}示例3: GetWeekOfYearFullDays

System.Globalization.Calendar gc = new GregorianCalendar();

//
// Calculate the number of days between the first day of year (1/1) and the first day of the week.
// This value will be a positive value from 0 ~ 6. We call this value as "offset".
//
// If offset is 0, it means that the 1/1 is the start of the first week.
// Assume the first day of the week is Monday, it will look like this:
// Sun Mon Tue Wed Thu Fri Sat
// 12/31 1/1 1/2 1/3 1/4 1/5 1/6
// +--> First week starts here.
//
// If offset is 1, it means that the first day of the week is 1 day ahead of 1/1.
// Assume the first day of the week is Monday, it will look like this:
// Sun Mon Tue Wed Thu Fri Sat
// 1/1 1/2 1/3 1/4 1/5 1/6 1/7
// +--> First week starts here.
//
// If offset is 2, it means that the first day of the week is 2 days ahead of 1/1.
// Assume the first day of the week is Monday, it will look like this:
// Sat Sun Mon Tue Wed Thu Fri Sat
// 1/1 1/2 1/3 1/4 1/5 1/6 1/7 1/8
// +--> First week starts here.
// Day of week is 0-based.
// Get the day of week for 1/1. This can be derived from the day of week of the target day.
// Note that we can get a negative value. It's ok since we are going to make it a positive value when calculating the offset.
dayForJan1 = (int)gc.GetDayOfWeek(time) - (dayOfYear % 7);
// Now, calucalte the offset. Substract the first day of week from the dayForJan1. And make it a positive value.

// Calculate the day of week for the first day of the year.
// dayOfWeek - (dayOfYear % 7) is the day of week for the first day of this year. Note that
// this value can be less than 0. It's fine since we are making it positive again in calculating offset.
