在Web.Config文件中有下面的连接字符串，我想在.aspx.cs文件中去使用它（goodsmisdbConnectionString），但是不知怎样才能引用到。请求您的帮助，先谢谢了啊！
<configuration>
<connectionStrings>
<add name="goodsmisdbConnectionString" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\goodsmisdb_Data.MDF;Integrated Security=True;User Instance=True"
providerName="System.Data.SqlClient" />
</connectionStrings>
.....
</configuration>

<configuration>
<appSettings>
<add key="goodsmisdbConnectionString" value="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\goodsmisdb_Data.MDF;Integrated Security=True;User Instance=True"/>
</appSettings>
....
....
....

调用:
string connStr = System.Configuration.ConfigurationManager.AppSettings["goodsmisdbConnectionString"].ToString();

多谢BYGG了，用<add key="goodsmisdbConnectionString2" value="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\goodsmisdb_Data.MDF;Integrated Security=True;User Instance=True"/>果然解决了问题
原来用这个也行static string constring = System.Configuration.ConfigurationManager.ConnectionStrings["goodsmisdbConnectionString"].ToString();

static string constring = System.Configuration.ConfigurationManager.ConnectionStrings["goodsmisdbConnectionString"].ToString();

为何用加上 static ？？？

不加也行，
