Ejemplo

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 Name.

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;

Sample Output:

The variable properties are:

Creation Name =

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

Old name, new name = v, my_new_V_name

Old namespace, new namespace = global, my_new_v_Namespace

Properties count = 12

Qualified Name = my_new_v_Namespace::my_new_V_name

old RaiseEvent, new RaiseEvent = False, True

old read-only, new read-only = False, True

System Variable = False

Type = Int32
