JSON数组解析：如何遍历RootObject下的StoreDepartment子集合？

解决JSON子数组遍历问题

嘿，看起来你已经搞定了RootObject列表的反序列化和遍历，现在就差处理每个RootObject里的storedepartment子数组了对吧？其实方法和你遍历RootObject列表几乎一样——在现有循环里加一层嵌套的foreach循环就行，直接遍历每个RootObject实例的storedepartment集合。

下面是修改后的完整代码，我给你加上了子数组的遍历逻辑：

string sJSON = @"[{""dateNumeric"":1216000000,""hourOfDay"":0,""customerNumber"":12,""storedepartment"":[{""department"":333,""descriptionOfDepartment"":""Department A""},{""department"":111,""descriptionOfDepartment"":""Department B""}]},{""dateNumeric"":1216000000,""hourOfDay"":3,""customerNumber"":3,""storedepartment"":[{""department"":999,""descriptionOfDepartment"":""Department X""},{""department"":888,""descriptionOfDepartment"":""Department Y""}]}]";
List<RootObject> Data = JsonConvert.DeserializeObject<List<RootObject>>(sJSON);

// 遍历每个RootObject
foreach (RootObject c in Data) {
    debugOutput(c.dateNumeric.ToString());
    debugOutput(c.customerNumber.ToString());
    
    // 遍历当前RootObject下的所有Storedepartment
    foreach (Storedepartment dept in c.storedepartment) {
        debugOutput($"部门ID: {dept.department}, 部门名称: {dept.descriptionOfDepartment}");
    }
}

public class RootObject {
    public int dateNumeric { get; set; }
    public int hourOfDay { get; set; }
    public int customerNumber { get; set; }
    public List<Storedepartment> storedepartment { get; set; }
}

public class Storedepartment {
    public int department { get; set; }
    public string descriptionOfDepartment { get; set; }
}
