C#实体框架：临时返回空值的存储过程

我们试图使用一个实体通过存储过程写入我们的数据库，它正在工作，但是，存储过程也有一个输出来返回它刚刚插入的行的ID。我忽略了初始化所有传递的值，但我们的问题存在于以下代码中：

 ObjectParameter output = new ObjectParameter("cUSTOMER_ID", typeof(int));
 var test = database.ADD_CUSTOMER_JSON(companyID, customerName, firstName, lastName, address_1, address_2, cityID, stateID, zipID, primaryPhoneNumber, alternatePhoneNumber, secondaryPhoneNumber, emailAddress, customerNotes, modifiedBy, output);

 if(QuickBooksController.getTokens(companyID).Length > 0)
 {
      QuickBookCustomerQuery customer = GetCustomerDetailsForQuickBooks((int)output.Value);
      QuickBooksController.CreateCustomer(companyID, customer, (int)output.Value);
 }

当我们运行此代码时，我们得到一个错误，

output.value

为空：

System.NullReferenceException:“对象引用未设置为对象的实例。”
System.Data.Entity.CoreObjects.ObjectParameter.Value.get返回空值

我们在那里有一个断点，如果我们检查

output

的值，我们会看到它为null，但是如果我们等待几秒钟并检查它，那么它就有了值，并且数据会写入数据库。如果我们在那之后继续执行代码，那么它就工作了。我认为

If

中的代码会被阻塞，直到SP完成并返回其值。我们在应用程序的其他地方使用完全相同的代码，没有问题。唯一的区别是

var测试=…

之后会发生什么，有什么建议或想法吗？我们都被这件事难住了
