Populate listbox with the next 30 dates from current date

I'm trying to populate my listbox from today's date until the next 30 days. My current code populates my textbox from the current month. How do I only get the value of the date today until the next 30 days.

int year = 2018;
int month = 2;

DateTime date = new DateTime(year, month, 1);
//DateTime Today = DateTime.Today;
//DateTime expiryDate = Today.AddDays(30);
do
{

    date = date.AddDays(1);
    var dateonly = date.ToShortDateString();
    listBox1.Items.Add(dateonly);
}
while (date.Month == month);

You can use Enumerable.Range:

    DateTime date = new DateTime(year, month, 1);
    Enumerable.Range(0, 30).ToList().ForEach(day => listBox1.Items.Add(date.AddDays(day).ToShortDateString()));

So you are aware about the limit(here 30 days). Then why not something like this, by using a counter?

DateTime currentDate = DateTime.Now;
for (int dayCount = 1; dayCount <= 30; dayCount++)
{
   var date = currentDate.AddDays(dayCount);
    var dateonly = date.ToShortDateString();
    listBox1.Items.Add(dateonly);
}

The for loop should be for (int dayCount = 0; dayCount < 30; dayCount++) if you want to include current date in the list
