How to get the integer value of day of week

Question

How do I get the day of a week in integer format? I know ToString will return only a string.

DateTime ClockInfoFromSystem = DateTime.Now;
int day1;
string day2;
day1= ClockInfoFromSystem.DayOfWeek.ToString(); /// it is not working
day2= ClockInfoFromSystem.DayOfWeek.ToString(); /// it gives me string

Answer 1

Use

day1 = (int)ClockInfoFromSystem.DayOfWeek;

Answer 2

int day = (int)DateTime.Now.DayOfWeek;

First day of the week: Sunday (with a value of zero)

Answer 3

If you want to set first day of the week to Monday with integer value 1 and Sunday with integer value 7

int day = ((int)DateTime.Now.DayOfWeek == 0) ? 7 : (int)DateTime.Now.DayOfWeek;

Answer 4

day1= (int)ClockInfoFromSystem.DayOfWeek;

Answer 5

Try this. It will work just fine:

int week = Convert.ToInt32(currentDateTime.DayOfWeek);

Answer 6

The correct way to get the integer value of an Enum such as DayOfWeek as a string is:

DayOfWeek.ToString("d")

Answer 7

Another way to get Monday with integer value 1 and Sunday with integer value 7

int day = ((int)DateTime.Now.DayOfWeek + 6) % 7 + 1;

Answer 8

The correct answer, is indeed the correct answer to get the int value.

But, if you're just checking to make sure it's Sunday for example... Consider using the following code, instead of casting to an int. This provides much more readability.

if (yourDateTimeObject.DayOfWeek == DayOfWeek.Sunday)
{
    // You can easily see you're checking for sunday, and not just "0"
}

Answer 9

DateTime currentDateTime = DateTime.Now;
int week = (int) currentDateTime.DayOfWeek;
