Příklady

Následující příklad sestaví zdrojový graf CodeDOM pro jednoduchý program Hello World. Zdroj se pak uloží do souboru, zkompiluje se do spustitelného souboru a spustí se. Metoda CompileCode ukazuje, jak použít CompilerParameters třídu k určení různých nastavení a možností kompilátoru.

Poznámky

Objekt CompilerParameters představuje nastavení a možnosti rozhraní ICodeCompiler .

Pokud kompilujete spustitelný program, musíte vlastnost nastavit GenerateExecutable na true. Pokud je nastavena GenerateExecutable na false, kompilátor vygeneruje knihovnu tříd. Ve výchozím nastavení se inicializuje nový CompilerParameters s jeho GenerateExecutable vlastností nastavenou na false. Pokud kompilujete spustitelný soubor z grafu CodeDOM, CodeEntryPointMethod musí být v grafu definován. Pokud existuje více vstupních bodů kódu, můžete označit třídu, která definuje vstupní bod, který se má použít nastavením názvu třídy na MainClass vlastnost.

Ve vlastnosti můžete zadat název souboru pro výstupní sestavení OutputAssembly . V opačném případě se použije výchozí název výstupního souboru. Chcete-li zahrnout informace o ladění do vygenerovaného sestavení, nastavte IncludeDebugInformation vlastnost na true. Pokud váš projekt odkazuje na nějaká sestavení, je nutné zadat názvy sestavení jako položky v StringCollection sadě na ReferencedAssemblies vlastnost CompilerParameters použité při vyvolání kompilace.

Sestavení, které je zapsáno do paměti místo disku, můžete zkompilovat nastavením GenerateInMemory vlastnosti na true. Při generování sestavení v paměti může kód získat odkaz na vygenerované sestavení z CompiledAssembly vlastnosti CompilerResults. Pokud je sestavení zapsáno na disk, můžete získat cestu k vygenerovanému sestavení z PathToAssembly vlastnosti CompilerResults.

Pokud chcete určit úroveň upozornění, na které chcete zastavit kompilaci, nastavte WarningLevel vlastnost na celé číslo, které představuje úroveň upozornění, na které chcete zastavit kompilaci. Můžete také nakonfigurovat kompilátor tak, aby zastavil kompilaci v případě, že se objeví upozornění, nastavením TreatWarningsAsErrors vlastnosti na true.

Pokud chcete zadat vlastní řetězec argumentů příkazového řádku, který se má použít při vyvolání procesu kompilace, nastavte řetězec ve CompilerOptions vlastnosti . Pokud se k vyvolání procesu kompilátoru vyžaduje token zabezpečení Win32, zadejte token ve UserToken vlastnosti . Chcete-li zahrnout soubory prostředků rozhraní .NET Framework do kompilovaného sestavení, přidejte do EmbeddedResources vlastnosti názvy souborů prostředků. Chcete-li odkazovat na prostředky rozhraní .NET Framework v jiném sestavení, přidejte do LinkedResources vlastnosti názvy souborů prostředků. Chcete-li zahrnout soubor prostředku Win32 do kompilovaného sestavení, zadejte název souboru prostředku Win32 ve Win32Resource vlastnosti.
