web.config中的profile

aspnet_regsql命令创建需要的表结构

  public class UserProfile:ProfileBase
     {
         [SettingsAllowAnonymous(true)]  //默认匿名用户不能访问
         public string MyTest
         {
             get
             {
                 return (string)base["mytest"];
             }
             set
             {
                 base["mytest"] = value;
             }
         }

     }

         <anonymousIdentification enabled="true"/>
         <authentication mode="Forms">

                 <clear/>
                 <add name="mySqlProfileProvider" type="System.Web.Profile.SqlProfileProvider" applicationName="aa.com"  connectionStringName="aspnetdb"    description="mySqlProfileProvider"/>
             </providers>
             <properties>
                 <add name="A" /> <!--默认是string类型，匿名用户能够访问-->
                 <add name="B" type="System.Int32"/>
                 <add name="C" allowAnonymous="false" />
                 <group name="lists">
                     <add name="a" type="int"/>
                 </group>
             </properties>
         </profile>
     </system.web>
     <connectionStrings>
         <add name="aspnetdb" connectionString="Data Source=.;Initial Catalog=aspnetdb;Persist Security Info=True;User ID=sa;Password=123" providerName="System.Data.SqlClient"/>
     </connectionStrings>

在properties中添加的name会放到默认生成的对象ProfileCommon中，ProfileCommon默认继承ProfileBase,但是可以自定义Profile，此时ProfileCommon会继承自定义的Profile【如上文中的UserProfile】。Profile中的信息会持久化到指定的数据库中。
