答

您不需要使用ToArray，因为用户已经是数组，但这不是解决方案.
查看 http://www.c-sharpcorner.com/UploadFile/munnamax/AutocompleteExtender08062007113113854AM/AutocompleteExtender. aspx [ ^ ]并进行更多调试.

You don''t need to use ToArray as user is already an array, but that''s not the solution.
Look at http://www.c-sharpcorner.com/UploadFile/munnamax/AutocompleteExtender08062007113854AM/AutocompleteExtender.aspx[^] and do some more debugging.
