给定的密​​钥不在字典Microsoft CRM插件中

Question

另一个Microsoft CRM插件相关问题。我的插件在更新发票记录时触发。我想将一些发票字段的内容复制到佣金记录中的相应字段。包含截止日期的if似乎工作正常，但包含invoiceamount的if表示密钥不存在错误。我已检查所有字段名称是否正确并存在于正确的实体中。

任何想法发生了什么？我是否需要使用图片？如果是的话，有人可以帮我一些代码吗？

在更新中，您将只获得更新字段的值。目标实体中不存在其他字段。您需要使用PreImage注册插件。将字段添加到要在插件中访问的PreImage。

preImage = (Entity)context.PreEntityImages["PreImage"];
