整体问题是：如何在D365 CRM的插件中访问不在我的馆藏中的实体变量（尚未更新）？
我一直在努力解决这个问题，现在，我转向你们，论坛上帝，帮助理解这里发生的事情。
我在D365 CRM（v9.0）中的工作订单实体上进行了自定义。基本上，每当更新三个字段中的一个时，我每次都需要执行相同的逻辑。无论出于何种原因，只有在一次操作中更新所有三个字段时，插件才会起作用。如果我只更新一个，我将得到＆＃34;密钥不在字典中＃34;错误，表示我的变量不在当前集合中。
我试图改变我的＆＃34;包含＆＃34;检查是否包含XYZ ||包含ABC ||包含123，但立即失败。然后，我试图将每个条件嵌套在彼此中，但当然，最低的巢不会被触及。然后我尝试取消嵌套，然后尝试每个＆＃34;包含＆＃34;单独检查，然后继续执行所有三个块中的逻辑。所有这一切都让我失望了。
我在这里缺少什么吗？出于测试目的，我将它设置为触发所有属性（不仅仅是我想要检查的三个），但即便这样也不适合我。我还与一位同事进行了交谈，他比我在CRM的开发方面拥有更多的经验，你可以在＆＃34; FieldValue＆＃34;中找到一些工件。函数调用（虽然我已从此代码片段中删除了FieldValue函数）。
我是CRM开发的新手，但自4.0以来一直在MSCRM工作 非常感谢任何建议。

如何在D365 CRM的插件中访问不在我的集合中的实体变量（尚未更新）？
答案：图片（预图像或后图像）
在“更新”步骤中注册具有必要属性的图像，这样您将获得整个实体对象或您标记的每个属性。基本上它是一个高效的平台检索调用＆amp;在上下文中为您服务。
例如，在您的情况下，使用PreImage（所有3个属性）注册Post-Update步骤。因此修改后的属性将位于(Entity)context.InputParameters["Target"]中。可以从(Entity)context.PreEntityImages["Image"]使用未修改的属性。 Read more
此外，包含可能始终如此，因此请检查Money / Decimal字段，如解释here。
Money myMoneyField = (Money)EntityObject.GetAttributeValue<Money>(Amount);
decimal actualAmount;
if (myMoneyField != null)
{
actualAmount = myMoneyField.Value;
}
现在你有＆amp;之前的属性值在交易之后，你决定＆amp;存储用于计算的值。
Entity orderEntity = (Entity)context.InputParameters["Target"];
Entity preOrderEntity = (Entity)context.PreEntityImages["Image"];
Decimal preNTEamount = preOrderEntity.GetAttributeValue<Money>("CLIENT_nteamount") != null ? ((Money)preOrderEntity.GetAttributeValue<Money>("CLIENT_nteamount")).Value : 0;
Decimal newNTEamount = orderEntity.GetAttributeValue<Money>("CLIENT_nteamount") != null ? ((Money)orderEntity.GetAttributeValue<Money>("CLIENT_nteamount")).Value : preNTEamount;
