C#: generating random files

[Shani Aulakh]

Hi All,

Can anyone help me with a method that could generate random dummy files with extensions..(.t xt, .log, .exe) in a specified folder?

Just make a series of them?
for (int i=0; i< (some number); i++)
{
string filename="dummy file"+i.ToStrin g()+".log";
//Create/populate file as needed
}

How do i use the following code to create files with different filter?

        private void button1_Click(object sender, EventArgs e)
        {
            StreamWriter outStream = null;
            string filename = "output.txt";
            string message = null;

            for (int i = 0; i < (1000); i++)
            {
                try
                {
                    outStream = new StreamWriter(filename);
                    outStream.WriteLine("Hello World");
                    outStream.Close();
                    MessageBox.Show(filename);
                }
                catch (IOException e1)
                {
                    message = "Unable to create " + filename + "\r\n";
                    message += String.Format("Reason: {0}", e1.Message);
                    MessageBox.Show(message);
                }
                message = ("File successfully created");
            }

You're only making one file there. (just doing it 1000 times)

You could switch it around the value of i maybe?

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
{
filename+=".dat";
}
