WebMethodAttribute Constructor (Boolean, TransactionOption)
Initializes a new instance of the WebMethodAttribute class.
Assembly: System.Web.Services (in System.Web.Services.dll)
public: WebMethodAttribute( bool enableSession, TransactionOption transactionOption )
Parameters
- enableSession
- Type: System::Boolean
Initializes whether session state is enabled for the XML Web service method.
- transactionOption
- Type: System.EnterpriseServices::TransactionOption
Initializes the transaction support of an XML Web service method.
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)]
