在你提供的代码中，参数 `model` 是通过方法 `UpdateBlockTime` 接收的。如果你说无法获取到参数，可能是因为参数 `model` 的值没有正确传递给该方法。请确保在调用 `UpdateBlockTime` 方法时，传递了有效的 `IPS_Invoice` 对象作为参数。例如，你可以使用类似以下的代码进行调用： ```csharp IPS_Invoice invoice = new IPS_Invoice(); // 设置 invoice 的属性值 string result = UpdateBlockTime(invoice); ``` 另外，在你的代码中，你在更新 `iPS_Invoice` 对象后并调用了 `iPSContext.SaveChanges()` 方法保存更改。如果你说无法获取到参数，可能是因为在保存更改之前，`model` 参数的值并没有正确传递给 `GetWorkQueueDetail` 方法。请确保在调用 `GetWorkQueueDetail` 方法之前，`model` 参数的值已经正确设置。如果上述方法仍然无法解决问题，请提供更多相关的代码或上下文信息，以便我能够更好地帮助你解决问题。
