Advancing a timestamp by a day when an exception is encountered [closed]

In my code, I am able to delete dated files from a folder.

But the date must appear in certain *.dat files, otherwise nothing happens.

Some days are not included in these files; for example, holidays are skipped.

In this case I am encountering a problem.

So, if I am on one of these days, how can I advance to the next day after failing?

    private void button1_Click(object sender, EventArgs e)
    {
        string Destinationdead = "C:\\test\\test1";

        string todaysDate;
        todaysDate = dateTimePicker1.Text;
        int FinalDate4 = 0;

        BLWriterClass writerdelete1 = new BLWriterClass();

        writerdelete1.OpenDirectory(Destinationdead);
        writerdelete1.OpenSecurityBySymbol(SecSymbol);
        FinalDate4 = int.Parse(todaysDate);

        {
            try
            {
                writerdelete1.OpenDirectory(Destinationdead);
                w开发者_StackOverflow社区riterdelete1.OpenSecurityBySymbol(SecSymbolbol);
                FinalDate4 = int.Parse(todaysDate);

                writerdelete1.OpenDirectory(Destinationdead);
                writerdelete1.OpenSecurityBySymbol(SecSymbol);
                int idate = Convert.ToInt32(dateTimePicker1.Text);
                int itodate = Convert.ToInt32(dateTimePicker2.Text);
                writerdelete1.DeleteSecRecords(idate, itodate);
            }
            catch (Exception)
            {

            }
        }
        writerdelete1.CloseSecurity();
        writerdelete1.CloseDirectory();
    }

The problem is in your DeleteSecRecords method.

Google shows no hits for this name, so there is no way to look at it to further analyze the problem.

Edit: Ah, I understand what you are asking for. This will advance to the next day whenever an exception is encountered, until no possible days remain.

int idate = Convert.ToInt32(dateTimePicker1.Text);
int itodate = Convert.ToInt32(dateTimePicker2.Text);

while (idate <= itodate) {
    try
    {
        writerdelete1.OpenDirectory(Destinationdead);
        writerdelete1.OpenSecurityBySymbol(SecSymbolbol);
        FinalDate4 = int.Parse(todaysDate);

        writerdelete1.OpenDirectory(Destinationdead);
        writerdelete1.OpenSecurityBySymbol(SecSymbol);
        writerdelete1.DeleteSecRecords(idate, itodate);

        break;
    }
    catch (Exception)
    {
        idate += 60 * 60 * 24; // advance by one day
        continue;
    }
}
