Represents a Transact-SQL transaction to be made in a SQL Server database. This class cannot be inherited.

Namespace:  System.Data.SqlClient
Assembly:  System.Data (in System.Data.dll)
public ref class SqlTransaction sealed : public DbTransaction

The SqlTransaction type exposes the following members.

  NameDescription
Public propertyConnectionGets the SqlConnection object associated with the transaction, or nullptr if the transaction is no longer valid.
Protected propertyDbConnectionSpecifies the DbConnection object associated with the transaction. (Inherited from DbTransaction.)
Public propertyIsolationLevelSpecifies the IsolationLevel for this transaction. (Overrides DbTransaction::IsolationLevel.)

  NameDescription
Public methodCommitCommits the database transaction. (Overrides DbTransaction::Commit().)
Public methodCreateObjRefCreates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from MarshalByRefObject.)
Public methodDispose()Releases the unmanaged resources used by the DbTransaction. (Inherited from DbTransaction.)
Protected methodDispose(Boolean)Releases the unmanaged resources used by the DbTransaction and optionally releases the managed resources. (Inherited from DbTransaction.)
Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetLifetimeServiceRetrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodInitializeLifetimeServiceObtains a lifetime service object to control the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
Protected methodMemberwiseClone()Creates a shallow copy of the current Object. (Inherited from Object.)
Protected methodMemberwiseClone(Boolean)Creates a shallow copy of the current MarshalByRefObject object. (Inherited from MarshalByRefObject.)
Public methodRollback()Rolls back a transaction from a pending state. (Overrides DbTransaction::Rollback().)
Public methodRollback(String)Rolls back a transaction from a pending state, and specifies the transaction or savepoint name.
Public methodSaveCreates a savepoint in the transaction that can be used to roll back a part of the transaction, and specifies the savepoint name.
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

The application creates a SqlTransaction object by calling BeginTransaction on the SqlConnection object. All subsequent operations associated with the transaction (for example, committing or aborting the transaction), are performed on the SqlTransaction object.

NoteNote

Try/Catch exception handling should always be used when committing or rolling back a SqlTransaction. Both Commit and Rollback generate 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 2005 Books Online.

The following example creates a SqlConnection and a SqlTransaction. It also demonstrates how to use the BeginTransaction, Commit, 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.
