Question

I’m using the code below to compare two Times:

DateTime systemtime = DateTime.Now;
DateTime timestart = Convert.ToDateTime(txtTimestart.Text);
DateTime timeend = Convert.ToDateTime(txtTimeend.Text);

if (systemtime < timestart || systemtime > timeend)
{
    MessageBox.Show("not auth.");
}
else
{
    MessageBox.Show("auth.");
}

But I also want to compare the current day. For example, if today is Monday or Thursday, the user is authenticated, not if otherwise. How do I do it? Thanks.

DateTime systemtime = DateTime.Now;
if(systemtime.DayOfWeek == DayOfWeek.Monday)
{

}
