Dynamics 365 CRM Online - 使用不在集合中的字段（尚未更新）

Question

总体问题是：如何在 D365 CRM 的插件中访问不在我的集合中（尚未更新）的实体变量？

我已经为此纠结了很长一段时间，现在，我向论坛大神们求助，以了解这里发生的事情。

我在 D365 CRM (v9.0) 中对工单实体进行了自定义。本质上，无论何时更新三个字段中的一个，我每次都需要执行相同的逻辑。无论出于何种原因，该插件仅在所有三个字段都在一次操作中更新时才能工作。如果我只更新一个，我会收到 "key not present in dictionary" 错误，表示我的变量不在当前集合中。

我试图将我的 "contains" 检查更改为包含 XYZ ||包含 ABC ||包含 123，但立即失败。然后，我尝试将每个条件相互嵌套，但当然，最低的嵌套不会被触及。然后我尝试取消嵌套，然后单独尝试每个 "contains" 检查，然后继续执行所有三个 if 块中的逻辑。所有这一切都让我失望了。

这里有我遗漏的东西吗？出于测试目的，我将其设置为触发所有属性（不仅仅是我想检查的三个属性），但即使这样对我来说也失败了。我还与一位在 CRM 开发方面经验比我丰富得多的同事交谈过，你可以在 "FieldValue" 函数调用中看到一些工件（尽管我已经去掉了此代码片段中的 FieldValue 函数）。

我是 CRM 开发的新手，但从 4.0 开始就开始使用 MSCRM。
非常感谢任何建议。

Answer 1

How do I access entity variables that are not in my collection (haven't been updated) in a plugin for D365 CRM?

答案：图片（预图片或Post-图片）

在Update步骤注册一个带有必要属性的Image，这样你会得到整个实体对象或者你标记的每一个属性。基本上它是一个高效的平台检索调用，并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-更新步骤。所以修改后的属性会在(Entity)context.InputParameters["Target"]中。可以从 (Entity)context.PreEntityImages["Image"] 使用未修改的属性。 Read more

Also Contains 可能总是如此，因此请检查 Money/Decimal 字段，如所述。

Money myMoneyField = (Money)EntityObject.GetAttributeValue<Money>(Amount);

decimal actualAmount;

if (myMoneyField != null)
{
    actualAmount = myMoneyField.Value;
}

现在您拥有交易前后的属性值，因此您决定并存储要在计算中使用的值。

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;
