C#后台处理JSON数据

json数据格式：

{"Id":20547,"Name":"中南大学","NameEn":"central-south university","AreaId":190},{"Id":20548,"Name":"湖南大学","NameEn":"Hunan university","AreaId":190},{"Id":20549,"Name":"湖南师范大学","NameEn":"hunan normal university","AreaId":190}

 

首先还是介绍下实体类吧，在这切记类名和json的大小写什么的都要一致。

        public class School
        {
            [System.Runtime.Serialization.DataMember]
            public string Id { get; set; }
            [System.Runtime.Serialization.DataMember]
            public string Name { get; set; }
            [System.Runtime.Serialization.DataMember]
            public string NameEn { get; set; }
            [System.Runtime.Serialization.DataMember]
            public string AreaId { get; set; }
        }

 

获取单单一条结果集我参考了下别人的写法：
        public static School getOneJson(string jsonText)
        {
            using (MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(jsonText)))
            {
                DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(School));
                return (School)serializer.ReadObject(ms);
            }

        }
