将自定义类序列化到文件

Question

I'm writing a save method for my Player class, I can serialize most fields using a binary writer however my custom class fields are not able to be serialized (i have a Race field for custom races)

Since I am going to have a lot of different custom classes - like Race - I really need a good reliable way of saving this information.

So, am I using the wrong kind of formatter? And if so, what is the one I should be using? Alternatively, how do I write the method to serialize it? I have used the [Serializable()] attribute and implemented ISerializable interface where needed already.

Here is the code:

public void Save()
{
    Stream stream = File.Open(SaveSlot, FileMode.Create);
    BinaryWriter writer = new BinaryWriter(stream);
    PlayerData saveData = new PlayerData();

    writer.Write(saveData.Name = PlayerData.player.Name);
    writer.Write(saveData.Race = PlayerData.player.Race);
    writer.Write(saveData.PlayClass = PlayerData.player.PlayClass);
    writer.Write(saveData.Level = PlayerData.player.Level);
    writer.Write(saveData.Experience = PlayerData.player.Experience);
    writer.Write(saveData.Strength = PlayerData.player.Strength);
    writer.Write(saveData.Dexterity = PlayerData.player.Dexterity);
    writer.Write(saveData.Constitution = PlayerData.player.Constitution);
    writer.Write(saveData.Intelligence = PlayerData.player.Intelligence);
    writer.Write(saveData.Wisdom = PlayerData.player.Wisdom);
    writer.Write(saveData.Charisma = PlayerData.player.Charisma);
    writer.Write(saveData.Wounds = PlayerData.player.Wounds);
    writer.Write(saveData.MaxWounds = PlayerData.player.MaxWounds);
    writer.Write(saveData.Attackbonus = PlayerData.player.Attackbonus);
    writer.Write(saveData.Defensebonus = PlayerData.player.Defensebonus);

    writer.Close();
    Console.WriteLine("Data Saved Successfully");
}

Like I said in my comment you can use the json format for this.

Sample class

public class MyObject
{
    public string MyProperty { get; set; }
}

Sample data

List<MyObject> objects = new List<MyObject>
{
    new MyObject{MyProperty = "test 1"},
    new MyObject{MyProperty = "test 2"},
    new MyObject{MyProperty = "test 3"}
};

Sample code

Then you can use this code for serialize your data (using Newtonsoft ).

string json = JsonConvert.SerializeObject(objects);

The content of json will be

[{"MyProperty":"test 1"},{"MyProperty":"test 2"},{"MyProperty":"test 3"}]

If you want to deserialize the string use this.

List<MyObject> deserialzed = JsonConvert.DeserializeObject<List<MyObject>>(json);

More info

You can save the json string to a file and load and deserialize it when you need it. This works with every type of a property including list and custom objects.

Have a read at the JSON format for more information.
