Examples
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.
using System;
using System.Web.Profile;
namespace Samples.AspNet.Profile
{
public class EmployeeProfile : ProfileBase
{
[SettingsAllowAnonymous(false)]
[ProfileProvider("EmployeeInfoProvider")]
public string Department
{
get { return base["EmployeeDepartment"].ToString(); }
set { base["EmployeeDepartment"] = value; }
}
[SettingsAllowAnonymous(false)]
[ProfileProvider("EmployeeInfoProvider")]
public EmployeeInfo Details
{
get { return (EmployeeInfo)base["EmployeeInfo"]; }
set { base["EmployeeInfo"] = value; }
}
}
public class EmployeeInfo
{
public string Name;
public string Address;
public string Phone;
public string EmergencyContactName;
public string EmergencyContactAddress;
public string EmergencyContactPhone;
}
}
Imports System.Web.Profile
Namespace Samples.AspNet.Profile
Public Class EmployeeProfile
Inherits ProfileBase
<SettingsAllowAnonymous(False)> _
<ProfileProvider("EmployeeInfoProvider")> _
Public Property Department As String
Get
Return MyBase.Item("EmployeeDepartment").ToString()
End Get
Set
MyBase.Item("EmployeeDepartment") = value
End Set
End Property
<SettingsAllowAnonymous(False)> _
<ProfileProvider("EmployeeInfoProvider")> _
Public Property Details As EmployeeInfo
Get
Return CType(MyBase.Item("EmployeeInfo"), EmployeeInfo)
End Get
Set
MyBase.Item("EmployeeInfo") = value
End Set
End Property
End Class
Public Class EmployeeInfo
Public Name As String
Public Address As String
Public Phone As String
Public EmergencyContactName As String
Public EmergencyContactAddress As String
Public EmergencyContactPhone As String
End Class
End Namespace
Remarks
The ProfileProviderAttribute class is used to identify the profile provider for a property of a custom profile implementation. A custom profile implementation is a class 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 type for the user profile using the inherits attribute of the profile configuration element in the Web.config file for an application, as shown in the following example.
<configuration>
<connectionStrings>
<add name="SqlServices" connectionString=
"Data Source=localhost;Integrated Security=SSPI;Initial Catalog=aspnetdb;" />
</connectionStrings>
<system.web>
<authentication mode="Forms" >
<forms loginUrl="login.aspx"
name=".ASPXFORMSAUTH" />
</authentication>
<authorization>
<deny users="?" />
</authorization>
<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>
</configuration>
Constructors

Creates a new instance of the ProfileProviderAttribute class with the specified profile provider name. |
Properties
| ProviderName |
Gets the name of the profile provider for the user-profile property. |
| TypeId |
When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute) |
Methods
| Equals(Object) |
Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute) |
| GetHashCode() |
Returns the hash code for this instance. (Inherited from Attribute) |
| GetType() |
Gets the Type of the current instance. (Inherited from Object) |
| IsDefaultAttribute() |
When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute) |
| Match(Object) |
When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute) |
| MemberwiseClone() |
Creates a shallow copy of the current Object. (Inherited from Object) |
| ToString() |
Returns a string that represents the current object. (Inherited from Object) |
Explicit Interface Implementations
| _Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr) |
Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute) |
| _Attribute.GetTypeInfo(UInt32, UInt32, IntPtr) |
Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute) |
| _Attribute.GetTypeInfoCount(UInt32) |
Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute) |
| _Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr) |
Provides access to properties and methods exposed by an object. (Inherited from Attribute) |
