CompilerInfo
Exemplos
O exemplo de código a seguir exibe as configurações do provedor de idiomas. Os argumentos de linha de comando são usados para especificar um idioma, uma extensão de nome de arquivo ou um tipo de provedor. Para a entrada fornecida, o exemplo determina o provedor de idioma correspondente e exibe as configurações do compilador de linguagem definidas.
// Command-line argument examples:
// - Displays Visual Basic, C#, and JScript compiler settings.
// <exe_name> Language CSharp
// - Displays the compiler settings for C#.
// <exe_name> All
// - Displays settings for all configured compilers.
// <exe_name> Config Pascal
// - Displays settings for configured Pascal language provider,
// if one exists.
// <exe_name> Extension .vb
// - Displays settings for the compiler associated with the .vb
// file extension.

Comentários
Use a CompilerInfo classe para determinar se uma CodeDomProvider implementação está configurada no computador ou para examinar as configurações e as configurações do compilador para um provedor de idioma específico.
O <elemento system.codedom> no arquivo de configuração do computador contém as configurações do provedor de idiomas e do compilador. Cada provedor de idioma configurado tem um elemento de configuração do compilador correspondente. Cada elemento define o CodeDomProvider tipo de implementação, nomes de linguagem com suporte, extensões de nome de arquivo com suporte e parâmetros do compilador.
O .NET Framework define as configurações iniciais do compilador no arquivo de configuração do computador. Os desenvolvedores e fornecedores do compilador podem adicionar parâmetros de configuração em uma nova implementação do CodeDomProvider.
A CompilerInfo classe fornece acesso somente leitura a essas configurações no arquivo de configuração do computador. Use os GetLanguagesmembros , GetExtensionse CodeDomProviderType para examinar os atributos de configuração correspondentes de um provedor de idiomas. Use o CreateDefaultCompilerParameters método para obter as opções do compilador e os valores de atributo de nível de aviso para um provedor de idiomas.
Para obter mais detalhes sobre as configurações do provedor de idiomas no arquivo de configuração, consulte Esquema de configurações do compilador e do provedor de idiomas.
Observação
Essa classe contém uma demanda de link no nível de classe que se aplica a todos os membros. Um SecurityException é gerado quando o chamador imediato não tem permissão de confiança total. Para obter detalhes sobre as demandas de link, consulte Vincular demandas.
