OperationContext.ParameterFactoryMethod Delegate

Exposes to the consumer the right to determine how IDbDataParameter implementations are created.

Syntax

Visual Basic

'Declaration
 
Public Delegate Function OperationContext.ParameterFactoryMethod( _
   ByVal paramName As String, _
   ByVal paramType As DbType, _
   ByVal paramDir As ParameterDirection _
) As IDbDataParameter

C#

public delegate IDbDataParameter OperationContext.ParameterFactoryMethod( 
   string paramName,
   DbType paramType,
   ParameterDirection paramDir
)

Parameters

paramName

paramType

paramDir

Remarks

Ordinarily, the in-scope IDbCommand is used to instantiate database parameters. However, if the application overrides CreateParameter on the WebScheduleDBProvider because their application needs to extend the DataParameterSurrogate then it's necessary to allow the caller to create their own parameters.
