Beispiele

Im folgenden Beispiel wird entweder der C#- oder Visual Basic-Codeanbieter verwendet, um eine Quelldatei zu kompilieren. Im Beispiel wird die Eingabedateierweiterung überprüft und die entsprechende CSharpCodeProvider oder VBCodeProvider für die Kompilierung verwendet. Die Eingabedatei wird in eine ausführbare Datei kompiliert, und alle Kompilierungsfehler werden in der Konsole angezeigt.
