Below is a working code snippet:
string data = Encoding.UTF8.GetString(eventData.GetBytes());
JObject o = JObject.Parse(data);
var disp = db.Dispositivos
.Where(p => p.ClaveDispositivo == "UM5WOkRIFtS9dWbM5f1YM/ncpdrpSYrh3zND9Y/YHM4=");
if(disp.ToList().Count > 0)
{
// ...
However, when attempting to replace the hard-coded value with a variable:
string data = Encoding.UTF8.GetString(eventData.GetBytes());
JObject o = JObject.Parse(data);
var disp = db.Dispositivos
.Where(p => p.ClaveDispositivo == o["deviceKey"].ToString());
if(disp.ToList().Count > 0)
{
// ...
An error is encountered:
LINQ to Entities does not recognize the method 'Newtonsoft.Json.Linq.JToken get_Item(System.String)' method.
