推荐答案

如果您无法从数据库中读取数据，数据库会有什么好处?这是一个SELECT查询.

那里有数以百万计的示例，还有许多其他不同的实现方法.

ASPX只是ASP.NET应用程序中的页面. .cs文件是C#代码文件.在ASP.NET应用程序和普通的Windows Forms应用程序中执行此操作之间没有区别，二者均使用C#编写.

让我让您开始使用简单的Google查询-> [ ^ ]

What good would a database be if you couldn''t read data from it?? It''s a SELECT query.

There''s millions upon millions of examples on this out there and more than a few different ways to do it.

ASPX is just a page from an ASP.NET application. A .cs file is a C# code file. There is no difference between doing this operation in an ASP.NET app and a normal Windows Forms app, either of which is written in C#.

Let me get you started wit ha simple Google query -> "C# get data from database"[^]

ummm ... sqldatareader和sqldataadapter是两种方法，一种是连接的，而另一种是断开连接的体系结构.您可以在网上找到有关ado.net，linq和其他数据库程序交互方式的示例

ummm...sqldatareader and sqldataadapter are two approaches, one connected and other is disconnected architecture. you can find examples for both around the web for ado.net, linq and other means of db-program interaction
