ProfileProviderAttribute Class

Definition

Identifies the profile provider for a user-profile property.

public ref class ProfileProviderAttribute sealed : Attribute
[System.AttributeUsage(System.AttributeTargets.Property)]
public sealed class ProfileProviderAttribute : Attribute
type ProfileProviderAttribute = class
    inherit Attribute

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>
