I would like to change in an existing content one condition to a little bit more flexible and struggel here.:

the original looks like:

if (object.dayofweek == DayOfWeek.Tuesday)
{
}

my first approach was to replace Tuesday by an integer, but this fails. Then I've tried to use:

if (object.dayofweek == Enum.GetName(typeof(DayOfWeek), 2))
{
}

does not work.

Any hint, how I can replace the fixed day by an variable? Thanks!

    Replacing a named constant (`Tuesday`) with a [magic number](https://en.wikipedia.org/wiki/Magic_number_(programming)#Unnamed_numerical_constants) (`2`) is the opposite of being more flexible. What do you [actually](https://meta.stackexchange.com/q/66377/147640) want to achieve? – GSerg Jan 25 '21 at 10:54
  • What type is _object_? I Assume is a DateTime variable but in this case _object.DayOfWeek_ should be correctly capitalized. – Steve Jan 25 '21 at 10:56

You need a way to get the current day of the week. That could be done with

DateTime.Today.DayOfWeek

If you're using that, then you can keep using DayOfWeek.Tuesday, like this:

if (DateTime.Today.DayOfWeek == DayOfWeek.Tuesday)

And in case you want to know how to change an enum to a variable, use (int)DayOfWeek.Tuesday

(DayOfWeek)myInteger – Klaus Gütter

This is the solution, a simple type conversion.

so the result would be:

if (DateTime.Today.DayOfWeek == (DayOfWeek)2) // for instance in case of Tuesday
