如何获取Web.config的<connecttionString>的连接字符串
请问在vb.net里面怎样获取Web.config的 <connecttionString> 的连接字符串

------解决方案--------------------
ConfigurationSettings.AppSettings[webconfig-AppSettings下的关键字]

------解决方案--------------------
webConfig里这样写如：
<connectionStrings>
　 <add name= "ConnStr " connectionString= "Data Source=.;Initial Catalog=JianCai;User 　　ID=sa;Password= " providerName= "System.Data.SqlClient "/>
</connectionStrings>
前台调用时:
protected SqlConnection con;
con= new SqlConnection(ConfigurationSettings.AppSettings[ "ConnStr "]);

------解决方案--------------------
ConfigurationSettings.AppSettings[]
------解决方案--------------------
ConfigurationSettings.AppSettings[ " "]
------解决方案--------------------
.net 2.0

ConfigurationManager.ConnectionStrings[ "ConnStr "]

楼上正解.
string connStr=ConfigurationManager.ConnectionStrings[ "ConnectionString "].ToString();
SqlConnection conn=new SqlConnection(connStr);
可以反复使用.
