c# json转换成dynamic对象，然后在dynamic对象中动态获取指定字符串列表中的值

using Newtonsoft.Json;

using System.Threading.Tasks;

namespace ConsoleApp1
{
class Program
{
static void Main(string[] args)
{

string ss = TestAA();
Console.WriteLine(ss);
Console.ReadKey();
}

private static string TestAA()
{
string allowAttr = string.Empty;
string json = "{"UserName":"Jack","LoS":"Beijing","Group":"34"}";
//此处模拟在不建实体类的情况下，反转将json返回成dynamic对象
var DynamicObject = JsonConvert.DeserializeObject<dynamic>(json);
//var _value = DynamicObject["LoS"];
List<string> ssList = new List<string>();
ssList.Add("LoS");
ssList.Add("Test2");
foreach(string item in ssList)
{
var value2 = DynamicObject[item];//动态获取字符串列表中的字段去dynamic对象中找对应字段的值
if(value2!=null)
{
allowAttr = string.Format("{0}{1}", value2, "_Attribute");
//string allowAttr2 = string.Format("{0}{1}", value2.Value, "_Attribute");
}
}

return allowAttr;
//Console.WriteLine(DynamicObject.LoS);
//Type Ts = DynamicObject.GetType();
//object o = Ts.GetProperty("Name").GetValue(DynamicObject, null);
//string Value = Convert.ToString(o);
//if (string.IsNullOrEmpty(Value))
//{
// return null;
//}
//else
//{
// return Value;
//}
}
}
