TransactionOption Enumeration
.NET Framework (current version)
Specifies the automatic transaction type requested by the component.
Assembly: System.EnterpriseServices (in System.EnterpriseServices.dll)
| Member name | Description | |
|---|---|---|
| Disabled | Ignores any transaction in the current context. | |
| NotSupported | Creates the component in a context with no governing transaction. | |
| Required | Shares a transaction, if one exists, and creates a new transaction if necessary. | |
| RequiresNew | Creates the component with a new transaction, regardless of the state of the current context. | |
| Supported | Shares a transaction, if one exists. |
When using the .NET Installation Tool (Regsvcs.exe), the transaction option for a ServicedComponent defaults to Disabled.
The following code example demonstrates the use of the TransactionOption type.
#using <System.EnterpriseServices.dll> using namespace System; using namespace System::EnterpriseServices; using namespace System::Reflection; // References: // System.EnterpriseServices // An instance of this class will not participate in transactions, but can // share its caller's context even if its caller is configured as // NotSupported, Supported, Required, or RequiresNew. [Transaction(TransactionOption::Disabled)] public ref class TransactionDisabled : public ServicedComponent { }; // An instance of this class will not participate in transactions, and will // share its caller's context only if its caller is also configured as // NotSupported. [Transaction(TransactionOption::NotSupported)] public ref class TransactionNotSupported : public ServicedComponent { }; // An instance of this class will participate in its caller's transaction // if one exists. [Transaction(TransactionOption::Supported)] public ref class TransactionSupported : public ServicedComponent { }; // An instance of this class will participate in its caller's transaction // if one exists. If not, a new transaction will be created for it. [Transaction(TransactionOption::Required)] public ref class TransactionRequired : public ServicedComponent { }; // A new transaction will always be created for an instance of this class. [Transaction(TransactionOption::RequiresNew)] public ref class TransactionRequiresNew : public ServicedComponent { };
