Parsing Json C#

我在WindowsPhone8应用程序中解析C#时遇到了一个大问题。

当我尝试执行这部分代码时，应用程序将关闭。当C代码反序列化JSON时，问题会附加。

见下面的代码：c(反序列化+类形式)和JSON结果。

谢谢你的回答。

public partial class MyGrades : PhoneApplicationPage
{
string token = string.Empty;
string mail = string.Empty;

public class MyGradesJson
{
[JsonProperty("periods")]
public Periods periods { get; set; }
}

public class Periods
{
[JsonProperty("period")]
public List<Perioddata> perioddata { get; set; }
}

public class Perioddata
{
[JsonProperty("period")]
public Period period { get; set; }
// [JsonProperty("name")]
// public List disciplines { get; set; }
}

public class Period
{
[JsonProperty("id")]
public int id { get; set; }
[JsonProperty("name")]
public string name { get; set; }
[JsonProperty("start_date")]
public string start_date { get; set; }
[JsonProperty("end_date")]
public string end_date { get; set; }
}

HttpResponseMessage response = await httpClient.SendAsync(requestMessage);
string responseAsString = await response.Content.ReadAsStringAsync();
var resJson = JsonConvert.DeserializeObject<Periods>(responseAsString);
}

下面是JSON的答案：
