SqlTransaction::Commit Method

Commits the database transaction.

Namespace:  System.Data.SqlClient
Assembly:  System.Data (in System.Data.dll)

public:
virtual void Commit() override

Implements

IDbTransaction::Commit()

ExceptionCondition
Exception

An error occurred while trying to commit the transaction.

InvalidOperationException

The transaction has already been committed or rolled back.

-or-

The connection is broken.

The Commit method is equivalent to the Transact-SQL COMMIT TRANSACTION statement. You cannot roll back a transaction once it has been committed, because all modifications have become a permanent part of the database. For more information, see SQL Server Books Online.

NoteNote

Try/Catch exception handling should always be used when committing or rolling back a SqlTransaction. Both Commit and Rollback generates an InvalidOperationException if the connection is terminated or if the transaction has already been rolled back on the server.

For more information on SQL Server transactions, see "Explicit Transactions" and "Coding Efficient Transactions" in SQL Server Books Online.

The following example creates a SqlConnection and a SqlTransaction. It also demonstrates how to use the Commit, BeginTransaction, and Rollback methods. The transaction is rolled back on any error. Try/Catch error handling is used to handle any errors when attempting to commit or roll back the transaction.
