我想问以下在Win from程序中怎么读取多个add中的连接字符串啊

[午夜小野猫]

<appSettings>
<add key="Data Source" value="."/>
<add key="uid" value="sa"/>
<add key="pwd" value="123"/>
<add key="database" value="MaterialSystem_DB"/>
</appSettings>
在配置文件中是这样的如何才能读取变成一句连接字符串呢？在程序中怎么用这些<add>标签！急在线等谢谢各位大神了

不是有key吗？ 拼接一下就行了 引用System.Configuration

[Forty2]

string dc = System.Configuration.ConfigurationManager.AppSettings["Data Source"]; string id = System.Configuration.ConfigurationManager.AppSettings["uid"]; ...

[EnForGrass]

Configuration config = System.Configuration.ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
//根据Key读取<add>元素的Value
string name = config.AppSettings.Settings["uid"].Value;

[娃都会打酱油了]

string.Format("Data Source={0},uid={1},pwd={2}"
,ConfigurationManager.AppSettings["Data Source"]
,ConfigurationManager.AppSettings["uid]
,ConfigurationManager.AppSettings["pwd])

[你隔壁王大爷]

配置文件中 <connectionStrings> <add name="DefaultConnection" connectionString="Data Source=.;database=MaterialSystem_DB;User ID=sa;Password=123;Integrated Security=True" /> </connectionStrings> 程序运用 protected static string connectionString = ConfigurationManager.ConnectionStrings["DefaultConnection"].ConnectionString;
