确认属性名和json字段名都匹配，并标注好对应的属性类型。例如： public class Person { public string Name { get; set; } [JsonProperty("age")] //指定json中字段名 public int Age { get; set; } }

在序列化和反序列化时使用NewtonJson的序列化器和反序列化器，并配置好选项。例如： var options = new JsonSerializerOptions { PropertyNamingPolicy = JsonNamingPolicy.CamelCase, //将属性名转为小驼峰式 WriteIndented = true //格式化输出json }; //序列化 var jsonString = JsonSerializer.Serialize(person, options); //反序列化 var person = JsonSerializer.Deserialize(jsonString, options);

如果仍然无法映射，则可以尝试自定义解析器。例如： public class CustomJsonConverter : JsonConverter { public override bool CanConvert(Type typeToConvert) => typeToConvert == typeof(Person);

 public override Person Read(ref Utf8JsonReader reader, Type typeToConvert, JsonSerializerOptions options)
 {
     var obj = JsonSerializer.Deserialize(ref reader); //解析json元素
     var name = obj.GetProperty("name").GetString(); //获取属性值并转换为Person对象
     var age = obj.GetProperty("age").GetInt32();
     return new Person { Name = name, Age = age };
 }

 public override void Write(Utf8JsonWriter writer, Person value, JsonSerializerOptions options)
 {
     writer.WriteStartObject();
     writer.WriteString("name", value.Name);
     writer.WriteNumber("age", value.Age);
     writer.WriteEndObject();
 }

} //序列化 var jsonString = JsonSerializer.Serialize(person, typeof(Person), new JsonSerializerOptions { Converters = { new CustomJsonConverter() } //添加自定义解析器 }); //反序列化 var person = JsonSerializer.Deserialize(jsonString, new JsonSerializerOptions { Converters = { new CustomJsonConverter
