Deserializing

We will instal third party application called JSON.NET and we will need help of NuGet Package Manager to install it.

The steps:

1. Right click on our application project in Solution Explorer > Manage NuGet packages.
2. Under Browse > newtonsoft.json > Install
3. The documentation available here: http://www.newtonsoft.com/json/help/html/SerializingJSON.htm

Back to Main class. We will create method to deserialized our JSON.

First, add using namespace.

using Newtonsoft.Json;

Then, we add function to derserialized JSON.

public static List<Player> DeserializedPlayer(string fileName)
{
    var players = new List<Player>();
    var serializer = new JsonSerializer();

    return players;
}

Now we add method to read from our file. First, we read from file as usual by

using (var reader = new StreamReader(fileName))

Then, we read that text using JsonReader.

using (var jsonReader = new JsonTextReader(reader))

After that, we define our json to convert into what kind of type.

using (var jsonReader = new JsonTextReader(reader))
{
    serializer.Deserialize<List<Player>>(jsonReader);
}

Our full function should look like this.

public static List<Player> DeserializedPlayer(string fileName)
{
    var players = new List<Player>();
    var serializer = new JsonSerializer();

    using (var reader = new StreamReader(fileName))
    using (var jsonReader = new JsonTextReader(reader))
    {
        players = serializer.Deserialize<List<Player>>(jsonReader);
    }
        return players;
}

Now, back to our Main field. We will call the function.

fileName = Path.Combine(directory.FullName, "players.json");
var players = DeserializedPlayer(fileName);

foreach (var player in players)
    Console.WriteLine(player.second_name);
