public:
override System::Web::Profile::ProfileInfoCollection ^ FindProfilesByUserName(System::Web::Profile::ProfileAuthenticationOption authenticationOption, System::String ^ usernameToMatch, int pageIndex, int pageSize, [Runtime::InteropServices::Out] int % totalRecords);
public override System.Web.Profile.ProfileInfoCollection FindProfilesByUserName (System.Web.Profile.ProfileAuthenticationOption authenticationOption, string usernameToMatch, int pageIndex, int pageSize, out int totalRecords);
override this.FindProfilesByUserName : System.Web.Profile.ProfileAuthenticationOption * string * int * int * int -> System.Web.Profile.ProfileInfoCollection
Public Overrides Function FindProfilesByUserName (authenticationOption As ProfileAuthenticationOption, usernameToMatch As String, pageIndex As Integer, pageSize As Integer, ByRef totalRecords As Integer) As ProfileInfoCollection
参数
- authenticationOption
- ProfileAuthenticationOption
ProfileAuthenticationOption 值之一,指定是返回匿名配置文件、经过身份验证的配置文件还是同时返回这两种类型的配置文件。
- usernameToMatch
- String
要搜索的用户名。
- pageIndex
- Int32
要返回的结果页的索引。
pageIndex
从零开始。
- pageSize
- Int32
要返回的结果页的大小。
- totalRecords
- Int32
此方法返回时,会包含一个表示配置文件总数的整数。 此参数未经初始化即被传递。
返回
包含配置文件中的用户配置文件信息的 ProfileInfoCollection,其中的用户名与提供的 usernameToMatch
参数相匹配。
例外
usernameToMatch
为 null
。
usernameToMatch
为空字符串 ("") 或超过 256 个字符。
- 或 -
pageIndex

- 或 -
pageIndex
乘 pageSize
以 大于 Int32.MaxValue。
示例
下面的代码示例允许用户提供 usernameToMatch
值和 , ProfileAuthenticationOption 并检索任何匹配配置文件的配置文件信息。 该示例还允许用户指定是否以独占方式返回非活动配置文件。 如果用户仅指定非活动配置文件,则 FindInactiveProfilesByUserName 调用 方法;否则调用 FindProfilesByUserName 方法。

注解
方法FindInactiveProfilesByUserName返回配置文件信息的列表,配置文件的用户名与配置的 ApplicationName提供usernameToMatch
的参数值匹配。
authenticationOption
使用 参数指定是要只搜索匿名配置文件、仅经过身份验证的配置文件还是搜索所有配置文件。
使用 SqlProfileProviderLIKE
关键字搜索参数值的匹配usernameToMatch
项,并支持通配符,例如百分比 (%) 符号。 例如,如果 usernameToMatch
参数设置为“user1”,则返回用户名为“user1”的配置文件信息(如果存在)。
usernameToMatch
如果参数设置为“user%”,则返回用户名为“user1”、“user2”、“user_admin”等的配置文件的配置文件信息。 用户按其配置文件添加到数据存储区的顺序返回。
返回 FindProfilesByUserName 的结果受 pageIndex
和 pageSize
参数的约束。 参数pageSize
标识在 中ProfileInfoCollection返回的最大对象数ProfileInfo。 参数 pageIndex
标识要返回的结果页;0 标识第一页。 参数totalRecords
是一个out
参数,它根据 和 userInactiveSinceDate
参数设置为配置文件authenticationOption
中的 属性指定的applicationName
应用程序的非活动用户配置文件总数。 例如,如果配置的 applicationName
有 13 个用户,并且 pageIndex
值为 1,值为 pageSize
5, ProfileInfoCollection 则返回的 将包含第六个到第十个配置文件。 参数 totalRecords
将设置为 13。
