如何获取实体属性元数据列表？

Question

Dynamics 365 v8.2.2.

为什么 attributesMetadata 是 null？如何获取实体属性元数据列表？

{
    var req = new RetrieveEntityRequest {
        LogicalName = "opportunity",
        RetrieveAsIfPublished = true,
    };

    var resp = srv.Execute(req) as RetrieveEntityResponse;
    var entityMetadata = resp.EntityMetadata;
    var attributesMetadata = entityMetadata.Attributes; // null
}

Answer 1

您需要在请求中设置 EntityFilters，例如：

EntityFilters = EntityFilters.All

或

EntityFilters = EntityFilters.Attributes

完整代码片段如下：

RetrieveEntityRequest retrieveEntityRequest = new RetrieveEntityRequest
{
    EntityFilters = EntityFilters.Attributes,
    LogicalName = "opportunity"
};
RetrieveEntityResponse retrieveOpptyEntityResponse(RetrieveEntityResponse)service.Execute(retrieveEntityRequest);
EntityMetadata opptyEntity = retrieveOpptyEntityResponse.EntityMetadata;

默认情况下，EntityFilters.Default只会检索实体信息，这就是为什么您的属性列表为空。
