C#实体对象序列化成Json并让字段的首字母小写的两种解决方法

public class UserInfo{  [JsonProperty("id")]  public int Id{ set; get; }  [JsonProperty("userName")]  public string UserName{ set; get; }}

var user = new { Name = "john", Age = 19 };  var serializerSettings = new JsonSerializerSettings      {        // 设置为驼峰命名        ContractResolver = new CamelCasePropertyNamesContractResolver()      };var userStr = JsonConvert.SerializeObject(user, Formatting.None, serializerSettings);
