get properties through a string object with c # - Xamarin forms

Question

I have an object of 500 properties, my need is to call the object dynamically using string. How can I do using c #?

public class MyObjects
    {    
    public int RGP_Id { get; set; }
    public DateTime RGP_DateTime { get; set; }
    public int RGP_MCC_Numero_Serie_MS { get; set; }
    public int RGP_IDREG_1 { get; set; }
    public int RGP_IDREG_2 { get; set; }
    public int RGP_IDREG_3 { get; set; }
    public int RGP_IDREG_4 { get; set; }
    public int RGP_IDREG_5 { get; set; }
    public int RGP_IDREG_6 { get; set; }
    public int RGP_IDREG_7 { get; set; }
    public int RGP_IDREG_8 { get; set; }
    public int RGP_IDREG_9 { get; set; }
    public int RGP_IDREG_10 { get; set; }
    .......
    public int RGP_IDREG_500 { get; set; }

}

I would need to call the object's properties and return its value, using string.

target example:

var x = MyObjects.GetPropertyValue("RGP_IDREG_10");

it's possible ?

The demonstrated goal isn't really clear to me. You want a `static` method called `Equals()` which takes a `string` and does what exactly? What would `x` be after this operation? — David, Feb 28 '17 at 13:40

it's not a duplicate @David this is for xamarin forms....GetProperty() not exist in xamarin forms c# — Mr. Developer, Feb 28 '17 at 13:46
Interesting. Can you elaborate on how you've attempted to use that solution and in what way it failed? — David, Feb 28 '17 at 13:47
I am trying with the GetType () but does not have methods that can retrieve a value by string, the reflection I can not use it because the .net xaamrin forms does not support this feature fully. — Mr. Developer, Feb 28 '17 at 13:50
@Mr. Developer Did you think about using a `List` instead of 500 properties? — Dennis Schröer, Feb 28 '17 at 13:53
Yes I thought about list, but this project is shared project and I can't change the object.. — Mr. Developer, Feb 28 '17 at 13:55
getting the property will require reflection, and reflection can be slow, esp. on mobile devices — Stephane Delcroix, Mar 01 '17 at 08:19

You could use something like this question to get the property list and then access the property. You will need to use System.Reflection but it should be available to you.

I would recommend using anything else than this, because it require reflection, and reflection might be slow, but if you really want to do it...

using System.Reflection;

...

var objects = new MyObjects();
var propertyInfo = typeof(MyObjects).GetRuntimeProperty("RGP_IDREG_1");
var value = (int)(propertyInfo.GetMethod.Invoke(objects, new object [] {}));

SOLUTION in Xamarin Forms

var profile = MyObjects;
var idProperty = GetProperty(profile.GetType().GetTypeInfo(), "RGP_IDREG_10");
var x = idProperty.GetValue(profile, null);

idProperty contain value from property

provided that `GetProperty` does what I think it does and you either mixed up the way to invoke an extension method, it doesn't returns a value, but a `PropertyInfo` – Stephane Delcroix Mar 01 '17 at 08:28
sorry, i've got correction, i'm forgot add GetValue. now works. – Mr. Developer Mar 01 '17 at 09:07
