【WinForm】 自学笔记二：连接数据库以及查询结果显示
本次使用 SqlConnection 来连接数据库，使用 DataGridView 来显示查询的结果。最终效果如下：一、连接数据库
1.获取连接数据库所需的字符串，包括服务器名称，数据库名称，用户名以及密码，可在配置文件中配置，或直接在代码里写死
在配置文件 App.config 中配置的代码：
<configuration>
<appSettings>
<add key="connectionstring" value="server=192.168.3.201;database=Nine_Xhs;uid=sa;pwd=Nine!2021;"/>
</appSettings>

1.在窗口中添加 DataGridView 对象，用于显示数据
右键点击 DataGridView 对象，可以编辑要显示的列，以及表头的名称。
列属性：
DataPropertyName : 数据源中对应字段的名称，根据对应的字段来显示值
HeaderText : 表头显示的文字
DataGridView属性
AllowUserToAddRows ：DataGridView默认底部有一行空数据，将改属性修改为False,可以隐藏空白行
AutoSizeColumnsMode：控制列的宽度，将该属性ScrollBars修改为 Fill , 能让列的宽度自适应，充满整个画面
ScrollBars ： 控制滚动条的状态，可隐藏滚动条，或只显示水平或垂直的滚动条
2.生成数据查询SQL，并将查询结果绑定到 DataGridView 上，在画面进行显示
