Contoh

Contoh berikut membuat paket, menambahkan ForEachLoop, dan menambahkan variabel ke Variables koleksi ForEachLoop. Kemudian mengambil dan mengatur properti pada variabel dan menampilkannya untuk dilihat, termasuk Description.

static void Main(string[] args)

            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);
