FindUsersByName returns a list of membership users where the user name matches the supplied usernameToMatch for the configured applicationName.
The SqlMembershipProvider performs its search using a LIKE clause against the usernameToMatch parameter. Any wildcards that are supported by SQL Server in LIKE clauses can be used in the usernameToMatch parameter value.
The results returned by FindUsersByName are constrained by the pageIndex and pageSize parameters. The pageSize parameter identifies the maximum number of MembershipUser objects to return in the MembershipUserCollection. The pageIndex parameter identifies which page of results to return, where 0 identifies the first page. The totalRecords parameter is an out parameter that is set to the total number of membership users that matched the usernameToMatch value. For example, if 13 users were found where usernameToMatch matched part of or the entire user name, and the pageIndex value was 1 with a pageSize of 5, the MembershipUserCollection returned would contain the sixth through the tenth users returned. totalRecords would be set to 13.
The following code example uses the FindUsersByName method to retrieve membership user information from the membership database based on user input and displays the results in pages of data.
