Question

c#怎么返回一个json数据类型

Answer 1

使用newtonsoft.json.dll
public static string ObjectToJson(object obj)
{
JsonSerializerSettings setting = new JsonSerializerSettings();
setting.CheckAdditionalContent = false;
setting.NullValueHandling = NullValueHandling.Ignore;
setting.ObjectCreationHandling = ObjectCreationHandling.Reuse;
string jsonString = JsonConvert.SerializeObject(obj, Formatting.None, setting);
return jsonString;
}
可以返回一个json字符串
