Ejemplos
En el ejemplo siguiente se crea un paquete, se agrega un ForEachLoopy se agrega una variable a la Variables colección de ForEachLoop. A continuación, recupera y establece propiedades en la variable y las muestra para su visualización, incluido .Namespace
static void Main(string[] args)
{
Package p = new Package();
// Add a sequence to the package executables collection
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
// Creation Name (read-only)
String createName = v.CreationName;
// Description (read/write)
v.Description = "my new v Description";
String vDesc = v.Description;
// ID (read-only)
String vID = v.ID;
// Name (read/write)
String oldName = v.Name;
v.Name = "my_new_V_name";
String newName = v.Name;
// Namespace (read/write)
String oldNamespace = v.Namespace;
v.Namespace = "my_new_v_Namespace";
String newNamespace = v.Namespace;
// Properties (read-only)
int pmCount = v.Properties.Count;
// Qualified Name (read-only)
String QName = v.QualifiedName;
// RaiseChangedEvent (read/write)
Boolean oldraiseChEvt = v.RaiseChangedEvent;
v.RaiseChangedEvent = true;
Boolean raiseChangedEvent = v.RaiseChangedEvent;
// Read-only (read/write)
Boolean vReadOnly = v.ReadOnly;
v.ReadOnly = true;
Boolean newVReadOnly = v.ReadOnly;
// System Variable (read-only)
Boolean sysVar = v.SystemVariable;
// Type (read-only)
TypeCode type = v.DataType;
// Value (read/write)
Object vValue = v.Value;

Salida del ejemplo:
Las propiedades de la variable son:
Nombre de creación =
Descripción = mi nueva descripción v
Id. = {622CF328-55D7-4E81-9385-9C1F8450511E}
Nombre anterior, 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
old read-only, new read-only = False, True
Variable del sistema = False
Type = Int32
Comentarios
Puede cambiar el espacio de nombres de las variables, excepto las System
variables creadas por el tiempo de ejecución para un paquete. Estas variables deben permanecer en el System
espacio de nombres.
