c# - 带有脚本组件和服务引用的 SSIS

Question

我正在尝试通过 SSIS 获取 BingAds 数据以存储在我们的会计系统中。我添加了对 https://api.sandbox.bingads.microsoft.com/Api/Advertiser/v8/CampaignManagement/CampaignManagementService.svc?wsdl 的服务引用用于测试。

我直接从 http://msdn.microsoft.com/en-us/library/adcenter-campaign-management-csharp-samples-get-campaigns.aspx 复制了 GetCampaigns 代码，并稍作修改，因为这不是控制台应用程序。

当我运行我的脚本组件时，我收到以下消息:

Message
Could not find default endpoint element that references contract
'BingAds.CampaignManagementService.ICampaignManagementService' in the ServiceModel
client configuration section. This might be because no configuration file was
found for your application, or because no endpoint element matching this contract
could be found in the client element.

我的 app.config 看起来应该包含所需的一切。我错过了什么吗？

我的 app.config 如下:

<?xml version="1.0" encoding="utf-8" ?>

Answer 1

.NET 在加载配置数据时查找的配置文件是实际运行的可执行文件的配置文件；将 app.config 添加到 SSIS 脚本组件的项目不会生成 SSIS 知道要查找的配置文件。根据您选择运行程序包的方式，它将寻找 BIDS、SQL Server 或 dtexec 的配置文件。

在代码中构建端点并完全绕过配置文件会更好。如果您的大多数配置选项都是默认值，那么它甚至没有那么复杂，因为您只需要设置更改的属性。

这个 Stack Overflow 问题应该告诉你如何去做:
