在链接数据库的时候出现问题 ，但是用sa sa123能登陆sqlserver 2005

 SqlConnection sqlon = new SqlConnection();
        sqlon .ConnectionString ="Data Source=LENOVO-201307070958.\\sqlexpress;Database=Table1;Uid=sa;Pwd=sa123";
        sqlon.Open();

求解！求解！！！！！

SqlConnection sqlon = new SqlConnection();
        sqlon .ConnectionString ="Data Source=LENOVO-201307070958.\\sqlexpress;Database=Table1;Uid=sa;Pwd=sa123";
        sqlon.Open();

可以在webconfig里加这个试试
<appSettings>
        <add key="ConnectionString" value="server=LENOVO-201307070958\sqlexpress;Database=Table1;Uid=sa;Pwd=sa123" />
 </appSettings>
