Exempel

I följande exempel skapas ett CodeDOM-källdiagram för ett enkelt Hello World program. Källan sparas sedan i en fil, kompileras till en körbar fil och körs. Metoden CompileCode visar hur du använder CompilerParameters klassen för att ange olika kompilatorinställningar och alternativ.

Kommentarer

Ett CompilerParameters objekt representerar inställningarna och alternativen för ett ICodeCompiler gränssnitt.

Om du kompilerar ett körbart program måste du ange GenerateExecutable egenskapen till true. När GenerateExecutable är inställt på false, genererar kompilatorn ett klassbibliotek. Som standard initieras en ny CompilerParameters med dess GenerateExecutable egenskap inställd på false. Om du kompilerar en körbar fil från en CodeDOM-graf måste en CodeEntryPointMethod definieras i diagrammet. Om det finns flera kodinmatningspunkter kan du ange den klass som definierar startpunkten som ska användas genom att ange namnet på klassen till MainClass egenskapen.

Du kan ange ett filnamn för utdatasammansättningen i egenskapen OutputAssembly . Annars används ett standardnamn för utdatafilen. Om du vill inkludera felsökningsinformation i en genererad sammansättning anger du IncludeDebugInformation egenskapen till true. Om projektet refererar till några sammansättningar måste du ange sammansättningsnamnen som objekt i en StringCollection uppsättning till egenskapen för den ReferencedAssembliesCompilerParameters som används vid anrop av kompilering.

Du kan kompilera en sammansättning som skrivs till minnet i stället för disken genom att ställa in GenerateInMemory egenskapen på true. När en sammansättning genereras i minnet kan koden hämta en referens till den genererade sammansättningen från CompiledAssembly egenskapen för en CompilerResults. Om en sammansättning skrivs till disken kan du hämta sökvägen till den genererade sammansättningen från PathToAssembly egenskapen för en CompilerResults.

Om du vill ange en varningsnivå där kompilering ska stoppas anger du WarningLevel egenskapen till ett heltal som representerar varningsnivån där kompilering ska stoppas. Du kan också konfigurera kompilatorn att stoppa kompilering om varningar påträffas genom att ange TreatWarningsAsErrors egenskapen till true.

Om du vill ange en anpassad kommandoradsargumentsträng som ska användas när kompileringsprocessen anropas anger du strängen CompilerOptions i egenskapen . Om en Win32-säkerhetstoken krävs för att anropa kompileringsprocessen anger du token i UserToken egenskapen. Om du vill inkludera .NET Framework-resursfiler i den kompilerade sammansättningen lägger du till namnen på resursfilerna i egenskapen EmbeddedResources. Om du vill referera till .NET Framework-resurser i en annan sammansättning lägger du till namnen på resursfilerna i egenskapen LinkedResources. Om du vill inkludera en Win32-resursfil i den kompilerade sammansättningen anger du namnet på Win32-resursfilen i Win32Resource egenskapen.
