如何读取app.config里的connectionstring节.

引用

System.configuration库

读取代码

    Dim connectionString As System.Configuration.ConnectionStringSettings _
                    = System.Configuration.ConfigurationManager.ConnectionStrings("lily")
        MsgBox(connectionString.ConnectionString)

App.config配置文件结构

 

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <connectionStrings>
    <add name="lily" connectionString="server=.;user=sa;pwd=;database=test"/>
  </connectionStrings>
    <system.diagnostics>
