在数据层，我试图从app.config获取连接字符串 .
App.config中
<connectionStrings>
<add name="DBConnection" connectionString="Data Source=****;Initial Catalog=****;Persist Security Info=True;User ID=*****; Password=***" />
</connectionStrings>
获取 Value ：
Shared _ConnectionString As String = System.Configuration.ConfigurationManager.ConnectionStrings("DBConnection").ConnectionString
这不起作用 .
我试过了
Shared _ConnectionString As String = System.Configuration.ConfigurationManager.ConnectionStrings(0).ConnectionString
它是部分提取 - “数据源= ****;初始目录= ****;持久安全信息=真”
请解释一下 .

尝试使用
ConnectionStrings["DBConnection"].ConnectionString而不是ConnectionStrings("DBConnection").ConnectionString.
