Get day of week from current date and specifying first day of week

I am migrating a legacy VB6 project into C#.

I want to obtain the equivalent in C# from expression below:

Weekday(Date, vbMonday)

I know there is a function in C#:

int dayOfWeek = (int)DateTime.Today.DayOfWeek;

but how to specify that the first day of the week is Monday and then function DayOfWeek take it into account and return the correct value?

I need to obtain an int value.

DateTime dateValue = new DateTime(2008, 6, 11);



Console.WriteLine((int) dateValue.DayOfWeek);

// The example displays the following output: // 3 

Console.WriteLine(dateValue.ToString("dddd"));

// The example displays the following output: // Wed

Console.WriteLine(dateValue.ToString("dddd"));

// The example displays the following output: // Wednesday

You can get the first day of the week by calling CultureInfo.CurrentCulture.DateTimeFormat.FirstDayOfWeek, but I think you can do without that.

The Weekday function returns 1 for Monday, just like DayOfWeek. The only special case is Sunday, which .NET returns as 0, while VB returns 7.

Just do the math:

int dayOfWeek = DateTime.Today.DayOfWeek == DayOfWeek.Sunday
                 ? 7
                 : (int)DateTime.Today.DayOfWeek;
