How to fix file .json not found

I am trying here to consume the data from a JSON file:

DATA.json

[

{"Label"
        
        :"USA",
        "Adress":"This is the us",
        "Lat":"36.9628066",
        "Lng":"-122.0194722"
},
{ "Label"  :"USA",
         "Address":"2020",
          "Lat":"36.9628066", 
          "Lng":"-122.0194722" }

]

Then applying it in my Mainclass:

using System.Collections.Generic;
using Xamarin.Forms.Maps;
using Xamarin.Forms;
using System.IO;
using Newtonsoft.Json;
using System;


namespace Orbage
{
    

class MapPage : ContentPage
    {
        public MapPage()
        {
            CustomMap customMap = new CustomMap
            {
                MapType = MapType.Street

            };
            // ...
            Content = customMap;

            var json = File.ReadAllText("File.json");
            var places = JsonConvert.DeserializeObject<List<File>>(json);
            foreach (var place in places)
            {
                CustomPin pin = new CustomPin
                {
                    Type = PinType.Place,
                    Position = new Position(Double.Parse(place.Lat), Double.Parse(place.Lng)),
                    Label = place.Label,
                    Address = place.Address,
                    Name = "Xamarin",

                    Url = "http://xamarin.com/about/"
                };



                customMap.CustomPins = new List<CustomPin> { pin };

                customMap.Pins.Add(pin);
                customMap.MoveToRegion(MapSpan.FromCenterAndRadius(new Position(37.79752, -122.40183), Distance.FromMiles(1.0)));
            }
        }
    }


}

But when I put the file in there it says that it doesn't exist.

Error:

FilenotfoundException

Whats the fix for this.
I tried:

• Changing the location of the file.
• Its name = Instead of E:/-/- I even wrote file.json but I still get the same error.
