Exemples

L’exemple de code suivant affiche les paramètres de configuration du fournisseur de langage. Les arguments de ligne de commande sont utilisés pour spécifier une langue, une extension de nom de fichier ou un type de fournisseur. Pour l’entrée donnée, l’exemple détermine le fournisseur de langage correspondant et affiche les paramètres du compilateur de langage configurés.

// 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.

Remarques

Utilisez la CompilerInfo classe pour déterminer si une CodeDomProvider implémentation est configurée sur l’ordinateur ou pour examiner les paramètres de configuration et de compilateur d’un fournisseur de langage spécifique.

L’élément< system.codedom> dans le fichier de configuration de l’ordinateur contient les paramètres de configuration du fournisseur de langage et du compilateur. Chaque fournisseur de langage configuré a un élément de configuration du compilateur correspondant. Chaque élément définit le type d’implémentation, les CodeDomProvider noms de langage pris en charge, les extensions de nom de fichier prises en charge et les paramètres du compilateur.

Le .NET Framework définit les paramètres initiaux du compilateur dans le fichier de configuration de l’ordinateur. Les développeurs et les éditeurs de compilateurs peuvent ajouter des paramètres de configuration pour une nouvelle implémentation CodeDomProvider.

La CompilerInfo classe fournit un accès en lecture seule à ces paramètres dans le fichier de configuration de l’ordinateur. Utilisez les GetLanguagesmembres , GetExtensionset CodeDomProviderType pour examiner les attributs de configuration correspondants pour un fournisseur de langage. Utilisez la CreateDefaultCompilerParameters méthode pour obtenir les options du compilateur et les valeurs d’attribut de niveau d’avertissement pour un fournisseur de langage.

Pour plus d’informations sur les paramètres du fournisseur de langage dans le fichier de configuration, consultez Schéma des paramètres du fournisseur de langage et du compilateur.
