逐步解說：C 中的 Bing 廣告 API 傳統型應用程式#

發行項
05/29/2024

此範例 C# 控制台應用程式會透過您提供的認證提示使用者同意，然後取得已驗證使用者可以存取的帳戶。

您必須先註冊應用程式，並記下用戶端標識碼 (已註冊的應用程式識別碼) 。如需註冊應用程式和授權碼授與流程的詳細資訊，請參閱使用 OAuth 進行驗證。

您也需要生產開發人員令牌。您可以依照下面所述逐步建立範例，或從 GitHub 下載更多範例。

程式碼逐步解說

開啟 Visual Studio 開發環境。
透過檔案 -New ->>Project 建立新專案
在 [ 新增專案] 視窗的下拉式清單中選擇 [.NET Framework 4.8 ]，然後按兩下 [控制台應用程式] (.NET [Framework) ] 範本。將專案命名為 BingAdsConsoleApp ，然後按兩下 [ 確定]。
透過 NuGet 為 BingAdsConsoleApp 安裝 SDK。如需相依性的詳細資訊，請參閱安裝 SDK。按兩下 [工具->NuGet 套件管理員 ->套件管理員主控台]。在提示字元中，輸入下列命令，一次安裝一個套件：和 Install-Package System.Configuration.ConfigurationManagerInstall-Package Microsoft.BingAds.SDK

開啟 App.config 檔案，並以下列程式代碼區塊取代其內容。編輯 BingAdsEnvironment 以從沙箱移至生產環境。如果您的目標是生產環境，則必須將 4c0b021c-00c3-4508-838f-d3127e8167ff 取代為註冊生產應用程式時所布建的應用程式標識符，並將BBD37VB98取代為生產開發人員令牌。

建立配置檔案。在 BingAdsConsoleApp 的項目檢視中，以滑鼠右鍵按兩下 [ 屬性] ，然後按兩下 [ 開啟]。按兩下 [ 設定]，然後按下文字 [專案不包含預設配置檔案]。按兩下這裡建立一個。系統會自動新增來自 app.config 的新值。

<add key="BingAdsEnvironment" value ="Sandbox"/>

您也可以個別設定每個 ServiceClient 的環境，如下所示。

_customerManagementService = new ServiceClient<ICustomerManagementService>(
    _authorizationData, 
    ApiEnvironment.Sandbox
);

無論您是全域或個別設定 ServiceClient 環境，您也必須將 OAuth 環境設定為沙箱。

var oAuthDesktopMobileAuthCodeGrant = new OAuthDesktopMobileAuthCodeGrant(
    ClientId, 
    ApiEnvironment.Sandbox
);
