如何自定义C# deserializeobject

在C#中，可以使用Json.NET库来自定义反序列化对象。下面是一个简单的例子：

using Newtonsoft.Json;  public class Person {     public string Name { get; set; }     public int Age { get; set; } }  public class CustomDeserializer : JsonConverter {     public override bool CanConvert(Type objectType)     {         return objectType == typeof(Person);     }      public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)     {         JObject jObject = JObject.Load(reader);          Person person = new Person();         person.Name = jObject.GetValue("name").ToString();         person.Age = jObject.GetValue("age").Value<int>();          return person;     }      public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)     {         throw new NotImplementedException();     } }  class Program {     static void Main()     {         string json = "{\"name\":\"John\",\"age\":30}";          JsonSerializerSettings settings = new JsonSerializerSettings();         settings.Converters.Add(new CustomDeserializer());          Person person = JsonConvert.DeserializeObject<Person>(json, settings);          Console.WriteLine($"Name: {person.Name}, Age: {person.Age}");     } } 

在上面的例子中，我们定义了一个自定义的JsonConverter类CustomDeserializer，用于反序列化Person对象。在ReadJson方法中，我们手动提取json中的数据并创建一个Person对象。然后将这个CustomDeserializer类添加到JsonSerializerSettings中，并传递给JsonConvert.DeserializeObject方法来实现自定义反序列化。
