Store many objects of the same type on disk?

Question

Database

JSON

{
  "count": 10, //количество элементов
  "Event": 
  [//GameEvent Array
    {
      "ID": 0,
      "Text": "Hello!"
      {//EventInfo
        "TimeOut": 0
      }
    }
    {
      "ID": 1,
      "Text": "I keep data."
      {
      "TimeOut": 42
      }
    }
    //...
  ]
}

C#

DataContract]
    public sealed class GameEvent
    {
        [DataMember]
        public EventInfo EventInfo { get; }
        [DataMember]
        public string Text { get; }

        internal GameEvent(string text, EventInfo ei)
        {
            Text = text;
            EventInfo = ei;
        }

        internal GameEvent(string text)
            : this(text, default(EventInfo))
        { }
    }

[DataContract()]
    public struct EventInfo
    {
        [DataMember]
        TimeSpan TimeOut;

        internal EventInfo(TimeSpan timeOut)
        {
            TimeOut = timeOut;
        }
    }

How to serialize a single object (GameEvent) by ID? (There are a lot of elements planned, and I don't want to keep them in memory.)
Maybe try a database? How to create it without installed special programs. And how to address it from the code?

Answer 1

Maybe try db? How to create it without installed special programs.

It depends on which database ..
If you store data in files, then it is better to use JSON

Answer 2

Try https://github.com/google/protobuf
Cool stuff - very fast.
