WebMethodAttribute Constructor (Boolean, TransactionOption, Int32, Boolean)

Initializes a new instance of the WebMethodAttribute class.

Namespace:  System.Web.Services
Assembly:  System.Web.Services (in System.Web.Services.dll)

public:
WebMethodAttribute(
	bool enableSession, 
	TransactionOption transactionOption, 
	int cacheDuration, 
	bool bufferResponse
)

Parameters

enableSession
Type: System::Boolean

Initializes whether session state is enabled for the XML Web service method.

transactionOption
Type: System.EnterpriseServices::TransactionOption

cacheDuration
Type: System::Int32

Initializes the number of seconds the response is cached.

bufferResponse
Type: System::Boolean

Initializes whether the response for this request is buffered.

A web service call can only be the root of a transaction, due to the stateless nature of the HTTP protocol. This means that the following two settings are equivalent, with each call creating a new transaction:

[WebMethod(TransactionOption = TransactionOption.Required)]
[WebMethod(TransactionOption = TransactionOption.RequiresNew)]

It also means that all the following settings are equivalent; meaning no transaction support:

[WebMethod] // TransactionOption.Disabled is the default
[WebMethod(TransactionOption = TransactionOption.Disabled)]
[WebMethod(TransactionOption = Transaction.NotSupported)]
[WebMethod(TransactionOption = Transaction.Supported)]
