C#中读取和解析JSON文件？

public void LoadJson()
{
    using (StreamReader r = new StreamReader("file.json"))
    {
        string json = r.ReadToEnd();
        List<Item> items = JsonConvert.DeserializeObject<List<Item>>(json);
    }
}

public class Item
{
    public int millis;
    public string stamp;
    public DateTime datetime;
    public string light;
    public float temp;
    public float vcc;
}

你甚至可以在 C# dynamic 不声明 C# Item类的情况下获取

dynamic array = JsonConvert.DeserializeObject(json);
foreach(var item in array)
{
    Console.WriteLine("{0} {1}", item.temp, item.vcc);
}







dynamic ckeckDate = Newtonsoft.Json.JsonConvert.DeserializeObject<dynamic>(ckeckDate_list);//查询条件
string txtbilltype = ckeckDate.txtbilltype;
string txttransname = ckeckDate.txttransname;
