クラスを CompilerInfo 使用して、実装がコンピューターで構成されているかどうかを CodeDomProvider 判断するか、特定の言語プロバイダーの構成とコンパイラ設定を調べます。

マシン構成ファイルの system.codedom> 要素には、言語プロバイダーとコンパイラ構成設定が含まれています。< 構成された各言語プロバイダーには、対応するコンパイラ構成要素があります。 各要素は、実装の CodeDomProvider 種類、サポートされている言語名、サポートされているファイル名拡張子、コンパイラ パラメーターを定義します。

.NET Frameworkは、マシン構成ファイルの初期コンパイラ設定を定義します。 開発者やコンパイラ ベンダーは、新しい CodeDomProvider の実装のために構成設定を追加することができます。

クラスは CompilerInfo 、マシン構成ファイル内のこれらの設定への読み取り専用アクセスを提供します。 、、および CodeDomProviderType メンバーをGetLanguagesGetExtensions使用して、言語プロバイダーの対応する構成属性を調べます。 言語プロバイダーの CreateDefaultCompilerParameters コンパイラ オプションと警告レベルの属性値を取得するには、 メソッドを使用します。

構成ファイルの言語プロバイダー設定の詳細については、「 コンパイラと言語プロバイダーの設定スキーマ」を参照してください。
