如何以编程方式在 .net 备份中或还原 regedit 节点？

Question

I store (ie. persist) my app's settings in regedit, and want to be able to save them in a file, and restore later.

How can I store everything in a specific regedit node (little yellow folder on the left)?

Answer 1

There are several ways to do this. You can use regedit.exe to export it to a reg file for backup and use the file for restoring purpose.

Example to export subkeys to a reg file

regedit.exe /e c:\temp\out.reg "HKEY_CURRENT_USER\Software\Microsoft\InputPersonalization"

Or use P/Invoke to call RegSaveKey and RegRestoreKey to do this

Or use .Net Framework Microsoft.Win32.Registry to read and write values to a different file.
