How to append a number in to a file name and make it Unique?

Sujeet Raman

Hi,

I have to copy some .txt files in to a different location.But the issue is i am unable to paste those files due to same name.I am getting those .txt files from different folder.I need to append a number to make .txt file unique and paste in to different location.My current code doesnt allow this.How can i do this?

foreach (var file in Directory.EnumerateFiles(extractPathForCurrentZip, "*.txt"))
{
    File.Copy(file, DestinationFoldername+ Path.GetFileName(file));
}

You can append the counter veriable before or after file name. I have done with before like:
int counter = 1;
foreach (var file in  Directory.EnumerateFiles(extractPathForCurrentZip, "*.txt"))
{
    File.Copy(file, DestinationFoldername + counter.ToString() + "_" + Path.GetFileName(file));
    counter++;
}
