将Json反序列化到数据集中的唯一方法是首先从数据集中序列化它。相反，您可以创建一个使用Json的类。为此，将Json复制到剪贴板中，在Visual Studio中创建一个新的.Json文件，单击“编辑”菜单，转到“粘贴特殊”，然后将Json粘贴为类。对我来说，它产生了
public class Class1
{
public string title { get; set; }
public string pubDate { get; set; }
public string link { get; set; }
public string guid { get; set; }
public string author { get; set; }
public string thumbnail { get; set; }
public string description { get; set; }
public string content { get; set; }
public Enclosure enclosure { get; set; }
public object[] categories { get; set; }
}
public class Enclosure
{
public string link { get; set; }
}
var text = System.IO.File.ReadAllText("json1.json");
var items = JsonConvert.DeserializeObject<IEnumerable<Class1>>(text);
然后，您可以使用IEnumerable代替数据集。我看不出您的JSON中有任何问题，但我注意到：第一个标题是“Grenfell改变一切”：高楼大火的阴影笼罩着英国。这个值是一种JSON格式，也许JsonConvert正在尝试转换它also@ElmerDantas我只是运行了相同的json通过我的电脑上的JsonConvert，它可以正常工作。它是一个带引号的字符串@ElmerDantas@EdPlunkett我知道它是…是一个有效的json，但正如我所说的，json转换器正试图将json内部的这一部分转换为json，这也是一个疑问。您所能做的最好的事情就是创建一个具有所需属性的对象，然后使用该对象进行反序列化@是埃尔默丹塔斯，还是你只是想知道是不是？你能给我看一个演示这个bug的特殊序列化程序的例子吗？
