我应该如何知道Dynamics crm插件中基于消息请求的InputParameters下的哪个属性？

CreateRequest消息被命名为Target，其类型为Entity。但是并非所有Request都包含Target属性的类型为Entity。

CreateRequest Message is named Target,which is of type Entity.But not all Request contain a Target property is of type Entity.

例如，AssociateRequest InputParameter包含Relationship为

For Example AssociateRequest InputParameter contains Relationship is of type Relationship.

例如，AddItem消息将返回哪个属性？我应该如何知道插件注册工具中有这么多消息？我应该如何知道哪个消息有什么

For Example AddItem message will return which property?How should I know there are so many messages in plugin registration tool.how should I know which message has what property it will return.

只能通过调试来实现吗？

it was only possible with Debugging?
