Examples
The following code example shows a Web.config file that specifies a user profile that contains a ZipCode
property of type string
and a RecentSearchList
property of type StringCollection. The generated Profile property of the current HttpContext will have strongly typed accessors for each of the specified properties.
<configuration>
<system.web>
<anonymousIdentification enabled="true" />
<profile enabled="true" defaultProvider="SqlProvider" >
<properties>
<add name="ZipCode" allowAnonymous="true" />
<add name="RecentSearchList"
type="System.Collections.Specialized.StringCollection"
serializeAs="Xml"
allowAnonymous="true" />
</properties>
</profile>
</system.web>
</configuration>
The following example shows an ASP.NET page that reads and sets the ZipCode
property specified for the user profile. Before attempting to run this code, set the provider to the default AspNetSqlProvider
in the ASP.NET configuration settings for the Web site.

The following code example defines a class that inherits from the ProfileBase class to create a custom profile. The type of the custom profile is specified in the inherits
attribute of the profile configuration element in the Web.config file for an application.
Important
This example contains a text box that accepts user input, which is a potential security threat. By default, ASP.NET Web pages validate that user input does not include script or HTML elements. For more information, see Script Exploits Overview.

Remarks
ASP.NET uses the ProfileBase class to create the class used for the user profile. When an application that has the user profile enabled is started, ASP.NET creates a new class of type ProfileCommon
, which inherits from the ProfileBase class. Strongly typed accessors are added to the ProfileCommon
class for each property defined in the profile configuration section. The strongly typed accessors of the ProfileCommon
class call the GetPropertyValue and SetPropertyValue methods of the ProfileBase base class to retrieve and set profile property values, respectively. An instance of the ProfileCommon
class is set as the value of the Profile property for the ASP.NET application.
To create an instance of a user profile in an ASP.NET application, it is recommended that you use the Create method.
Notes to Inheritors
You can create a custom profile implementation that inherits from the ProfileBase abstract class and defines properties for the user profile that are not specified in the profile configuration element. You can specify a custom user-profile type in the web.config file with the inherits
attribute of the profile configuration element, as shown in the following example. The code for the EmployeeProfile
class is included in the Example section of this topic.
<configuration>
<system.web>
<profile inherits="Samples.AspNet.Profile.EmployeeProfile"
defaultProvider="SqlProvider">
<providers>
<clear />
<add
name="SqlProvider"
type="System.Web.Profile.SqlProfileProvider"
connectionStringName="SqlServices"
description="SQL Profile Provider for Sample"/>
<add
name="EmployeeInfoProvider"
type="System.Web.Profile.SqlProfileProvider"
connectionStringName="SqlServices"
description="SQL Profile Provider for Employee Info"/>
</providers>
<properties>
<add name="GarmentSize" />
</properties>
</profile>
</system.web>
