Firstly, don''t title your question "Hi Everybody" - it tells us nothing about what your problem is. Use "How to copy a file?" or similar.

Use File.Copy[^]

Hi kikhatri, the below is the code to copy the file one location to another. Hope this would help you.

private void button1_Click(object sender, EventArgs e)
{
StreamReader objReader = new StreamReader("C:\\Hello.txt");
string sLine =string.Empty;
ArrayList arrText = new ArrayList();
while (objReader.Peek() == 72)
{
sLine = objReader.ReadLine();
if (sLine != "")
arrText.Add(sLine);
}
FileInfo fi = new FileInfo("D:\\Hello.txt");
// Actually create the file.
FileStream fs = fi.Create();
Byte[] fb =
new UTF8Encoding(true).GetBytes(arrText.ToString());
fs.Write(fb, 0, fb.Length);
// Modify the file as required, and then close the file.
fs.Close();
}
