Beispiele

Im folgenden Beispiel wird ein CodeDOM-Quelldiagramm für ein einfaches Hello World-Programm erstellt. Die Quelle wird dann in einer Datei gespeichert, in eine ausführbare Datei kompiliert und ausgeführt. Die CompileCode -Methode veranschaulicht, wie die CompilerParameters -Klasse verwendet wird, um verschiedene Compilereinstellungen und -optionen anzugeben.

Hinweise

Ein CompilerParameters -Objekt stellt die Einstellungen und Optionen für eine ICodeCompiler Schnittstelle dar.

Wenn Sie ein ausführbares Programm kompilieren, müssen Sie die GenerateExecutable -Eigenschaft auf truefestlegen. Wenn auf GenerateExecutable festgelegt falseist, generiert der Compiler eine Klassenbibliothek. Standardmäßig wird eine neue CompilerParameters initialisiert, wobei die GenerateExecutable -Eigenschaft auf falsefestgelegt ist. Wenn Sie eine ausführbare Datei aus einem CodeDOM-Diagramm kompilieren, muss eine CodeEntryPointMethod im Diagramm definiert werden. Wenn mehrere Codeeingabepunkte vorhanden sind, können Sie die Klasse angeben, die den zu verwendenden Einstiegspunkt definiert, indem Sie den Namen der Klasse auf die MainClass -Eigenschaft festlegen.

Sie können einen Dateinamen für die Ausgabeassembly in der OutputAssembly -Eigenschaft angeben. Andererseits wird ein Standardname für die Ausgabedatei verwendet. Um Debuginformationen in eine generierte Assembly einzuschließen, legen Sie die IncludeDebugInformation -Eigenschaft auf fest true. Wenn Ihr Projekt auf Assemblys verweist, müssen Sie die Assemblynamen als Elemente in einem StringCollection Satz für die ReferencedAssemblies Eigenschaft der beim Aufrufen der CompilerParameters Kompilierung verwendeten angeben.

Sie können eine Assembly kompilieren, die in den Arbeitsspeicher und nicht in den Datenträger geschrieben wird, indem Sie die GenerateInMemory -Eigenschaft auf truefestlegen. Wenn eine Assembly im Speicher generiert wird, kann Ihr Code einen Verweis aus einer CompiledAssembly-Eigenschaft einer CompilerResults für die generierte Assembly abrufen. Wenn eine Assembly auf den Datenträger geschrieben wird, können Sie den Pfad zur generierten Assembly aus der PathToAssembly -Eigenschaft eines CompilerResultsabrufen.

Wenn Sie eine Warnstufe angeben möchten, an der Sie die Kompilierung anhalten möchten, legen Sie die WarningLevel-Eigenschaft auf einen Integer fest, der die Warnstufe darstellt, an der die Kompilierung angehalten werden soll. Sie können den Compiler auch so konfigurieren, dass die Kompilierung beendet wird, wenn Warnungen auftreten, indem Sie die TreatWarningsAsErrors -Eigenschaft auf truefestlegen.

Um einen benutzerdefinierte Argumentzeichenfolge auf Befehlszeilenebene anzugeben, die Sie beim Aufruf des Kompilierungsprozesses verwenden, legen Sie die Zeichenfolge in der CompilerOptions-Eigenschaft fest. Wenn ein Win32-Sicherheitstoken erforderlich ist, um den Compilerprozess auszurufen, geben Sie das Token in der UserToken-Eigenschaft an. Um .NET Framework-Ressourcendateien in die kompilierte Assembly einzuschließen, fügen Sie der -Eigenschaft die Namen der Ressourcendateien hinzu EmbeddedResources . Um auf .NET Framework-Ressourcen in einer anderen Assembly zu verweisen, fügen Sie der -Eigenschaft die Namen der Ressourcendateien hinzu LinkedResources . Um eine Win32-Ressourcendatei in die kompilierte Assembly einzuschließen, geben Sie den Namen der Win32-Ressourcendatei in der -Eigenschaft an Win32Resource .
