Hinweise

Eine CodeEntryPointMethod ist eine CodeMemberMethod, die die Einstiegspunktmethode für eine ausführbare Datei darstellt.

Beispiel

In diesem Beispiel wird veranschaulicht, wie mit einer CodeEntryPointMethod die Methode angegeben wird, an der die Programmausführung gestartet werden soll.

' Builds a Hello World Program Graph using System.CodeDom objects
