Newtonsoft.Json反序列化失败

Question

重构一个类之后，用

file.Write(JsonConvert.SerializeObject(this, Formatting.Indented));

按照预期工作，并生成本期中描述的json文件。但是，反序列化不再有效。

http://json2csharp.com能够正确地检索对象结构。

源/目标类型

 public class VinciModel
    {
        public string Name { get; set; }
        public string VidiWorkspaceDir { get; set; }
        public string ViDiWorkspaceName { get; set; }

        public int NRows { get; set; }
        public List<List<object>> Rows { get; set; }
        public int NChocolates { get; set; }
        public List<StreamInfo> StreamList { get; set; }
        public float BlisterWidth { get; set; }
        public float BlisterHeight { get; set; }
    }

    public class Socket
    {
        public int Index { get; set; }
        public string StreamName { get; set; }
        public Rectangle ROI { get; set; }
    }

    public class StreamInfo
    {
        public string StreamName { get; set; }
        public List<Socket> Sockets { get; set; } = new List<Socket>();
    }
}

错误

Newtonsoft.Json.JsonReaderException：‘分析值时遇到意外字符：{。路径’行‘，第8行，位置7。’

重现步骤

using (var file = new System.IO.StreamReader(path))
    JsonConvert.DeserializeObject<VinciModel>(file.ReadToEnd());

在类被重构之前工作

我也试过了：

var obj = JsonConvert.DeserializeObject<JObject>(file.ReadToEnd());

并得到：“读取字符串时出错。意外的标记: StartObject。路径为‘Rows’。”

Answer 1

问题是我的类有一个非默认构造函数，没有默认构造函数。错误消息无关紧要。
