c# - 将 Json 字符串转换为 C# 对象无效

Question

我想将此 Json 字符串转换为 C# 对象，我尝试从一些教程中学习但没有用，我正在尝试转换此 json 字符串:

 string myJson = "{\"response\": {\"status\": {\"code\": 1002,\"label\": \"UPLOAD_SUCCESS\",\"message\": \"The file was uploaded successfully.\"},\"md5\": \"da855ff838250a05692f14e\",\"file_name\": \"MyFile.docx\",\"file_type\": \"docx\",\"features\": [ \"te\" ],\"te\": {\"images\": [{\"report\": {\"verdict\": \"unknown\"},\"status\": \"not_found\",\"id\": \"5e5de275-a103-4f67-b532918fa59\",\"revision\": 1},{\"report\": {\"verdict\": \"unknown\"},\"status\": \"not_found\",\"id\": \"7e6fe36e-889e-4c25-8704-5637830df\",\"revision\": 1}],\"status\": {\"code\": 1001,\"label\": \"FOUND\",\"message\": \"The requested data has been found.\"}}}}";

我创建了这个类:

 public partial class Welcome
    {
        [JsonProperty("response")]
        public Response response { get; set; }
    }

    public partial class Response
    {
        [JsonProperty("status")]
        public Status status { get; set; }

        [JsonProperty("md5")]
        public string md5 { get; set; }

        [JsonProperty("file_name")]
        public string fileName { get; set; }

        [JsonProperty("file_type")]
        public string file_type { get; set; }

        [JsonProperty("features")]
        public string[] features { get; set; }

        [JsonProperty("te")]
        public Te te { get; set; }
    }

    public partial class Status
    {
        [JsonProperty("code")]
        public long code { get; set; }

        [JsonProperty("label")]
        public string label { get; set; }

        [JsonProperty("message")]
        public string message { get; set; }
    }

    public partial class Te
    {
        [JsonProperty("images")]
        public Image[] images { get; set; }

        [JsonProperty("status")]
        public Status status { get; set; }
    }

    public partial class Image
    {
        [JsonProperty("report")]
        public Report report { get; set; }

        [JsonProperty("status")]
        public string status { get; set; }

        [JsonProperty("id")]
        public string Id { get; set; }

        [JsonProperty("revision")]
        public long Revision { get; set; }
    }

    public partial class Report
    {
        [JsonProperty("verdict")]
        public string verdict { get; set; }
    }

    public partial class Welcome
    {
        public static Welcome FromJson(string json) => JsonConvert.DeserializeObject<Welcome>(json, Converter.Settings);
    }

    public static class Serialize
    {
        public static string ToJson(this Welcome self) => JsonConvert.SerializeObject(self, Converter.Settings);
    }

    public class Converter
    {
        public static readonly JsonSerializerSettings Settings = new JsonSerializerSettings
        {
            MetadataPropertyHandling = MetadataPropertyHandling.Ignore,
            DateParseHandling = DateParseHandling.None,
        };
    }

最后我尝试访问对象的值:

    Welcome result = new System.Web.Script.Serialization.JavaScriptSerializer().Deserialize<Welcome>(json);
                Console.WriteLine(result);  

你能告诉我如何将这个 Json 字符串转换为 C# 对象吗？我找了很多教程，但有一段时间没有成功，所以也许你可以帮我节省一些时间。

Answer 1

你应该使用

Welcome result = JsonConvert.DeserializeObject<Welcome>(myJson);

然后你可以很容易地通过使用访问它

Console.WriteLine(result.response.status.code);
