Answer 1

从某个位置恢复数据库：

string PathToRestoreDB =  Environment.CurrentDirectory + @"\dbname.accdb";
OpenFileDialog ofd = new OpenFileDialog();
if (ofd.ShowDialog() == DialogResult.OK)
{
string Filetorestore = ofd.FileName;    // Rename Current Database to .Bak
File.Move(PathToRestoreDB, PathToRestoreDB + ".bak");     //Restore the Database From Backup Folder
File.Copy(Filetorestore, PathToRestoreDB,true);
