我让插件工作了，我已经在这里更新了工作代码。希望能帮助到你！！

我正在创建一个工作流，它有一个插件来从电子邮件记录的“FROM”字段中检索联系人实体。我正在尝试查看该电子邮件是否存在于联系人实体中。输入是“FROM”电子邮件，输出将返回联系人实体。我无法让这段代码工作，我收到不同的错误或没有错误，但我知道它不起作用。请帮忙！提前致谢！

所以我们正在将我们的内部 CRM 系统从 4.0 升级到 2011，这是一个工作流程中的插件。我没有原始源代码，所以我真的不知道代码在做什么。但是我在导出解决方案后反编译了原始的 .dll 文件。我试图重写 CRM 2011 的代码，这就是我所拥有的。测试工作流程后，我收到错误消息：“预期非空 Guid。” 代码转到循环后的最后一行，然后给我错误。这是跟踪：

我收到不同的错误或没有错误，但我知道它不起作用

首先，我建议您列出问题中的错误。回答您并避免-1会容易得多。:) 其次，在工作流中使用跟踪服务。

ITracingService tracingService = context.GetExtension<ITracingService>();
tracingService.Trace("I'm tracing something....");

如果没有找到指定电子邮件的联系人，应该怎么办？你必须处理这种情况。可能在这里失败了。发布有问题的错误日志，以检查这一点。

如果我要给出一个即时的答案，我想这就是问题所在，在某些情况下你没有得到匹配并过滤掉所有内容。然后，您在某处得到null（或尝试引用一个空的guid，或尝试选择一个尚未输入的属性，这样，虽然它已定义，但未提供服务）。

你得到什么确切的错误？你什么时候得到它们，什么时候没有？

此外，我注意到的代码存在一些问题（不是解决方案，但仍有可能改进）。

名称中的错字。我想你想要ContactReference。

[Output("output")]
[ReferenceTarget("contact")]
public OutArgument<EntityReference> ContactRefernce { get; set; }

我会以不同的方式设计查询。由于您知道要匹配的地址，因此您可能需要精确过滤。此外，您似乎只需要根据电子邮件进行匹配的 guid，因此您只需要获取它。

private Guid MatchSenderWithExistingContact(
  IOrganizationService service, String fromAddress)
{
  QueryExpression query = new QueryExpression
  {
    EntityName = "contact",
    ColumnSet = new ColumnSet("emailaddress1"),
    Criteria = new FilterExpression
    {
      Filters =
      {
        new FilterExpression
        {
          Conditions =
          {
            new ConditionExpression(
              "emailaddress1", ConditionOperator.Equal, fromAddress)
          }
        }
      }
    }
  };

  EntityCollection retrieveMultipleRequest = service.RetrieveMultiple(query);
  IEnumerable<Entity> entities = retrieveMultipleRequest.Entities;
  return entities.FirstOrDefault().Id;
}

您可能希望将查询声明放在逐步语法上。我更喜欢这种方式，因为它在创建高级查询时更方便。但是，如上所示，您迭代和使用break的部分肯定会更好。

快乐编码！

您可能应该使用跟踪。通常，我将跟踪对象声明为插件类中的成员变量，然后在每次操作时写入它。这样，至少我知道粪便在哪里撞击空调，并且可以在此之前记录变量的值。

private ITracingService trace;

public void Execute(IServiceProvider serviceProvider)
{
  trace = (ITracingService)serviceProvider.GetService(typeof(ITracingService));
  _trace.Trace("Tracing successful!");
  throw new Exception("Intentional! Nice.");
}

请记住，除非发生未捕获的异常，否则不会显示跟踪。事实上，我有时故意让执行崩溃，只是为了看看变量中有什么。所以请记住，如果你有一个全局try-catch，你需要手动重新抛出异常。

这种方法的好处是您可以在本地和在线进行跟踪。它适用于除异步之外的所有插件注册。也有解决方法，但这不是你问题的主题，我已经离题了。
