例

次のコード例では、コンピューター上の言語プロバイダーを列挙し、各言語プロバイダーの構成とコンパイラ設定を表示します。 このコード例は、CompilerInfo クラスのために提供されている大規模な例の一部です。

   CodeDomProvider^ provider = nullptr;
   if ( info )
      provider = info->CreateProvider();

   if ( provider )

      // Display information about this configured provider.
      Console::WriteLine( "Language provider:  {0}", provider->ToString() );
      Console::WriteLine();
      Console::WriteLine( "  Supported file extension(s):" );
