AWS Glue を使用した例 AWS SDK for .NET

次のコード例は、 AWS SDK for .NET で を使用してアクションを実行し、一般的なシナリオを実装する方法を示しています AWS Glue。

「基本」は、重要なオペレーションをサービス内で実行する方法を示すコード例です。

アクションはより大きなプログラムからのコードの抜粋であり、コンテキスト内で実行する必要があります。アクションは個々のサービス機能を呼び出す方法を示していますが、コンテキスト内のアクションは、関連するシナリオで確認できます。

各例には、完全なソースコードへのリンクが含まれています。ここでは、コンテキストでコードを設定および実行する方法の手順を確認できます。
