数据库备份失败

Question

I'm trying to backup my database but nothing happens when i try to backup, but if i hard-code the path it works.

This method works with hard coded file path.

dbBackup.Devices.AddDevice(@"C:\Backup\saveFile.bak", DeviceType.File);

But i tried the second, the one i want the user to input the file path but it does not work and the input is exactly the same.

dbBackup.Devices.AddDevice(@"'"+ txtPath.Text +"'", DeviceType.File);

Answer 1

Adding quotes similar to how this is done with a direct T-SQL command is not necessary. The string will be correctly parsed without these. Given that the text from the hard-coded value and user input is the same as specified in your post, the following will return the same result for both.

dbBackup.Devices.AddDevice(txtPath.Text, DeviceType.File);
