必应广告API C#示例代码无法运行

Question

我尝试运行C#示例代码，但是收到以下错误：

错误代码：InternalError <0>
信息：发生了内部错误。
详细信息：[此处为空白]

我还尝试在自己的代码中实现报告服务，但是在以下行出现了“对象引用未设置为对象实例”的错误：

"Object reference not set to an instance of an object" error on this line:

response = reportingService.SubmitGenerateReport(request);

这是我的代码，已删除id/密码/令牌：

我卡在了如何从API中获取报告的问题上，希望能得到帮助。

更新：听起来很傻，但是传递的活动ID不正确，感谢大家的帮助。

我对这段代码一无所知，但从经验来看，如果您无法运行示例程序，则项目设置很可能存在问题。例如缺少导入或其他问题。 - Jesse Jashinsky

你是正确的，这是一个错误的广告系列ID。 - Greg Burris

Answer 1

你的代码会告诉你为什么会出现这个错误；

private static ReportingServiceClient reportingService = null;
response = reportingService.SubmitGenerateReport(request);

您正在尝试访问一个 null 值的 SubmitGenerateReport 方法。这是不可行的。您应该首先对其进行初始化。

- Soner Gönül

我同意你的观点，但有两个问题：1. 我尝试过初始化它，但是得到了相同的错误；2. 这就是微软在示例代码中的写法：http://msdn.microsoft.com/en-US/library/bb671680.aspx - Greg Burris

@GregBurris 我认为这个例子使用了报告服务或其他什么东西。也许你需要在Visual Studio中增加一些设置选项。 - Soner Gönül

你是正确的，它使用了微软服务。可以在 Visual Studio 中使用“服务引用”将其添加到此地址：https://adcenterapi.microsoft.com/Api/Advertiser/v8/Reporting/ReportingService.svc?wsdl - Greg Burris

感谢Soner的帮助，传递的竞选活动id是不正确的。哎呀！ - Greg Burris

Answer 2

传入了错误的数据。我希望错误信息能够更加详细，而不仅仅是“内部错误”。
