Comentarios

Esta implementación de OleDbDataAdapter se abre y cierra si OleDbConnection aún no está abierta. Esto puede ser útil en una aplicación que debe llamar al Fill método para dos o más OleDbDataAdapter objetos. Si ya OleDbConnection está abierto, debe llamar Close explícitamente a o Dispose para cerrarlo.

Esta sobrecarga del OleDbDataAdapter constructor usa el selectConnectionString parámetro para establecer la SelectCommand propiedad . Sin embargo, no abre la conexión. Todavía debe abrir explícitamente la conexión.

Propiedades	Valor inicial
MissingMappingAction	`MissingMappingAction.Passthrough`
MissingSchemaAction	`MissingSchemaAction.Add`

Puede cambiar el valor de cualquiera de estas propiedades a través de una llamada independiente a la propiedad .
