使用Newtonsoft.Json.dll 序列化为json时主动将NULL值过滤掉。详细做法:
var jSetting = new JsonSerializerSettings {NullValueHandling = NullValueHandling.Ignore}; var json = JsonConvert.SerializeObject(response, Formatting.Indented, jSetting);
之前转换的JSON为:
{"header":{"responseCode":"200","responseDesc"":"运行成功","responseDescErrorMsg":""。"responseDescTime":"2015-07-07T13:40:48.7162196+08:00"}。"body":{"order":{"orderid":"S1507070001"},"product":null}}
參加代码后转换出来的为:
{"header":{"responseCode":"200","responseDesc":"运行成功","responseDescErrorMsg":""。"responseDescTime":"2015-07-07T13:40:48.7162196+08:00"},"body":{"order":{"orderid":"S1507070001"}}}
