备份和还原SQLCE .sdf数据库

Question

My application needs to backup and restore .sdf files. There is a single dataSet the the whole application and some bindngSource and table adapters on forms using this same dataset.

Just for a sake of test I tryied to copy the .sdf in runtime for a backup folder and back to restore it and I got my application not finding the file like it was not there anymore.

How should I manage connections to open and close the database since the dataSet do it automaticaly at begin and end of my application?

assign the OpenFileDialog.RestoreDirectory flag to true and then after it closes the original directory will be restored prior to the open dialog....that way you don't need the Directory.SetCurrentDirectory.

fileChooser = new OpenFileDialog();
fileChooser.RestoreDirectory = true;
