C# のコード例: ゲーム オプションおよびトレーラーを含むアプリの申請

この記事では、次のタスクに Microsoft Store 申請 API を使用する方法を示す C# コード例を示します。

  • Microsoft Store 申請 API で使用する Azure AD アクセス トークンを取得します。
  • アプリの申請の作成
  • ゲームトレーラーの高度な登録情報のオプションを含む、アプリの申請用のストア登録情報データを構成します。
  • アプリの申請用のパッケージ、登録情報の画像、トレーラー ファイルが含まれた ZIP ファイルをアップロードします。
  • アプリの申請をコミットします。

各例を確認して、それぞれが対応するタスクについて詳しく知ることができます。また、この記事のすべてのコード例を使って、コンソール アプリケーションをビルドすることもできます。 例をビルドするには、Visual Studio で DevCenterApiSample という名前の C# コンソール アプリケーションを作成し、各例をプロジェクト内の別のコード ファイルにコピーして、プロジェクトをビルドします。

前提条件

これらの例には、次の要件があります。

  • プロジェクト内の System.Web アセンブリへの参照を追加します。
  • Newtonsoft からプロジェクトに Newtonsoft.Json NuGet パッケージをインストールします。

アプリの申請の作成

CreateAndSubmitSubmissionExample クラスは、他のサンプル メソッドを呼び出して Microsoft Store 申請 API を使用して、ゲーム オプションとトレーラーを含むアプリの申請を作成およびコミットするパブリック Execute メソッドを定義します。 このコードを採用するには、次の手順を実行してください。
