  AjaxFileUpload Error after Upload Files with Double-Byte Character Name

  Feb 19, 2014 02:17 AM|wave0707|LINK

  Hello, I have the same problem like http://forums.asp.net/t/1904733.aspx?AjaxFileUpload+s+problem+Version+7+0429+

  I use AjaxFileUpload in my webform.

  I tried to upload image files.

  Some files with Chinese filename and Japanese filename (double-byte character set).

  I had tried two ways to build my project.

  1. New a web project in my VS2012
  2. Open an web site in my VS2012  from "AjaxControlToolkitSampleSite" folder. 

  AjaxFileUpload1.SaveAs(MapPath("~/App_Data/" + file.FileName));

  Both projects work  fine.  

  There is a problem after I upload files with 'double-byte character' file name.

  It seems ok in upload process.  

  When I open the file with 'double-byte character' name from  "~/App_Data/" folder after I uploaded.  

  Image application shows "file is damaged".

  I had refered from http://www.asp.net/ajaxLibrary/AjaxControlToolkitSampleSite/AjaxFileUpload/AjaxFileUpload.aspx.

  But I didn't find related subjet about the file name encode. 

  Can you please give me some advices?

  Thank you.

  I just google a demo project. The same code has no problem in AjaxControlToolkit (3.5.60501.0) but it can't open correctly in (4.5.7.1213)

  AjaxFileUpload1.SaveAs(MapPath("~/App_Data/" + NewFileName));

  Try replace unwanted character from the FileName with blank character or "-" or space as NewFileName.
