How to get a random date in C#

I looked everywhere for a sample on generating random dates in C# but could find any so I wrote mine.

private static DateTime getRandomDate(Random rand, 
    DateTime minDate, DateTime maxDate)
{
    int totalDays = (int)DateTimeUtil.DateDiff(
        DateInterval.Day , minDate, maxDate);
    int randomDays = rand.Next(0,totalDays);
    return minDate.AddDays(randomDays);

}

This function uses the DateTime utility class below which I found somewhere on the web.

    public enum DateInterval
    {
        Day,
        DayOfYear,
        Hour,
        Minute,
        Month,
        Quarter,
        Second,
        Weekday,
        WeekOfYear,
        Year
    }

///

    public sealed class DateTimeUtil
    {

        #region DateDiff Methods

        public static long DateDiff(DateInterval interval, 
            DateTime dt1, DateTime dt2)
        {

            return DateDiff(interval, dt1, dt2, System.Globalization
                .DateTimeFormatInfo.CurrentInfo.FirstDayOfWeek);

        }

        private static int GetQuarter(int nMonth)
        {
            if (nMonth <= 3)
                return 1;
            if (nMonth <= 6)
                return 2;
            if (nMonth <= 9)
                return 3;
            return 4;
        }

        public static long DateDiff(DateInterval interval, 
            DateTime dt1, DateTime dt2, DayOfWeek eFirstDayOfWeek)
        {

            if (interval == DateInterval.Year)

                return dt2.Year - dt1.Year;

            if (interval == DateInterval.Month)

                return (dt2.Month - dt1.Month) + 
                    (12 * (dt2.Year - dt1.Year));

            TimeSpan ts = dt2 - dt1;

            if (interval == DateInterval.Day || 
                interval == DateInterval.DayOfYear)
                return Round(ts.TotalDays);

Visual Studio is a memory hog - uses 1/2 a gig of memory

Visual Studio (2005) and ASP.NET server are using more than 1/3 (765,304k) of all my memory. Has Microsoft lost its mind?
