TransactionOption Enumeration

Specifies the automatic transaction type requested by the component.

Namespace:  System.EnterpriseServices
Assembly:  System.EnterpriseServices (in System.EnterpriseServices.dll)

[SerializableAttribute]
public enum TransactionOption

Member nameDescription
DisabledIgnores any transaction in the current context.
NotSupportedCreates the component in a context with no governing transaction.
SupportedShares a transaction, if one exists.
RequiredShares a transaction, if one exists, and creates a new transaction if necessary.
RequiresNewCreates the component with a new transaction, regardless of the state of the current context.

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;
using System.EnterpriseServices;
using 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 class TransactionAttribute_TransactionDisabled : 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 class TransactionAttribute_TransactionNotSupported : ServicedComponent
{
}

// An instance of this class will participate in its caller's transaction 
// if one exists.
[Transaction(TransactionOption.Supported)]
public class TransactionAttribute_TransactionSupported : 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 class TransactionAttribute_TransactionRequired : ServicedComponent
{
}

// A new transaction will always be created for an instance of this class.
[Transaction(TransactionOption.RequiresNew)]
public class TransactionAttribute_TransactionRequiresNew : ServicedComponent
{
}
