其中一个主键值的类型与实体中定义的类型不匹配。 请参阅内部exception了解详细信

我有以下方法： –

public ActionResult CustomersDetails(string[] SelectRight) { var selectedCustomers = new SelectedCustomers { Info = SelectRight.Select(GetAccount) }; return View(selectedCustomers); } private AccountDefinition GetAccount(string id) { return entities.AccountDefinition.Find(id); } 

但它返回以下错误： –

 The type of one of the primary key values did not match the type defined in the entity. See inner exception for details. 

在return entities.AccountDefinition.Find(id); 线

那么是什么导致了这个错误呢？

内在的例外是： –
