TransactionAttribute Class
Specifies the type of transaction that is available to the attributed object. Permissible values are members of the TransactionOption enumeration.
Assembly: System.EnterpriseServices (in System.EnterpriseServices.dll)
The TransactionAttribute type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | TransactionAttribute() | Initializes a new instance of the TransactionAttribute class, setting the component's requested transaction type to Required. |
![]() | TransactionAttribute(TransactionOption) | Initializes a new instance of the TransactionAttribute class, specifying the transaction type. |
| Name | Description | |
|---|---|---|
![]() | Isolation | Gets or sets the transaction isolation level. |
![]() | Timeout | Gets or sets the time-out for this transaction. |
![]() | TypeId | When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.) |
![]() | Value | Gets the TransactionOption value for the transaction, optionally disabling the transaction service. |
| Name | Description | |
|---|---|---|
![]() | Equals | Infrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.) |
![]() | 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 | Returns the hash code for this instance. (Inherited from Attribute.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | IsDefaultAttribute | When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.) |
![]() | Match | When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
| Name | Description | |
|---|---|---|
![]() ![]() | _Attribute::GetIDsOfNames | Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.) |
![]() ![]() | _Attribute::GetTypeInfo | Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.) |
![]() ![]() | _Attribute::GetTypeInfoCount | Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.) |
![]() ![]() | _Attribute::Invoke | Provides access to properties and methods exposed by an object. (Inherited from Attribute.) |
If a transaction type is specified with this attribute, it must not be changed in the COM+ catalog. If the transaction type is changed in the COM+ catalog, the same transaction type must be specified on the component with this attribute.

The following code example demonstrates the use of the TransactionAttribute to mark a ServicedComponent as transactional.
[assembly:System::Reflection::AssemblyKeyFile("Transaction.snk")]; [Transaction] public ref class TransactionalComponent: public ServicedComponent { public: void TransactionalMethod( String^ data ) { ContextUtil::DeactivateOnReturn = true; ContextUtil::MyTransactionVote = TransactionVote::Abort; // do work with data ContextUtil::MyTransactionVote = TransactionVote::Commit; } };
Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows XP SP2 x64 Edition, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
The .NET Framework does not support all versions of every platform. For a list of the supported versions, see .NET Framework System Requirements.
