Assembly: System.EnterpriseServices (in System.EnterpriseServices.dll)
| 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 | |
![]() | Value | Gets the TransactionOption value for the transaction, optionally disabling the transaction service. |
| Name | Description | |
|---|---|---|
![]() | Equals(Object^) | This API supports the product infrastructure and is not intended to be used directly from your code. Returns a value that indicates whether this instance is equal to a specified object.(Inherited from Attribute.) |
![]() | GetHashCode() | Returns the hash code for this instance.(Inherited from Attribute.) |
![]() | GetType() | |
![]() | 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(Object^) | When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.) |
![]() | ToString() | Returns a string that represents the current object.(Inherited from Object.) |
| Name | Description | |
|---|---|---|
![]() ![]() | _Attribute::GetIDsOfNames(Guid%, IntPtr, UInt32, UInt32, IntPtr) | Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.) |
![]() ![]() | _Attribute::GetTypeInfo(UInt32, UInt32, IntPtr) | Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.) |
![]() ![]() | _Attribute::GetTypeInfoCount(UInt32%) | Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.) |
![]() ![]() | _Attribute::Invoke(UInt32, Guid%, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr) | 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; } };
Available since 1.1
Any public static ( Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
