Check if dateTime is a weekend or a weekday
Solution 1:
You wrote wrong varable in the following if statement:
if ((dayToday == DayOfWeek.Saturday) || (dayToday == DayOfWeek.Sunday))
{
Console.WriteLine("This is a weekend");
}
instead of dayToday you must use day varable in the condition.
UPDATE:
Also you made mistake in condition. There must be or
instead of and
.
Correct code is
if ((day == DayOfWeek.Saturday) || (day == DayOfWeek.Sunday))
{
Console.WriteLine("This is a weekend");
}
Solution 2:
You are comparing your ASP.NET label dayToday
against an enumeration element of DayOfWeek
which of course fails
Probably you want to replace dayToday
with day
in your if
statement, i.e. from
if ((dayToday == DayOfWeek.Saturday) && (dayToday == DayOfWeek.Sunday))
to
if ((day == DayOfWeek.Saturday) && (day == DayOfWeek.Sunday))
In addition, you probably also want to replace the logical 'and' (&&
) with a logical 'or' (||
) to finally
if ((day == DayOfWeek.Saturday) || (day == DayOfWeek.Sunday))
Solution 3:
if ((day >= DayOfWeek.Monday) && (day<= DayOfWeek.Friday))
{
// action
}
Solution 4:
You are receiving an error because you are comparing an enum with a string.
// dayToday is a string
// DayOfWeek.Saturday is an enum
if ((dayToday == DayOfWeek.Saturday) && (dayToday == DayOfWeek.Sunday))
Use DayOfWeek.Saturday.ToString()
to compare against a string. You will also want not to pad the dayToday
string. Alternatively, use the day
variable to compare against an enum.

public class Program

public static void Main()

DateTime date = DateTime.Now;
string dateToday = date.ToString("d");
DayOfWeek day = DateTime.Now.DayOfWeek;
string dayToday = day.ToString();
// compare enums
if ((day == DayOfWeek.Saturday) || (day == DayOfWeek.Sunday))
{
Console.WriteLine(dateToday + " is a weekend");
}
else
{
Console.WriteLine(dateToday + " is not a weekend");
}
// compare strings
if ((dayToday == DayOfWeek.Saturday.ToString()) || (dayToday == DayOfWeek.Sunday.ToString()))
{
Console.WriteLine(dateToday + " is a weekend");
}
else
{
Console.WriteLine(dateToday + " is not a weekend");
}
}
}
