O exemplo seguinte constrói um grafo-fonte CodeDOM para um programa simples do Hello World. A fonte é então guardada num ficheiro, compilada num executável e executada. O CompileCode método ilustra como usar a CompilerParameters classe para especificar várias definições e opções do compilador.

Observações

Um CompilerParameters objeto representa as definições e opções para uma ICodeCompiler interface.

Se você estiver compilando um programa executável, você deve definir a GenerateExecutable propriedade como true. Quando o GenerateExecutable estiver definido como false, o compilador gerará uma biblioteca de classes. Por padrão, um novo CompilerParameters é inicializado com sua GenerateExecutable propriedade definida como false. Se você estiver compilando um executável a partir de um gráfico CodeDOM, um CodeEntryPointMethod deve ser definido no gráfico. Se existirem múltiplos pontos de entrada de código, pode indicar a classe que define o ponto de entrada a usar, definindo o nome da classe para a MainClass propriedade.

Pode especificar um nome de ficheiro para o conjunto de saída na OutputAssembly propriedade. Caso contrário, um nome de arquivo de saída padrão será usado. Para incluir informação de depuração numa assembly gerada, defina a IncludeDebugInformation propriedade para true. Se o seu projeto referenciar algum assembly, deve especificar os nomes de assembly como itens num StringCollection conjunto à ReferencedAssemblies propriedade do CompilerParameters usado ao invocar a compilação.

Você pode compilar um assembly que é gravado na memória em vez de no disco definindo a propriedade GenerateInMemory para true. Quando um assembly é gerado na memória, o seu código pode obter uma referência ao assembly gerado da propriedade de CompiledAssembly. Se um assembly for gravado no disco, poderá obter o caminho para o assembly gerado da propriedade de um PathToAssembly.

Para especificar um nível de aviso no qual interromper a compilação, defina a WarningLevel propriedade como um inteiro que representa o nível de aviso no qual a compilação deve ser interrompida. Você também pode configurar o compilador para interromper a compilação se forem encontrados avisos definindo a TreatWarningsAsErrors propriedade como true.

Para especificar argumentos de linha de comando personalizados a serem usados ao invocar o processo de compilação, defina o valor da propriedade para CompilerOptions. Se um token de segurança Win32 for necessário para invocar o processo do compilador, especifique o token UserToken na propriedade. Para incluir .NET ficheiros de recurso do Framework na assembly compilada, adicione os nomes dos ficheiros de recurso à propriedade EmbeddedResources. Para referenciar .NET recursos do Framework noutra assembleia, adicione os nomes dos ficheiros de recursos à propriedade LinkedResources. Para incluir um ficheiro de recurso Win32 na assembly compilada, especifique o nome do ficheiro de recurso Win32 na Win32Resource propriedade.
