範例
下列程式代碼範例會顯示語言提供者組態設定。 命令行自變數可用來指定語言、擴展名或提供者類型。 針對指定的輸入，此範例會決定對應的語言提供者，並顯示已設定的語言編譯程序設定。

備註
使用 類別 CompilerInfo 來判斷計算機上是否已 CodeDomProvider 設定實作，或檢查特定語言提供者的組態和編譯程序設定。
計算機組態檔中的 system.codedom> 元素包含語言提供者和編譯程式組態設定。< 每個設定的語言提供者都有對應的編譯程式組態專案。 每個元素都會 CodeDomProvider 定義實作類型、支援的語言名稱、支援的擴展名，以及編譯程序參數。
.NET Framework 會在計算機組態檔中定義初始編譯程式設定。 開發人員和編譯器廠商可以為新的 CodeDomProvider 實作新增組態設定。
類別 CompilerInfo 提供計算機組態檔中這些設定的唯讀存取權。 GetLanguages使用、 GetExtensions和 CodeDomProviderType 成員來檢查語言提供者的對應組態屬性。 CreateDefaultCompilerParameters使用方法來取得語言提供者的編譯程式選項和警告層級屬性值。
如需組態檔中語言提供者設定的詳細資訊，請參閱 編譯程式和語言提供者設定架構。
注意
此類別包含套用至所有成員之類別層級的連結需求。 SecurityException當立即呼叫端沒有完全信任權限時，會擲回 。 如需連結需求的詳細資訊，請參閱 連結需求。
