C# button extract embedded files

For File Copy, you need to use

System.IO;

If I am not wrong, probably you want to copy files from one place to another on a button click.
If this is the case, you can create a Button Click event handler and put a similar code like this;

  private void btn_Extract_Click(object sender, EventArgs e)
  {
  string sourceDirectory = @"D:\temp\";
  string destinationDirectory = @"D:\temp\Hemant\";
  if (!Directory.Exists(destinationDirectory))
  {
  Directory.CreateDirectory(destinationDirectory);
  }
 
  // Copying the info.txt file from 'D:\temp\' to 'D:\temp\Hemant\'
  File.Copy(sourceDirectory + "info.txt", destinationDirectory + "info.txt",true);
  }


Note: Here your source folder would be your folder (what you see in the solution explorer)
