C# 在输出参数CRM中返回EntityCollection时出错

我在Dynamics CRM中创建自定义操作，并添加输入和输出参数，因此情况是，当发送输入时，它将过滤具有该属性的某个实体，并在输出参数中返回实体集合。但问题是它总是返回错误，状态为500 Internal Server error，这是我收到的完整错误

假设我有一个名为“Result2”的输出参数。 以下是将输出参数发送到自定义操作的代码-

 context.OutputParameters["Result2"] = new EntityCollection(new List<Entity> { entitlements.FirstOrDefault(), order}); //entitlements is List<Entity> object, order is Entity object

---

public void Execute（IServiceProvider服务提供者）
{
ITracingService tracer=（ITracingService）serviceProvider.GetService（typeof（ITracingService））；
IPluginExecutionContext上下文=（IPluginExecutionContext）serviceProvider.GetService（类型为（IPluginExecutionContext））；
IOOrganizationServiceFactory工厂=（IOOrganizationServiceFactory）服务提供者.GetService（类型（IOOrganizationServiceFactory））；
IOOrganizationService=factory.CreateOrganizationService（context.UserId）；
尝试
{
实体=空；
if（context.InputParameters.Contains（“TargetOrder”））
{
if（context.InputParameters[“TargetOrder”]是实体）
实体=（实体）上下文.InputParameters[“TargetOrder”]；
else if（context.InputParameters[“TargetOrder”]是EntityReference）
{
EntityReference entityRef=（EntityReference）上下文。InputParameters[“TargetOrder”]；
entity=service.Retrieve（entityRef.LogicalName，entityRef.Id，新的Microsoft.Xrm.Sdk.Query.ColumnSet（true））；
}
}
OutputParameters[“Result2”]=新的EntityCollection（新列表{entity}）；
}

希望能有所帮助。

可能重复的我认为它不同，因为我正在使用Action并引用此链接，我可以这样做，我不知道哪一个是正确的，或者Action和自定义工作流活动都不能返回EntityCollection？您好，谢谢您的回答，但您能确认它也可以与EntityCollection一起使用吗？因为我nt将在我的输出参数中返回实体列表。当我将输出类型更改为实体集合时，我无法选择我的实体是的，它也适用于EntityCollection。我已经更新了帖子。嗨，我已经按照你的建议进行了操作，但仍然收到相同的错误消息，请告诉我你的完整代码，以便我可以使用我的代码进行查看，我已经在我的回答中添加了我的代码和操作设置。我正在用PostmanUpdated帖子测试我的操作。我还没有在Postman上检查它。添加了用于调用操作的脚本。我已经使用Process.js库来调用此操作。这是下载Process.js的链接-实际上，你能给我操作代码吗？我想知道，也许我我的代码中遗漏了一些东西
