In this article I am going to explain more about Profile object. In my previous article about Profiles, I explained that we can not use Profile object directly like as session or cookies. To use Profile object we have to register database. See my previous article of Profile to see how to register the database.
How site, remember my information which I changed? This is done by Profile.
The Profile provider in ASP.NET stores and retrieves information about our site' users. The default profile provider keeps data in SQL Server tables.
For this we have to do some changes in web.config file.
web.config
<?xml version="1.0"?>
<configuration>
<appSettings/>
<connectionStrings>
<add name="ConnectionString" connectionString="Server=localhost;Database=MergeTable;Uid=sa; pwd="/>
</connectionStrings>
<system.web>
<anonymousIdentification enabled="true"/>
<trust level="High"/>
<profile defaultProvider="MyProfileProvider" >
<providers>
<add name="MyProfileProvider" type="System.Web.Profile.SqlProfileProvider" connectionStringName="ConnectionString" />
</providers>
<properties>
<add name="Name" allowAnonymous="true" />
<add name="City" allowAnonymous="true" />
<add name="Country" allowAnonymous="true" />
<add name="ID" allowAnonymous="true" type="System.Int32" />
</properties>
</profile>
<compilation debug="true"/>
<authentication mode="Windows"/>
</system.web>
</configuration>
