Question

I need to copy multiple files from a directory using a textfile that doesnt contain complete info.

NCR.txt:
Red

target directory has in it:
red1.txt
red3.txt
red44.txt

dest directory needs to have:
red1.txt
red3.txt
red44.txt

My code:

System.IO.Directory.CreateDirectory(@"C:\nPrep\" + textBox1.Text + "\\red");
        if (checkBox3.Checked)
        {
            String[] file_names = File.ReadAllLines(@"C:\NCR.txt");

            foreach (string file_name in file_names)
            {
                string[] files = Directory.GetFiles(textBox2.Text, file_name + "*.txt");
                foreach (string file in files)
                    System.IO.File.Copy(file, @"C:\nPrep\" + textBox1.Text + "\\red\\");
            }

        }

All suggestions were great and thansk for all the advise but this was perfect:

if (checkBox3.Checked)
{
    string[] lines = File.ReadAllLines(@"C:\NCR.txt");

    foreach (string line in lines)
    {
        string[] files = Directory.GetFiles(textBox2.Text, line + "*.txt");
        foreach (string file in files)
        {
             FileInfo file_info = new FileInfo(file);
             File.Copy(file, @"C:\InPrep\" + textBox1.Text + "\\text\\" + file_info.Name);
        }
    }
}
