Solution 1

That is what transactions are for.
Using Transactions in ADO.NET[^]

But if this is a critical system, you could need some fault tolerance and/or clustering.

Solution 2

Use a Transaction around the whole update - until you commit the transaction, no permanent update is done. If the power fails, the entire update should be lost, not just part of it.
SQL Transactions[^]
