问题描述

嘿！

我正在建立某种客户管理计划，目前正在搁浅。我有两个表，"客户"和"联系人"。在我的WinForm中，我有2个文本框和1个组合框。文本框将分别具有表联系人
的值Name和FirstName，组合框从customers表中选择1个客户，我需要将该客户的ID插入到联系人中。最聪明的方法是什么？我已经尝试了不同的事情已经有一段时间了，并且没有在任何地方获得
。

I'm building some sort of customer management program and am running aground currently. I have two tables, 'customers' and 'contacts'. In my WinForm I have 2 textboxes and 1 combobox. The textboxes will have the values Name and FirstName for the table contacts respectively and the combobox selects 1 customer from the customers table and I need the ID of that customer to be inserted into contacts aswell. What is the smartest way to do this? I've been trying different things for quite some time now and have not gotten anywhere.
