(1)您可以将Begin
属性类型更改为DateTime
,以便更容易基于该属性类型进行过滤。DateTime的Json.Net can deserialize ISO8601日期:
public DateTime Begin { get; set; }
(2)反序列化采集后,您可以使用Linq .Where -operation对数据进行过滤,操作步骤如下:
DateTime start = DateTime.Now.AddHours(-24);
statusCollection = statusCollection.Where(r => r.Service_name == "cloud_networking" && r.Begin > start).ToList();
