Serialization Exception

Reply Quote

I have the Session management set to Sql Server in IIS for my application that uses the ajax uploader control. It is erring out doing the uploader and I believe it is happening on the line of code where I set a Session variable to the args of type UploaderEventArgs. Here is the code:

Protected Sub Attachments1_FileUploaded(ByVal sender As System.Object, ByVal args As CuteWebUI.UploaderEventArgs) Handles Attachments1.FileUploaded

Session("UploadFile") = args

propFilename = args.FileName

validRequest = True

btnContinue.Enabled = True

End Sub

And here is the exception from event viewer:

Exception information:

Exception type: SerializationException

Exception message: Type 'CuteWebUI.UploaderEventArgs' in Assembly 'CuteWebUI.AjaxUploader, Version=3.0.0.0, Culture=neutral, PublicKeyToken=bc00d4b0e43ec38d' is not marked as serializable.

Hi,

The UploaderEventArgs is a temporary object, you shall not save it to Session.

You can save the args.FileGuid instead.

and use

new MvcUploader(HttpContext).GetUploadedFile

to get the file object
