我在尝试反序列化 JSON 对象时遇到困难。
我正在从 API 中读取内容作为 HttpWebRequest 和 StreamReader。我能够确认我已使用流读取器 ReadToEnd 将数据读入字符串。
但是，我似乎无法直接反序列化字符串或流读取器。我已经尝试了几乎所有我能在这里找到的例子，但我没有得到结果。我得到一个没有数据的空对象。
这是我最新的尝试。
HttpWebRequest request = WebRequest.Create("https://xxxxxx.xxx.com/api/Meeting?xxxxx") as HttpWebRequest;
request.Method = "GET";
request.ContentType = "application/JSON";
WebResponse response = request.GetResponse();
JsonSerializer ser = new JsonSerializer();
Root mtg;
StreamReader sr = new StreamReader(response.GetResponseStream());
string jsonstring = sr.ReadToEnd();
var jtr = new JsonTextReader(sr);
while(jtr.Read())
{
if(jtr.TokenType == JsonToken.StartObject)
{
mtg = ser.Deserialize<Root>(jtr);
}
}
jsonstring 包含来自 API 的数据。所以，读者正在工作。但我在 Json TextReader(sr) 上得到了 null jtr。
JSON对象属性如下：
public class Address
{
public string Line1 { get; set; }
public string City { get; set; }
public string State { get; set; }
public string Postal { get; set; }
public string Line2 { get; set; }
}
public class Agenda
{
public int ID { get; set; }
public List<Document> Documents { get; set; }
public DateTime Finalized { get; set; }
public DateTime Generated { get; set; }
public DateTime Published { get; set; }
public DateTime MeetingDate { get; set; }
public bool Revised { get; set; }
}
public class Department
{
public bool IsMeetingGroup { get; set; }
public int ID { get; set; }
public string Name { get; set; }
}
public class Document
{
public int ID { get; set; }
public string FileType { get; set; }
public DateTime FileUpdated { get; set; }
public string FileFormat { get; set; }
public string DownloadURL { get; set; }
public int FileSize { get; set; }
}
public class Location
{
public int ID { get; set; }
public string Name { get; set; }
public Address Address { get; set; }
}
public class Meeting
{
public int ID { get; set; }
public Department Department { get; set; }
public DateTime Date { get; set; }
public Type Type { get; set; }
public Location Location { get; set; }
public string Status { get; set; }
}
public class Type
{
public int ID { get; set; }
public string Name { get; set; }
}
public class Root
{
public Meeting Meeting { get; set; }
public Agenda Agenda { get; set; }
}
调用Meeting显然不起作用，调用Root显示Meeting和Agenda但它们都是空的。
我得到的字符串看起来像这样：

我正在使用 NewtwonSoft.Json，并且遇到了不同的转换实用程序。 Text.Json 等...
那么我在哪里打破了这个？
构建了我的属性这又是我第一次尝试使用内置工具反序列化 JSON，就像过去一样，我只是读取文件，然后使用大锤解码 JSON。哈哈
谢谢！
确保您的 JSON 结构与 C# 类定义匹配。如果您的 JSON 以数组开头，请将其反序列化为
List<Root>
