VS2003中Webconfig里的 数据库链接语句 转到 2005无法使用。？
Public   Sub   New()

                System.Configuration.ConfigurationManager.AppSettings( "connectingstring ").ToString.Trim()
                myConn   =   New   SqlConnection(connectingstring)

        End   Sub
错误提示：   无法找到     connectingstring
怎么办？
2005：            
    <add   name= "connectingstring "   connectionString= "Data   Source=FOX-START;Initial   Catalog=waigua;User   ID=sa "
                        providerName= "System.Data.SqlClient "   />

2003：
<add   key= "ConnectionString "   value= "server=localhost;database=Contract:UID=user;password=user "/>

connectionString= "Data Source=LEXOPC;Initial Catalog=Northwind;Persist Security Info=True;User ID=cofei;Password=cofei " providerName= "System.Data.SqlClient "
