random numbers

[Shani Aulakh]

The following code is generating files perfectly, But when i change the date on my laptop to get files with different modified times. It just overrides all the files with the recent date.

        private void GenerateTestFiles_Click(object sender, EventArgs e)
        {
            StreamWriter outStream = null;
            string message = null;
 
            for (int i = 0; i < (100); i++)
            {
                string filename = "output";
                filename += i.ToString();
 
                if (i % 3 == 0)
                {//multiple of three
                    filename += ".txt";
                }
                else if (i % 5 == 0)
                {//multiple of 5
                    filename += ".log";
                }
                else if (i % 7 == 0)
                {// multiple of 7
                    filename += ".exe";
                }
                else if (i % 9 == 0)
                {// miltiple of 9
                    filename += ".dat";
                }
                else if (i % 11 == 0)
                {// multiple of 11
                    filename += ".jpq";
                }
                else
                {
                    filename += ".bmp";
                }
 
                FolderWatcher fw = new FolderWatcher();
                filename = fw.FolderPath + "C:\\CsharpTempFolder\\" + filename;
 
                try
                {
                    outStream = new StreamWriter(filename);
                    outStream.WriteLine("Hello World");
                    outStream.Close();
                }
                catch (Exception Ex)
                {
                    message = "Unable to create " + filename + "\r\n";
                    message += String.Format("Reason: {0}", Ex.Message);
                    MessageBox.Show(message);
                }
            }
        }
 

1. Can i generate files with random numbers. Like, in the loop i takes random values using System.Random class. Or, add datetime object. what is the most simpliest way of doing it.

The following c# function will generate a random file name for you:
Path.GetRandomF ileName();

The following c# function will generate a random file name for you:
Path.GetRandomF ileName();

Wow, I was un-aware of that function.
