如何获取数据集数据以更新数据库 [英] How do I get a Dataset data to update the database

问题描述

我正在使用c＃express和sql express来创建我的程序。我已经建立了一个关系数据库，并使用不同风格的几种不同形式进行数据输入。我正在使用命名数据集，并且在将数据从数据集更新到
数据库时遇到问题。我尝试了几种不同的方法，包括使用endsit循环来更新数据库。我不断收到错误主键错误。我在编程方面已经很生疏20年了（我在
大学学习了C编程课程），但我没有做任何困难的事情，也不认为应该这么复杂。由于我有10个表单，如果可以的话，我不想为每个表单编写更新程序。我从microsoft文档中读到的信息似乎都没有工作

I am using c# express and sql express to create my program. I have set up a relational database and am using several different forms in different styles for data entry. I am using named datasets and having problems updating data from the datasets to the database. I have tried several different methods, including looping with endedit to update the database. I keep getting errors a duplicate primary key error. I am really rusty at programming having not done it for 20 years(I took a C programming course in University) but I am not doing anything that difficult and don't think it should be so complicated. As I have 10 forms, I don't want to write an update procedure for each but one if I can. None of the info I read from the microsoft documentation seems to work
