在C＃控制台应用程序中使用Google Ad Manager Api下载/阅读Google Ad Manager报表

Question

我正在尝试阅读/下载我使用Google Ad Manager Api https://developers.google.com/ad-manager/api/reporting在Google Ad Manager帐户中创建的一些报告

但无法获得结果

还尝试了该API的NetworkService和InventoryService服务，以从我的Google广告管理器帐户中抓取一些数据，这些数据可以正常运行，如下所示：

using Google.Api.Ads.AdManager.Lib;
using Google.Api.Ads.AdManager.Util.v201911;
using Google.Api.Ads.AdManager.v201911;
using Google.Api.Ads.Common.Util.Reports;
using System;
using System.IO;
using System.Linq;
using System.Collections.Generic;
using System.Text;
using System.Threading.Tasks;

namespace Google.Api.Ads.AdManager.Examples.CSharp.v201911
{
    /// This example gets all ad units.
    public class GetAllAdUnits : SampleBase
    {
        public string orderId;


        /// Returns a description about the code example.
        public string Description => "This example gets all ad units.";

        /// Main method, to run this code example as a standalone application.
        public static void Main()
        {
            GetAllAdUnits codeExample = new GetAllAdUnits();
            Console.WriteLine(codeExample.Description);
            try
            {
                codeExample.Run(new AdManagerUser());
            }
            catch (Exception e)
            {
                Console.WriteLine("Failed to get ad units. Exception says \"{0}\"", e.Message);
            }

        }

        private string filePath = "/Users/fazeem/";
        /// Run the code example.
        public void Run(AdManagerUser user)
        {
            using (NetworkService networkService = user.GetService<NetworkService>())
            {
                var network = networkService.getCurrentNetwork();
                Console.WriteLine(
                $"Current network has the network code {network.networkCode} and " +
                $"display name \"{network.displayName}\" and Currency {network.currencyCode}."
                );
            }

            using (InventoryService inventoryService = user.GetService<InventoryService>())
            {

                // Create a statement to select ad units.
                int pageSize = StatementBuilder.SUGGESTED_PAGE_LIMIT;
                StatementBuilder statementBuilder1 =
                   new StatementBuilder().OrderBy("id ASC").Limit(pageSize);

                // Retrieve a small amount of ad units at a time, paging through until all
                // ad units have been retrieved.
                int totalResultSetSize = 0;
                do
                {
                    AdUnitPage page =
                        inventoryService.getAdUnitsByStatement(statementBuilder1.ToStatement());

                    // Print out some information for each ad unit.
                    if (page.results != null)
                    {
                        totalResultSetSize = page.totalResultSetSize;
                        int i = page.startIndex;
                        foreach (AdUnit adUnit in page.results)
                        {
                            Console.WriteLine(
                                "{0}) Ad unit with ID \"{1}\" and name \"{2}\" was found.", i++,
                                adUnit.id, adUnit.name);
                        }
                    }

                    statementBuilder1.IncreaseOffsetBy(pageSize);
                } while (statementBuilder1.GetOffset() < totalResultSetSize);

                Console.WriteLine("Number of results found: {0}", totalResultSetSize);
            }


            /////////////////////////////////////////////////////////////////////

            using (ReportService reportService = user.GetService<ReportService>())
            {
                ReportJob reportJob = new ReportJob();
                reportJob.reportQuery = new ReportQuery();
                reportJob.reportQuery.dimensions = new Dimension[]

                };
                reportJob.reportQuery.dimensionAttributes = new DimensionAttribute[]

                reportJob.reportQuery.columns = new Column[]
                {

                reportJob.reportQuery.statement = statementBuilder.ToStatement();



                // Run report job.

                using (ReportResponse reportResponse = reportUtilities.GetResponse())

                Console.WriteLine("Report saved to \"{0}\".", filePath);

            }
}
}
}

但是代码的reportService部分（用于下载/阅读报告）抛出此异常：“无法获取广告单元。异常显示为“ AdManagerApiException：类型为'Google.api.ads.adManager.lib的异常。 adManagerApiException'被抛出”

任何帮助/建议将不胜感激。 TIA

PS我最初是希望直接从Ad Manager帐户中读取一些报告，但找不到有关它的任何详细文档，所以最终请先下载然后再阅读它。因此，如果有人有正确的方法可以直接从中读取报告广告经理帐户，也请分享。
