Örnekler

Aşağıdaki örnek, bir dize döndüren ve Int32türünde bir parametresi olan Function1 adlı bir static yöntemi (Visual Basic'teShared) oluşturur. yönteminin gövdesinde, kod örneği iki yerel değişkeni temsil eden LocalBuilder nesneleri oluşturur ve yerel değişkenler için sembol bilgilerini ayarlar. yöntemi önemli bir şey yapmaz, ancak yöntem gövdesi bir parametreyi yerel değişkene depolamayı, sabit dizeyi yerel bir değişkene depolamayı ve yerel değişkeni yüklemeyi gösterir.
