string appPath = Path.GetDirectoryName(Application.ExecutablePath) + @"\CatImage\";
if (Directory.Exists(appPath) == false)
{
Directory.CreateDirectory(appPath);
}
if (opFile.ShowDialog() == DialogResult.OK)
{
//try
//{
string iName = opFile.SafeFileName; // <---
string filepath = opFile.FileName;
//dbpath = appPath+ @"\" + iName;
//dbpath = dbpath.Replace(@"\\", @"\");
dbpath = iName;
MessageBox.Show(dbpath);
// MessageBox.Show(dbpath);
File.Copy(filepath, appPath + iName);
pictureBox1.Image = new Bitmap(opFile.OpenFile());
//}
//catch (Exception exp)
//{
// MessageBox.Show("Unable to open file " + exp.Message);
//}
}

{
opFile.Dispose();
}
