GetSunday

This code will provide the Sunday DateTime from the week of DateTime object the extension method is called from.

Source

public static DateTime GetSunday(this DateTime dt)
{
    DateTime date = new DateTime(dt.Year, dt.Month, dt.Day, dt.Hour, dt.Minute, dt.Second);
    return new GregorianCalendar().AddDays(date, -((int)date.DayOfWeek));
}

Example

DateTime oldDate = new DateTime(2017,5,5);
DateTime Sunday = oldDate.GetSunday();

results in a value of 2017-April-30 which is correct in this instance.
