Variable.RaiseChangedEvent Propiedad

Definición

Obtiene o establece un valor booleano que indica si la variable se ha marcado para generar el OnVariableValueChanged(DtsContainer, Variable, Boolean) evento cuando cambia el valor de la variable.

public:
 property bool RaiseChangedEvent { bool get(); void set(bool value); };
[Microsoft.SqlServer.Dts.Runtime.Localization.LocalizablePropertyDescription(typeof(Microsoft.SqlServer.Dts.Runtime.Localized), "RaiseChangedEventDesc")]
public bool RaiseChangedEvent { get; set; }
[<Microsoft.SqlServer.Dts.Runtime.Localization.LocalizablePropertyDescription(typeof(Microsoft.SqlServer.Dts.Runtime.Localized), "RaiseChangedEventDesc")>]
member this.RaiseChangedEvent : bool with get, set
Public Property RaiseChangedEvent As Boolean

Valor de propiedad

Boolean

True si un cambio en el valor de la variable es para generar un OnVariableValueChanged(DtsContainer, Variable, Boolean) evento; en caso contrario, false.

Ejemplos

En el ejemplo siguiente se crea un paquete, ForEachLoop se agrega y se agrega una variable a la Variables colección de ForEachLoop . A continuación, recupera y establece las propiedades de la variable y las muestra para su visualización, incluido RaiseChangedEvent .

static void Main(string[] args)  
        {  
            Package p = new Package();

            Sequence seq = (Sequence)p.Executables.Add("STOCK:SEQUENCE");  
            // Add a ForEachLoop to the Sequence  
            ForEachLoop feLoop = (ForEachLoop)seq.Executables.Add("STOCK:FOREACHLOOP");  

            // Add a variable, v, to the variable collection  
           // of the ForEach loop.  
            Variable v = feLoop.Variables.Add("v", false, "global", 100);  

//  Get and set different variable properties

Salida del ejemplo:

Las propiedades de las variables son:

Nombre de creación =

Descripción = mi nueva descripción de v

ID = {622CF328-55D7-4E81-9385-9C1F8450511E}

Nombre antiguo, nuevo nombre = v, my_new_V_name

Espacio de nombres antiguo, nuevo espacio de nombres = global, my_new_v_Namespace

Recuento de propiedades = 12

Nombre completo = my_new_v_Namespace:: my_new_V_name

Old RaiseEvent, New RaiseEvent = false, true

antiguo de solo lectura, nuevo de solo lectura = false, true

Variable del sistema = false

Tipo = Int32
