DataContractJsonSerializer:令牌“null”是预期的，但发现“new ”
本文关键字：new 发现 令牌 null DataContractJsonSerializer | 更新日期: 2023-09-27 18:32:02
当我尝试将JSON反序列化为对象时收到此错误。
Additional information:
There was an error deserializing the object of type uwpPlatenInformationScreen.Models.RootObject. The token 'null' was expected but found 'new '.
找不到任何解决方案，我将其设置为 UTF8，并且我有一个正确的 JSON 模型。
我的根对象没有错，所以我不知道该考虑什么了。
功能：
public static async Task<RootObject> GetTodaysLunch(ObservableCollection<RootObject> menu )
{
string jsonMessage = await GetJsonDataFromMashie();
//deserialize json data into object
var serializer = new DataContractJsonSerializer(typeof (RootObject));
var ms = new MemoryStream(Encoding.UTF8.GetBytes(jsonMessage));
RootObject result = (RootObject) serializer.ReadObject(ms);
return result;
}
JSON 字符串（API 格式不佳）：

问题如下："new Date（12345）"
不能被Microsoft的 JSON 反序列化程序协调，但是"/Date（12345）/"是！
通过使用正则表达式，我能够使用以下代码替换和修复我的 JSON 字符串，然后再将其转换为对象：
private static string FixDataTimeJsonData(string jsonMessage)
{
string tempFixed = Regex.Replace(jsonMessage, @"new Date[(]", @"""'/Date(");
tempFixed = Regex.Replace(tempFixed, @"d*([)])", @")'/""");
return tempFixed;
}
您的 RootObject 应如下所示。
public class DayMenu
{
public string PortionTypeId { get; set; }
public bool HasExtendedInfo { get; set; }
public object MealPictureURL { get; set; }
public string MenuAlternativeName { get; set; }
public string DayMenuInfo { get; set; }
public string DayMenuName { get; set; }
public string MealId { get; set; }
public bool ShowDayNutrient { get; set; }
public bool ShowWeekNutrient { get; set; }
public bool ShowIngredients { get; set; }
}
public class Day
{
public object InfoText { get; set; }
public object DayMenuDate { get; set; }
public List<DayMenu> DayMenus { get; set; }
}
public class Week
{
public string MenuId { get; set; }
public string MenuName { get; set; }
public int WeekNumber { get; set; }
public List<Day> Days { get; set; }
}
public class RootObject
{
public List<Week> Weeks { get; set; }
public string PortionTypeId { get; set; }
public int CurrentWeek { get; set; }
public object MenuPresInfoText { get; set; }
public string MenuId { get; set; }
}
此对象将成功反序列化。如果您收到此类错误，您可以随时使用本网站 http://json2csharp.com/来验证您的对象。由于空值，那里说"对象"。如果您知道可能的值，则可以将它们更改为字符串或适当的其他类型，但 DayMenuDate 最好是"对象"类型，以便成功反序列化。
