サンプル: Microsoft Dynamics CRM を使用した単純化接続のクイック スタート
公開日: 2016年11月
対象: Dynamics CRM 2015
このサンプルは、CrmConnectionのクラスを使用して Microsoft Dynamics CRM 2015 および Microsoft Dynamics CRM Online 2015 更新プログラム Web サービスに接続し、エンティティで作成、更新、取得、削除など基本的な操作方法を表します。CrmConnection クラスの詳細については、Microsoft Dynamics CRM 2015 の Developer ExtensionsのMicrosoft Dynamics CRM 2015 へのより簡単な接続を参照してください。
要件
完全なサンプル コードは、ダウンロード パッケージの次の場所にあります。
SDK\SampleCode\CS\QuickStart\SimplifiedConnection.cs
Microsoft Dynamics CRM SDK パッケージをダウンロードします。
サンプルを実行する前に、Microsoft Dynamics 365 サーバーのつながり情報で、提供された app.config ファイルを変更する必要があります。 詳細については、Microsoft Dynamics CRM 2015 へのより簡単な接続 と app.config ファイルにコメントしたつながり文字列の例を参照してください。
使用例
このサンプルでは、CrmConnectionクラスおよびメソッドを使って Microsoft Dynamics 365 Web サービスでユーザーを認証します。 組織 Web サービスの参照を取得した後、このサンプルでは取引先企業エンティティで基本作成、更新、取得、削除を実行します。 サンプルでは、一般的な例外も処理します。 ヘルパー コードは、組織 Web サービスへのつながりの確立に使用されません。
例
次はapp.configファイルのサンプルを示します。 これを使用するには、サーバーおよび組織に関連する行の、<add … /> 行の始めにあるコメント文字列 “<!- -” および行の最後にある “- ->” を削除します。 次に、組織に適切な属性値に変更します。
