本文实例讲述了C#实现JSON和对象之间互相转换功能。分享给大家供大家参考，具体如下：
1.首先是声明用户信息对象，DataContract修饰类，表示可以被解析成JSON，DataMember修饰属性，Order表示 解析的顺序，另外Lover是数组列表，表示女朋友个数
Address 表示送货地址，DailyRecord 表示日常记录

//1.对象-->JSONUserInfo info = new UserInfo{ Age = 10, Gender = 1, UserName = "刘德华", Lover = new List<string> { "美女1", "美女2", "美女3" }, Address = new ContactAddress { Province = "湖南省", City = "长沙市", Country = "望城县", Details = "某旮旯快递找不到的地方" }, DailyRecord = new Dictionary<string, string> { { "星期一", "吃饭" }, { "星期二", "洗衣服" }, { "星期三", "好事情" } }};string json = ObjectToJSON<UserInfo>(info); |
4.反序列化后的结果
复制代码 代码如下:
{"UserName":"刘德华","Age":10,"Gender":1,"Lover":["美女1","美女2","美女3"],"Address":{"Province":"湖南省","City":"长沙市","Country":"望城县","Details":"某旮旯快递找不到的地方"},"DailyRecord":[{"Key":"星期一","Value":"吃饭"},{"Key":"星期二","Value":"洗衣服"},{"Key":"星期三","Value":"好事情"}]}
希望本文所述对大家C#程序设计有所帮助。
