将JSON反序列化为C#对象-未反序列化任何数据

尝试将JSON字符串反序列化为C#对象时发现一个奇怪的问题。它“似乎”成功地执行了操作（因为它不会引发任何异常等），但是输出的POCO不包含JSON字符串中的任何数据，它只包含类型默认数据（null、“、0等）。我用其他JSON尝试过这个过程，效果很好

    private string GetJson()
    {
        return @"{""backdrop_path"":"" / 1LrtAhWPSEetJLjblXvnaYtl7eA.jpg"",""created_by"":[{""id"":488,""name"":""Steven Spielberg"",""profile_path"":"" / pOK15UNaw75Bzj7BQO1ulehbPPm.jpg""},{""id"":31,""name"":""Tom Hanks"",""profile_path"":"" / a14CNByTYALAPSGlwlmfHILpEIW.jpg""}],""episode_run_time"":[60],""first_air_date"":""2001 - 09 - 09"",""genres"":[{""id"":28,""name"":""Action""},{""id"":12,""name"":""Adventure""},{""id"":18,""name"":""Drama""},{""id"":10752,""name"":""War""}],""homepage"":""http://www.hbo.com/band-of-brothers"",""id"":4613,""in_production"":false,""languages"":[""de"",""fr"",""lt"",""nl"",""en""],""last_air_date"":""2001-11-04"",""name"":""Band of Brothers"",""networks"":[{""id"":49,""name"":""HBO""}],""number_of_episodes"":10,""number_of_seasons"":1,""origin_country"":[""GB"",""US""],""original_language"":""en"",""original_name"":""Band of Brothers"",""overview"":""Drawn from interviews with survivors of Easy Company, as well as their journals and letters, Band of Brothers chronicles the experiences of these men from paratrooper training in Georgia through the end of the war.

任何想法-我肯定我错过了一些显而易见的东西，但我看不到。使用.NET4.5

谢谢你的帮助

干杯

我用过，代码是这样的，所以你应该看看

您可以在VS-IDE中使用粘贴特殊功能

粘贴JSON作为类

}

    public object score { get; set; }

看起来您的JSON字符串的格式不正确，您正在尝试反序列化。例如，我在C#类中没有找到

show

属性，但它以JSON的形式出现。

所以这个问题我在晚上或凌晨都无法解决-直到今天下午我才意识到我的JSON是错误的！！，所以难怪它不起作用！我被几个提供JSON的不同API搞混了。感谢那些指出类看起来是错误的人，让我重新检查了我的代码，并意识到这个问题的简单性。需要一些橡皮鸭来发现问题。干杯

谢谢你的回答-我确实使用了这个功能（之前使用过几次该功能，都很好）也许我是在装傻，今晚我会再试试。谢谢你的回复，我肯定我以前试过这条路线
