Question

I have used this to save my file

string m_strDate = DateTime.Now.ToString("MM/dd/yyyy");
m_strDate = m_strDate.Replace("/", "");
strPath += "/FileHeader_" + m_strDate + ".txt";

So as per this I can save a file per day. But if I create for another time the data in that text file is getting replaced by the new one. Now what I need is I would like to save my file with some name along with date and a number like

"/FileHeader_1" + m_strDate + ".txt"

and so on.

Answer 1

string fileName = "/FileHeader_" + m_strDate + ".txt";
if (File.Exists(fileName))
{
  int index = 1;
  fileName = "/FileHeader_" + index + m_strDate + ".txt";
  while (File.Exists(fileName))
    fileName = "/FileHeader_" + ++index + m_strDate + ".txt";
}
