1. 資料結構（待補充）
2. .NET中的數字（待補充）
3. 日期時間

    public String store;
    public TimeZoneInfo tz;
    public TimeSpan open;
    public TimeSpan close;

    public bool IsOpenNow()
    {
        return IsOpenAt(DateTime.Now.TimeOfDay);
    }

    public bool IsOpenAt(TimeSpan time)
    {
        TimeZoneInfo
 
 local = TimeZoneInfo.Local;
        TimeSpan offset = TimeZoneInfo.Local.BaseUtcOffset;

        // Is the store in the same time zone?
        if (tz.Equals(local))
        {
            return time >= open & time <= close;
        }
        else
        {
            TimeSpan delta = TimeSpan.
 
Zero;
            TimeSpan storeDelta = TimeSpan.Zero;

            // Is it daylight saving time in either time zone?
            if (local.IsDaylightSavingTime(DateTime.Now.Date + time))
                delta = local.GetAdjustmentRules()[local.GetAdjustmentRules().Length - 1].DaylightDelta;

            if
 
 (tz.IsDaylightSavingTime(TimeZoneInfo.ConvertTime(DateTime.Now.Date + time, local, tz)))
                storeDelta = tz.GetAdjustmentRules()[local.GetAdjustmentRules().Length - 1].DaylightDelta;

            TimeSpan comparisonTime = time + (offset - tz.BaseUtcOffset).Negate() + (delta - storeDelta).Negate();
            return comparisonTime >= open & comparisonTime <= close;
        }
    }

4. 事件（ EventArgs gg; IObservable 介面）
5. 特型（待補充）
6. 框架使用準則（省略）
7. XML和其序列化（待補充）
8. 二進位制序列化

        MyObject obj = new MyObject();
        obj.n1 = 1;
        obj.n2 = 24;
        obj.str = "Some String";
        IFormatter formatter = new BinaryFormatter();
        Stream stream = new FileStream("MyFile.bin", FileMode.Create, FileAccess.Write, FileShare.None);
        formatter.Serialize(stream, obj);
        stream.Close();

        //反序列化
        IFormatter formatter2 = new BinaryFormatter();
        Stream stream2 = new FileStream("MyFile.bin", FileMode.Open, FileAccess.Read, FileShare.Read);
        MyObject obj2 = (MyObject)formatter.Deserialize(stream);
        stream.Close();
        //序列化有4個回撥函式
