Represents a Transact-SQL transaction to be made in a SQL Server database. This class cannot be inherited.
Assembly: System.Data (in System.Data.dll)
Thetype exposes the following members.
|Connection||Gets the SqlConnection object associated with the transaction, or a null reference (Nothing in Visual Basic) if the transaction is no longer valid.|
|DbConnection||Specifies the DbConnection object associated with the transaction. (Inherited from DbTransaction.)|
|IsolationLevel||Specifies the IsolationLevel for this transaction. (Overrides DbTransaction.IsolationLevel.)|
|Commit||Commits the database transaction. (Overrides DbTransaction.Commit().)|
|CreateObjRef||Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from MarshalByRefObject.)|
|Dispose()||Releases the unmanaged resources used by the DbTransaction. (Inherited from DbTransaction.)|
|Dispose(Boolean)||Releases the unmanaged resources used by the DbTransaction and optionally releases the managed resources. (Inherited from DbTransaction.)|
|Equals(Object)||Determines whether the specified Object is equal to the current Object. (Inherited from Object.)|
|Finalize||Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)|
|GetHashCode||Serves as a hash function for a particular type. (Inherited from Object.)|
|GetLifetimeService||Retrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from MarshalByRefObject.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|InitializeLifetimeService||Obtains a lifetime service object to control the lifetime policy for this instance. (Inherited from MarshalByRefObject.)|
|MemberwiseClone()||Creates a shallow copy of the current Object. (Inherited from Object.)|
|MemberwiseClone(Boolean)||Creates a shallow copy of the current MarshalByRefObject object. (Inherited from MarshalByRefObject.)|
|Rollback()||Rolls back a transaction from a pending state. (Overrides DbTransaction.Rollback().)|
|Rollback(String)||Rolls back a transaction from a pending state, and specifies the transaction or savepoint name.|
|Save||Creates a savepoint in the transaction that can be used to roll back a part of the transaction, and specifies the savepoint name.|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
The application creates a 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 object.
Try/Catch exception handling should always be used when committing or rolling back a . Both Commit and Rollback generate an InvalidOperationException if the connection is terminated or if the transaction has already been rolled back on the server.

The following example creates a SqlConnection and a . 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.
