C# Winform反序列化复杂json字符串

2021-05-24 Windows程序

最近接的私单是一个CS项目,里面所有的操作都是通过调用API接口来进行的。

接口详细说明

协议:https  请求方式:post  
https://xx.xxx.net/app/clients

提交json 数据包

{ "action":" food_t_list", "data":{ “pageIndex”:”1”, “pageSize”:”20”, “foodGId”:”1”, “storeId”:”1” } }

返回说明
正确时返回JSON数据包:

{ "result": "1", "data": { "totalCount": "20", "pageCount": "3", “storeId”:”1”, "foodTables": [ { "foodTId": "2", "foodTName": "8号台", “foodTPeo”:”6”, “foodGrade”: {“foodGId”:”1”,”foodGName”:”大厅”}, “foodTStatus”:”1”, "foodTDesc ": "餐桌的描述", “storeId”:”1” }, { "foodTId": "5", "foodTName": "5号台", “foodTPeo”:”8”, “foodGrade”: {“foodGId”:”2”,”foodGName”:”包间”}, “foodTStatus”:”0”, "foodTDesc ": "餐桌的描述" } ] } }

错误时返回JSON数据包:

{“result”:”0”,"errcode":10036”,”errmsg":"错误信息!"} //错误代码,根据代码规则查询错误信息。

根据这个返回的json字符串,我们来构建相应的类FoodList,为后面将json反序列化为FoodList做准备

public abstract class BaseEntity
    {
       public int result { get; set; }
       public int errcode { get; set; }
       public string errmsg { get; set; }
    }

/// <summary> /// 餐桌列表 /// </summary> public class FoodList : BaseEntity { public FoodEntity data { get; set; } } public class FoodEntity { /// <summary> /// 总页数 /// </summary> public int totalCount { get; set; } /// <summary> /// 当前页数 /// </summary> public int pageCount { get; set; } /// <summary> /// 餐桌等级列表集合 /// </summary> public List<FoodTable> foodTables { get; set; } } public class FoodTable { /// <summary> /// 餐桌 ID /// </summary> public int foodTId { get; set; } /// <summary> /// 餐桌名称 /// </summary> public string foodTName { get; set; } /// <summary> /// 餐桌使用人数 /// </summary> public int foodTPeo { get; set; } /// <summary> /// 餐桌等级 /// </summary> public FoodGradeInfo foodGrade { get; set; } /// <summary> /// 餐桌状态 0 空闲 1 预定 2 使用中 /// </summary> public int? foodTStatus { get; set; } /// <summary> /// 餐桌的描述 /// </summary> public string foodTDesc { get; set; } /// <summary> /// 商铺 ID /// </summary> public int storeId { get; set; } }

那么,我需要做的,就是调用API接口,拿到json字符串,然后反序列化为对象。

C#中序列化和反序列化有多中方式,这里我采用JavaScriptSerializer,在Winform程序中使用JavaScriptSerializer需要先添加如下两个引用:

新建HttpClientUtil类,封装API请求的类,
