注解

ASP.NET 配置文件用于在数据源（如数据库）中存储和检索用户设置。使用 Profile 当前 HttpContext的属性访问用户配置文件。配置文件信息和属性值使用配置文件提供程序进行管理。

类 ProfileManager 用于管理配置文件设置、搜索用户配置文件以及删除不再使用的用户配置文件。类 ProfileManager 提供静态方法和属性，可通过在应用程序代码中引用 ProfileManager 类来访问这些方法和属性。有关示例，请参阅本主题中的示例部分，以及有关类成员 ProfileManager 的主题中的其他示例。

默认情况下，对所有 ASP.NET 应用程序禁用用户配置文件。若要启用用户配置文件，请将enabled配置文件配置元素的属性设置为 true，如以下示例所示。

<configuration>
  <system.web>
    <profile enabled="true" />
  </system.web>
</configuration>

有关用户配置文件的详细信息，请参阅 ASP.NET 配置文件属性概述。

配置文件提供程序用于存储和检索用户配置文件中的属性。 .NET Framework包含一个SqlProfileProvider类，该类将用户配置文件属性存储在SQL Server数据库中。名为 SqlProfileProvider 的 AspNetSqlProvider 实例在计算机配置中指定为默认配置文件提供程序。实例AspNetSqlProvider连接到本地 Web 服务器上的 SQL Server 数据库。可以使用提供程序配置元素和defaultProvider配置文件配置元素的属性将SqlProfileProvider连接到另一SQL Server指定为默认配置文件提供程序，如以下示例所示。

<configuration>
  <connectionStrings>
    <add name="SqlServices" connectionString=
      "Data Source=MySqlServer;Integrated Security=SSPI;Initial Catalog=aspnetdb;" />
  </connectionStrings>
  <system.web>
    <profile defaultProvider="SqlProvider">
      <providers>
        <clear />
        <add name="SqlProvider"
          type="System.Web.Profile.SqlProfileProvider"
          connectionStringName="SqlServices"
          applicationName="MyApplication" />
      </providers>
    </profile>
  </system.web>
</configuration>

属性

ApplicationName	获取或设置要存储和检索其配置文件信息的应用程序的名称。
AutomaticSaveEnabled	获取一个值，该值指示是否将在 ASP.NET 页执行结束时自动保存用户配置文件。
Enabled	获取一个值，该值指示是否为应用程序启用用户配置文件。
Provider	获取对应用程序的默认配置文件提供程序的引用。
Providers	获取 ASP.NET 应用程序的配置文件提供程序的集合。

方法

AddDynamicProfileProperty(ProfilePropertySettings)	以编程方式添加配置文件属性。
DeleteInactiveProfiles(ProfileAuthenticationOption, DateTime)	删除上次活动日期和时间出现在指定日期和时间之前的用户配置文件数据。
DeleteProfile(String)	从数据源中删除指定用户名的配置文件。
DeleteProfiles(ProfileInfoCollection)	从数据源中删除提供的一系列配置文件的配置文件属性和信息。
DeleteProfiles(String[])	删除提供的一系列用户名的配置文件属性和信息。
FindInactiveProfilesByUserName(ProfileAuthenticationOption, String, DateTime)	检索所有配置文件的配置文件信息，在这些配置文件中，上次活动日期与指定的日期和时间相同或在其之前，而且配置文件的用户名与指定的名称匹配。
FindInactiveProfilesByUserName(ProfileAuthenticationOption, String, DateTime, Int32, Int32, Int32)	以分页数据的形式检索一些配置文件的配置文件信息，在这些配置文件中，上次活动日期与指定的日期和时间相同或在其之前，而且配置文件的用户名与指定的名称匹配。
FindProfilesByUserName(ProfileAuthenticationOption, String)	检索用户名与指定名称匹配的配置文件的所有配置文件信息。
FindProfilesByUserName(ProfileAuthenticationOption, String, Int32, Int32, Int32)	以分页数据的形式检索用户名与指定名称匹配的配置文件的配置文件信息。
GetAllInactiveProfiles(ProfileAuthenticationOption, DateTime)	对于上次活动日期与指定的日期和时间相同或在其之前的配置文件，检索它们的所有用户配置文件数据。
GetAllInactiveProfiles(ProfileAuthenticationOption, DateTime, Int32, Int32, Int32)	对于上次活动日期与指定的日期和时间相同或在其之前的用户配置文件，检索它们的 ProfileInfo 对象的页面。
GetAllProfiles(ProfileAuthenticationOption)	在数据源中检索配置文件的用户配置文件数据。
GetAllProfiles(ProfileAuthenticationOption, Int32, Int32, Int32)	检索用户配置文件数据的页面。
GetNumberOfInactiveProfiles(ProfileAuthenticationOption, DateTime)	获取上次活动日期与指定日期相同或在其之前的配置文件的数目。
GetNumberOfProfiles(ProfileAuthenticationOption)	获取数据源中的配置文件数量。
