Příklady
Následující příklad kódu zobrazí nastavení konfigurace zprostředkovatele jazyka. Argumenty příkazového řádku slouží k určení jazyka, přípony názvu souboru nebo typu zprostředkovatele. Pro daný vstup příklad určí odpovídajícího zprostředkovatele jazyka a zobrazí nakonfigurované nastavení kompilátoru jazyka.

Poznámky
CompilerInfo Pomocí třídy určete, zda CodeDomProvider je v počítači nakonfigurována implementace, nebo ke kontrole nastavení konfigurace a kompilátoru pro konkrétního zprostředkovatele jazyka.
Element< system.codedom> v konfiguračním souboru počítače obsahuje nastavení konfigurace zprostředkovatele jazyka a kompilátoru. Každý nakonfigurovaný zprostředkovatel jazyka má odpovídající element konfigurace kompilátoru. Každý element definuje CodeDomProvider typ implementace, podporované názvy jazyků, podporované přípony názvů souborů a parametry kompilátoru.
Rozhraní .NET Framework definuje počáteční nastavení kompilátoru v konfiguračním souboru počítače. Vývojáři a dodavatelé kompilátoru můžou přidat nastavení konfigurace pro novou CodeDomProvider implementaci.
Třída CompilerInfo poskytuje přístup jen pro čtení k těmto nastavením v konfiguračním souboru počítače. GetLanguagesPomocí členů , GetExtensionsa CodeDomProviderType zkontrolujte odpovídající atributy konfigurace pro zprostředkovatele jazyka. CreateDefaultCompilerParameters Pomocí metody získejte možnosti kompilátoru a hodnoty atributů úrovně upozornění pro zprostředkovatele jazyka.
Další podrobnosti o nastavení zprostředkovatele jazyka v konfiguračním souboru najdete v tématu Schéma nastavení kompilátoru a zprostředkovatele jazyka.
Poznámka
Tato třída obsahuje požadavek na propojení na úrovni třídy, který se vztahuje na všechny členy. Vyvolá SecurityException se, když bezprostředně volající nemá oprávnění s úplným vztahem důvěryhodnosti. Podrobnosti o požadavcích na propojení najdete v tématu Požadavky na propojení.
