Assembly: System.Web (in system.web.dll)
'Declaration Public Shared Function GetUser ( _ username As String, _ userIsOnline As Boolean _ ) As MembershipUser 'Usage Dim username As String Dim userIsOnline As Boolean Dim returnValue As MembershipUser returnValue = Membership.GetUser(username, userIsOnline)
public static MembershipUser GetUser ( String username, boolean userIsOnline )
public static function GetUser ( username : String, userIsOnline : boolean ) : MembershipUser
Not applicable.
Parameters
- username
The name of the user to retrieve.
- userIsOnline
If true, updates the last-activity date/time stamp for the specified user.
Return Value
A MembershipUser object representing the specified user.The GetUser method retrieves the user information from the data source and creates a MembershipUser object populated with the returned data.
If you use one of the GetUser overloads that does not take a username parameter, GetUser returns the information for the current logged-on membership user. The current logged-on membership user is identified by the Name of the user in the current HttpContext.
You can also specify whether you want GetUser to update the last-activity date/time stamp for the user being retrieved with the userIsOnline parameter. Of the GetUser overloads that do not take a userIsOnline parameter, Membership.GetUser implicitly updates the last-activity date/time stamp for the user. Membership.GetUser and GetUser do not.
The following code example retrieves the password for a specified user name and sends it to the e-mail address for the specified user. The call to GetUser specifies that the last-activity date/time stamp for the user not be updated.
