This should work for you also.

class Range
{
    public DateTime Begin { get; private set; }
    public DateTime End { get; private set; }
    public Range(DateTime begin, DateTime end)
    {
        Begin = begin;
        End = end;
    }

    public bool Contains(Range range)
    {
        return range.Begin >= Begin && range.End <= End;
    }
}

and then to use it

        List ranges = new List();

        ranges.Add(new Range(DateTime.Now, DateTime.Now.AddMonths(3)));
        ranges.Add(new Range(DateTime.Now.AddMonths(3), DateTime.Now.AddMonths(6)));

        Range test = new Range(DateTime.Now.AddMonths(1), DateTime.Now.AddMonths(2));

        var hits = ranges.Where(range => range.Contains(test));

        MessageBox.Show(hits.Count().ToString());
