json序列化大小写问题

JsonProperty属性解决

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

使用newtonsoft.json来设置格式化的方式（推荐使用）

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);
