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:

sqlserver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 >
