连接字符串

VS中自建数据库的连接字符串：”DataSource=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\数据库名.mdf;Integrated Security=True;User Instance=True ”

WebConfig中两种不同的连接字符串:

     <connectionStrings>         
        <add name="DataBase" connectionString="Server=.\sqlexpress;Database=数据库名;uid=sa;pwd=sa;" providerName="System.Data.SqlClient"/>         
        <add name="ConnectionString" connectionString="DataSource=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\数据库名.mdf;Integrated Security=True;User Instance=True"             
         providerName="System.Data.SqlClient"/>         
</connectionStrings>             引用：string myConnectionString = ConfigurationManager.ConnectionString["ConnectionString"].ConnectionString;        给大家提供一个所有类型的连接字符串的写法的查询网址：http://www.connectionstrings.com/
