College",
    "avg_pass" : 89
}

前面，我们已经在 RestSharp.Serializers.ISerializer 中实现了 CustomSerializer。新的 Restsharp 版本现在实现了 IRestSerializer 中的 customserializer。互联网上的 Restsharp 文档 neight 中没有足够的细节。 谁能给我一个正确的IRestSerializer实现，它具有以下序列化设置。

这是我现有的带有 Restsharp 版本 106.12.0 的自定义序列化程序类

public class CustomJsonSerializer : RestSharp.Serializers.ISerializer
    {
        public CustomJsonSerializer()
        {
            var restSerializer = new RestSharp.Serialization.Json.JsonSerializer();
            this.ContentType = restSerializer.ContentType;
        }
        public string ContentType { get; set; }
        public string DateFormat { get; set; }
        public string Namespace { get; set; }
        public string RootElement { get; set; }
        private JsonSerializerSettings SerializerSettings
        {
            get
            {
                JsonSerializerSettings settings = new JsonSerializerSettings();
                settings.Converters.Add(new StringEnumConverter());
                settings.Converters.Add(new DateTimeJsonConverter());
                settings.DateTimeZoneHandling = DateTimeZoneHandling.Utc;
                settings.ContractResolver = new CamelCasePropertyNamesContractResolver();
                return settings;
            }
        }
        string RestSharp.Serializers.ISerializer.Serialize(object obj)
        {
            return Newtonsoft.Json.JsonConvert.SerializeObject(obj, SerializerSettings);
        }
    }
