SqlProfileProvider.FindProfilesByUserName 方法

定义

检索用户名与指定名称匹配的配置文件的配置文件信息。

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

usernameToMatchnull

usernameToMatch 为空字符串 ("") 或超过 256 个字符。

- 或 -

pageIndex 小于零。

- 或 -

pageSize 小于一。

- 或 -

pageIndexpageSize 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 pageIndexpageSize 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。
