I have a question, I am a bit new to this Linq, and I need your help.

public class getHistorialInstalaciones
    {
        public string end_date { get; set; }
        public udataHistorialInteracciones udata { get; set; }
        public fromHistorialInteracciones from { get; set; }
        public List<toHistorialInteracciones> to { get; set; }
    }

And I want to make a query with Linq that I do it like this Cases = to Deserialization in Json to the Class.

var Lista = (from r in casos
             select new
                 {
                     //toI = r.udata.To,
                     //toII = r.to,
                     //fromI = [email protected],
                     end_dateI = r.end_date,
                 }).ToList();

But I also need to bring me the value of to , from and udata.to .

How can I consult these fields?

Assuming that casos is of type List<getHistorialInstalaciones> you just have to put to what type you want that object to be added, in this case select new getHistorialInstalaciones { ... } :

var Lista = (from r in casos
    select new getHistorialInstalaciones
    {
         to = r.udata.To, // también puede ser "to = r.To", depende del que necesites
         fromI = [email protected],
         end_date = r.end_date,
    }).ToList();

Because you need to make a linq that transforms the data if you could use JsonProperty to indicate a field that is different from json.

If you use Json.NET you could implement

public class getHistorialInstalaciones
{
    [JsonProperty(PropertyName = "end_date")]
    public string end_dateI  { get; set; }

    [JsonProperty(PropertyName = "udata")]
    public udataHistorialInteracciones toI { get; set; }

    [JsonProperty(PropertyName = "from")]
    public fromHistorialInteracciones fromI { get; set; }

    [JsonProperty(PropertyName = "to")]
    public List<toHistorialInteracciones> toII { get; set; }
}

then when deserialices map with the properties of the json property but your class will have the ones you define, in this way you do not need to convert
