Gets an array of user names in a role where the user name contains the specified user name to match.
A string array containing the names of all the users where the user name matches usernameToMatch and the user is a member of the specified role.
The RoleProvider.FindUsersInRole(string, string) method is called by the System.Web.Security.Roles class and returns a list of users in a role where the user name contains a match of the supplied usernameToMatch for the configured applicationName. Wildcard support is included based on the data source. Users are returned in alphabetical order by user name.
We recommend that you throw a System.Configuration.Provider.ProviderException if roleName does not exist in the data source.
