Specifies the type of transaction that is available to the attributed object. Permissible values are members of the TransactionOption enumeration.
<ComVisibleAttribute(False)> _ <AttributeUsageAttribute(AttributeTargets.Class, Inherited := True)> _ Public NotInheritable Class TransactionAttribute _ Inherits Attribute
Dim instance As TransactionAttribute
[ComVisibleAttribute(false)] [AttributeUsageAttribute(AttributeTargets.Class, Inherited = true)] public sealed class TransactionAttribute : Attribute
[ComVisibleAttribute(false)] [AttributeUsageAttribute(AttributeTargets::Class, Inherited = true)] public ref class TransactionAttribute sealed : public Attribute
public final class TransactionAttribute extends 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.
For more information about using attributes, see Extending Metadata Using Attributes.
The following code example demonstrates the use of the TransactionAttribute to mark a ServicedComponent as transactional.
<Transaction()> _ Public Class TransactionalComponent Inherits ServicedComponent Public Sub TransactionalMethod(ByVal data As String) ContextUtil.DeactivateOnReturn = True ContextUtil.MyTransactionVote = TransactionVote.Abort ' Do work with data. Return if any errors occur. ' Vote to commit. If any errors occur, this code will not execute. ContextUtil.MyTransactionVote = TransactionVote.Commit End Sub 'TransactionalMethod End Class 'TransactionalComponent
[Transaction] public class TransactionalComponent : ServicedComponent { public void TransactionalMethod (string data) { ContextUtil.DeactivateOnReturn = true; ContextUtil.MyTransactionVote = TransactionVote.Abort; // Do work with data. Return if any errors occur. // Vote to commit. If any errors occur, this code will not execute. ContextUtil.MyTransactionVote = TransactionVote.Commit; } }
[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; } };
[Transaction] public __gc class TransactionalComponent : public ServicedComponent { public: void TransactionalMethod (String* data) { ContextUtil::DeactivateOnReturn = true; ContextUtil::MyTransactionVote = TransactionVote::Abort; // do work with data ContextUtil::MyTransactionVote = TransactionVote::Commit; } };
