求教如何取Appconfig的值

Question

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <connectionStrings>
    <add name="ConnectionString" connectionString="DSN=MS Access Database;DBQ=E:\MyTest\ReflectionDataBase\ReflectionDataBase\bin\Debug\changqing.mdb;DefaultDir=E:\MyTest\ReflectionDataBase\ReflectionDataBase\bin\Debug;DriverId=25;FIL=MS Access;MaxBufferSize=2048;PageTimeout=5;UID=admin"/>
  </connectionStrings>
</configuration>App.Config里面有个ConnectionString，想要取得这个连接字符串怎么弄？
如果是AppSetting里的节点直接用ConfigurationSettings.AppSettings["connectionString"].ToString();就能取，但是换成connectionStrings就没辙了

Answer 1

 System.Configuration.ConfigurationManager.ConnectionStrings["XXXX"];

Answer 2

额～再问下，是不是form不支持？

Answer 3

ConnectionStrings["xxx"].connectionString

Answer 4

public static string ConnectionString= System.Web.Configuration.WebConfigurationManager.AppSettings["ConnectionString"];

Answer 5

<appSettings>
<add key="DBConnectionString" value="这里写链接数据库字符串"/>
</appSettings>

Answer 6

Properties.Settings.Default.connectionString
你只要看看Settings.settings文件关联的源代码就知道了

Answer 7

Properties.Settings.Default.ConnectionString 
ConnectionString就是<add name="ConnectionString" .....>里的字符串
