Try it code:

System.Resources.ResourceManager rm = typeof(AppResources)
            .GetRuntimeFields()
            .First(m => m.Name == "resourceMan")
            .GetValue(typeof(AppResources)) as System.Resources.ResourceManager;

//or this variant
var rm = new System.Resources.ResourceManager(typeof(AppResources));

//CultureInfo culture 
ResourceSet rs = rm.GetResourceSet(culture, true, false); 
var nameItem = rs.OfType<DictionaryEntry>().FirstOrDefault(i => i.Value == "YourValue"); 
var name = nameItem.Key.ToString();

use it in platform specific projects (Xamarin.Droid or Xamarin.iOS)

Example:

in PCL projects:

public interface IGetName
{
    string GetName (string value);
}

in Android project:

[assembly: Dependency(typeof(AppGetName ))]
namespace YourNamespace 
 ....
 public class AppGetName : IGetName
   {
       public string GetName (string value)
       {
             System.Resources.ResourceManager rm = typeof(AppResources)
                .GetRuntimeFields()
                .First(m => m.Name == "resourceMan")
                .GetValue(typeof(AppResources)) as 
      System.Resources.ResourceManager;



    //CultureInfo culture 
    ResourceSet rs = rm.GetResourceSet(culture, true, false); 
    var nameItem = rs.OfType<DictionaryEntry>().FirstOrDefault(i => i.Value == "YourValue"); 
    var name = nameItem.Key.ToString();
    return name;
       }
   }

using in PCL projects:

var getName = DependencyService.Get<IAppGetName>();
var name = getName.GetName("YourValue");

I can't find ResourceSet in Xamarin C# – Ziyad Godil Jul 28 '17 at 05:36
Do you use this code in platform specific project? – FetFrumos Jul 28 '17 at 06:01
No, It is xamarin.forms PCL project. ResourceSet class is not available. and I am not looking for Renderer. – Ziyad Godil Jul 28 '17 at 06:05
Unfortunately this code work only in platform specific project. I think you need a rendering. – FetFrumos Jul 28 '17 at 06:54
Ok, No problem thanks for the help. If you find any solution for without rendering then please let me know. I upvote you for your help :) – Ziyad Godil Jul 28 '17 at 12:22
if I use rendering then in which method I need to put above code for iOS render? – Ziyad Godil Aug 02 '17 at 13:39
I checked this code for Android. For iOS need check this code. The usage depends on your logic - see my answer I added a simple example of rendering. – FetFrumos Aug 02 '17 at 19:21
private static global::System.Resources.ResourceManager resourceMan; from AppResources.Desinger.cs – FetFrumos Aug 03 '17 at 05:01
the type and namespace could not be found "AppResources" – Ziyad Godil Aug 03 '17 at 05:04
Do you use resx file(in PCL project)? If yes - open YourFile.Designer.cs and find field private static global::System.Resources.ResourceManager resourceMan; – FetFrumos Aug 03 '17 at 05:43
