if(Directory.Exists(appPath)== false)
{
Directory.CreateD irectory(appPath);
}
if(opFile.ShowDialog()== DialogResult.OK)
{
//尝试
// {
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位图(opFile.OpenFile());
