dynamics-crm-2011 - 创建案例时更新另一个实体的插件代码 mscrm 2011

Question

我是插件新手。我的问题是，创建案例后，我需要将案例 ID 更新到分类帐中。连接这两者的是 leadid。在我的例子中，我将 lead 重命名为 outbound call。

这是我的代码。我不知道它是否正确。希望你们能帮我解决这个问题，因为它给了我错误。我设法注册它。构建和注册没问题，但是创建案例时，它给我错误。

请检查，

实体是否包含属性。

检查并尝试:

if (targetEntity.Contains("new_outboundcallid"))
((EntityReference)targetEntity["new_outboundcallid"]).Id
