Creating copy of uploaded file

Question

How to create a copy of a file that is uploaded using OpenFileDialog Box .I have to save that copy in a folder.

 

private void button1_Click(object sender, EventArgs e)

{

OpenFileDialog op1 = new OpenFileDialog();

op1.Multiselect = false;

op1.InitialDirectory = Application.StartupPath;

op1.ShowDialog();

op1.Filter = "allfiles|*.bin";

if (op1.ShowDialog() == DialogResult.OK)

{

string name = op1.FileName;

 MessageBox.Show("FileName is", name);

System.IO.File.Copy(name, Path.Combine(Path.GetDirectoryName(name), Path.GetFileNameWithoutExtension(name) + ".bin"));

//op1.Save(Application.StartupPath + @"\Code_" + DateTime.Now.ToString("d_MM_yy_HH_mm_ss") + ".bin");

}

}
