【问题描述】：
但是，当我检索单个数据条目时，我的数据可以很好地反序列化，
无法反序列化当前 JSON 对象（例如 {"name":"value"}） 进入类型'System.Collections.Generic.List`1 [Purchaseorderline]' 因为该类型需要一个 JSON 数组（例如 [1,2,3]）来反序列化 正确。
这是为了检索 Orders 和 OrderItems，我可以做一个订单（通过请求一个订单号）但是当我收到所有订单时，它会出错， 我已经执行了到 Json 对象的标准转换，以确保我的类是正确的，并且看不到我应该将什么作为数组应用到我的类中，以简单地将其放入 RootObject 类型的列表中。
这是我的代码：
{
// ... Read the string.
var result1 = await content.ReadAsStringAsync();
List<Rootobject> POOrders = new List<Rootobject>();
Rootobject test = JsonConvert.DeserializeObject<Rootobject>(result1);
POOrders.Add(test);
POOrders = JsonConvert.DeserializeObject<List<Rootobject>>(result1);
}
这里是类：
