Good Day 
 
i am using a AsyncUpload(telerik), i am in a point where i am supposed to save the File to a certain Folder. 


First i check if the directory exist 
 
 
Dim baseDire As String = Server.MapPath("~/MyFILES/")
If IO.Directory.Exists(baseDire & Request("Req_ID").ToString()) = False Then
               IO.Directory.CreateDirectory(baseDire & Request("Req_ID").ToString())
           End If

 
Because i am doing multiple Upload  , i will have to loop through the items of the Upload control and save to a folder. 


For Each file As UploadedFile In UploadPropDoc.UploadedFiles
              Dim bytes(file.ContentLength - 1) As Byte
              file.InputStream.Read(bytes, 0, file.ContentLength)
               'Save the File to the disk
              file.SaveAs(baseDire + file.GetName())
          Next



Now when ever i debug this , when it comes to this line 


file.SaveAs(baseDire + file.GetName())
 


i get an Error 
 
 The process cannot access the file because it is being used by another process 
 


I have removed the Readonly in the Folder that it supposed to write to and gave everyone permission , but still the error persist.


Thanks

Vuyiswa,

Since you did not post your entire code, it's a bit hard to know what is locking the file. But, It looks like you may not be properly creating and releasing the stream that you're feeding to file.InputStream. This process is covered very comprehensively in the IOException when saving forum thread.

If you cannot find the solution in this thread, I'd suggest posting your entire code for review.

Hope this helps!

hi jumpstart

Thanks , the issue was that i was not closing the Stream. One other thing is that i thought i had to create the file and save it to a certain folder myself , i later looking at the documentation i realised that every postback it post the uploaded files to the "TargetFolder" which is very cool. 

Thanks
