立刻结贴：连接字符串问题
我如果连接SqlExpress中的内置的Northwind数据库，可以这样：
SqlConnection   conn;
conn   =   new   SqlConnection( "Data   Source   =   .\\SQLExpress;Initial   Catalog   =   Northwind;   Integrated   Security   =   SSPI ");

但我现在要连自己的数据库，比如
E:\WEB\PWS网站\APP_DATA\ASPNETDB.MDF；
这个的话，我的连接字符串应该怎么写呢？？？把它加入到我的sqlserver服务器里，也是这么个地址加名称，我直接写到连接字符串里，就出错啊~~~~

求救~~得到答案就结贴！

SqlConnection cn = new SqlConnection(System.Configuration.ConfigurationManager.AppSettings[ "ConnectingString "]);


<appSettings>
<add key= "ConnectingString " value= "Data Source=localhost;user id=sa;password=;initial catalog=lydoor "/>

SqlConnection conn;
conn = new SqlConnection( "server=127.0.0.1;uid=数据库用户名;pwd=数据库密码;DataBase=数据库 ");

<appSettings>
<!-- 数据库连接字符串 -->
<add key= "ConnString " value= "Data Source=(local);database=数据库名;UID=sa;Password=sa;Persist Security Info=True; " />
</appSettings>
------解决方案--------------------
SqlConnection conn;
conn = new SqlConnection( "server=.;user=sa;pwd=;DataBase=数据库名称 ");

如果是SQL2005直接如下应该是可以的吧:
SqlConnection conn;
conn = new SqlConnection( "Data Source = .\\SQLExpress;Initial Catalog = ASPNETDB; Integrated Security = SSPI ");
------解决方案--------------------
<connectionStrings>
<add name= "ConnectionString " connectionString= "Data Source =(local);uid=用户名;pwd=数据库密码;database=数据库名称 ">
</connectionStrings>

sqlconnection conn=new sqlconnection(configurationmanager.connectionstrings[ "ConnectionStirng "].connectionstring);
