asp.net零碎知识小结

1.vs2003和vs2005在web.Config中的连接字符串写法：
vs2003将连接字符串写在AppSettings中：
<appSettings >
   <add key="connectionstringName" value="data source=服务器名或IP;initial catalog=数据库名;persist security info=False;user id=用户;password=密码;">
   </add>
</appSettings >
取值方式：System.Configuration.ConfigurationManager.AppSettings["name"]
vs2005将连接字符串写在AppSettings外：
<connectionStrings> 
  <add name="ConnectionStringName" connectionString="Data Source=服务器名;Initial Catalog=数据库名;User ID=用户;Password=密码"
providerName="System.Data.SqlClient" />
</connectionStrings>
取值方式：System.Configuration.ConfigurationManager.ConnectionStrings["name"].ToString()
