Examples
The following example creates a package, adds a ForEachLoop, and adds a variable to the Variables collection of the ForEachLoop. It then retrieves and sets properties on the variable and displays them for viewing, including the Description.
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;
