      "country-id": 1000,
      "name1": {
        "name": "Afghanistan",
      },
    },
    "4000": {
      "country-id": 4000,
      "name1": {
        "name": "Albania",
      }
    }

Your json is broken and many json parser would complain about it.

I’ll use Json.Net for parsing.

    string json = @"{data: { ""1000"": { ""country-id"": 1000, ""name1"": { ""name"": ""Afghanistan"", }, }, ""4000"": { ""country-id"": 4000, ""name1"": { ""name"": ""Albania"", } }";

    var countries = ((JObject)JsonConvert.DeserializeObject(json))["data"]
        .Children()
        .Select(x => new
        {
            Id = (int)x.First()["country-id"],
            Name = (string)x.First()["name1"]["name"],
        })
        .ToList();
