I want to write a forms app, when started should create a newfile1.txt, newfile2.txt ....newfile[n].txt, at a particular location. Here "n" is hard coded, and the interval at which the new file created is controlled by a thread.

I started this as forms app with two buttons, however when I run this its going to create a single file. Can anyone toss in ideas on how to code it. Thanks

FileInfo fi = new FileInfo(@"C:\abc\file123.txt");
DirectoryInfo di = new DirectoryInfo(@"C:\abc");
private void button1_Click_1(object sender, EventArgs e)
{
            if (!di.Exists)
            {
                di.Create();
            }
            if (!fi.Exists)
            {
                fi.Create().Dispose();
            }
} 
private void button2_Click(object sender, EventArgs e)
{
            fi.Delete();
 }

C#

DirectoryInfo di = new DirectoryInfo(@"C:\abc");
int n = 10;

private void button1_Click_1(object sender, EventArgs e)
{
    if (!di.Exists) di.Create(); // Just to make sure the directory is there
    for(int idx = 1; idx<=n; idx++)
    {
        // Create a new FileInfo for each file from file1 to filen
        FileInfo fi = new FileInfo(String.Format(@"C:\abc\file{0:d}.txt", idx));
        // If that file does not exist create it
        if (!fi.Exists) fi.Create().Dispose();
    }
}
private void button2_Click(object sender, EventArgs e)
{
    if (!di.Exists) di.Create(); // Paranoia check
    foreach(FileInfo fi in di.GetFiles()) fi.Delete(); // Delete all files found in our directory
}

That should do it!

Cheers!
