Esempio

L'esempio seguente compila un grafico di origine CodeDOM per un semplice programma Hello World. L'origine viene quindi salvata in un file, compilata in un eseguibile ed eseguita. Il CompileCode metodo illustra come usare la classe per specificare varie impostazioni e opzioni del CompilerParameters compilatore.

Un CompilerParameters oggetto rappresenta le impostazioni e le opzioni per un'interfaccia ICodeCompiler .

Se si compila un programma eseguibile, è necessario impostare la GenerateExecutable proprietà su true. GenerateExecutable Quando è impostato su false, il compilatore genererà una libreria di classi. Per impostazione predefinita, viene inizializzato un nuovo CompilerParameters oggetto con la relativa GenerateExecutable proprietà impostata su false. Se si compila un file eseguibile da un grafo CodeDOM, è necessario definire un oggetto CodeEntryPointMethod nel grafo. Se sono presenti più punti di ingresso del codice, è possibile indicare la classe che definisce il punto di ingresso da usare impostando il nome della classe sulla MainClass proprietà .

È possibile specificare un nome file per l'assembly di output nella OutputAssembly proprietà . In caso contrario, verrà usato un nome di file di output predefinito. Per includere le informazioni di debug in un assembly generato, impostare la IncludeDebugInformation proprietà su true. Se il progetto fa riferimento a qualsiasi assembly, è necessario specificare i nomi degli assembly come elementi di un StringCollection set sulla ReferencedAssemblies proprietà dell'oggetto CompilerParameters utilizzato quando si richiama la compilazione.

È possibile compilare un assembly scritto in memoria anziché su disco impostando la GenerateInMemory proprietà su true. Quando un assembly viene generato nella memoria, il codice può ottenere un riferimento all'assembly generato dalla proprietà CompiledAssembly di un oggetto CompilerResults. Se un assembly viene scritto su disco, è possibile ottenere il percorso dell'assembly generato utilizzando la proprietà PathToAssembly di un CompilerResults.

Per specificare un livello di avviso per l'interruzione della compilazione, impostare la proprietà WarningLevel su un intero che rappresenti il livello di avviso in corrispondenza del quale verrà interrotta la compilazione. È anche possibile configurare il compilatore per interrompere la compilazione se vengono rilevati avvisi impostando la TreatWarningsAsErrors proprietà su true.

Per specificare una stringa di argomenti della riga di comando personalizzati da usare quando si richiama il processo di compilazione, impostare la stringa nella proprietà CompilerOptions. Se è necessario un token di sicurezza Win32 per richiamare il processo di compilazione, specificare il token nella proprietà UserToken. Per includere i file di risorse .NET Framework nell'assembly compilato, aggiungere i nomi dei file di risorse alla EmbeddedResources proprietà . Per fare riferimento alle risorse di .NET Framework in un altro assembly, aggiungere i nomi dei file di risorse alla LinkedResources proprietà . Per includere un file di risorse Win32 nell'assembly compilato, specificare il nome del file di risorse Win32 nella Win32Resource proprietà .
