在我的工作流程中，从营销列表中插入或删除联系人。根据输入布尔参数值。 真阳性＆GT;插入 - ＆GT;如果存在联系 然后回来 - ＆GT;其他 假 - ＆gt;去掉 - ＆GT;如果不存在 然后返回
此WFA会在事件发生时运行。
首先它会触发，它运行良好，删除或添加联系人。但我重新运行更改布尔值，我得到以下异常消息：
由于错误导致工作流暂停：未处理的异常： System.NullReferenceException：未将对象引用设置为实例 一个对象。在 ContactToMList.ContactToMList.Execute（CodeActivityContext executionContext）at System.Activities.CodeActivity.InternalExecute（ActivityInstance 实例，ActivityExecutor执行程序，BookmarkManager bookmarkManager） 在 System.Activities.Runtime.ActivityExecutor.ExecuteActivityWorkItem.ExecuteBody（ActivityExecutor
executor，BookmarkManager bookmarkManager，Location resultLocation）
似乎没有采取上下文。

这是我用来与我的Org服务代理进行交互的一些代码。我发现在不通过UI的情况下触发插件很有帮助。它也有助于清理我在开发插件时损坏的数据。
您需要填写自己的域名，用户名，密码和组织名称。注释掉的代码是我用来填充一系列相关实体的东西。如果您需要更多帮助，请告诉我。
