Incorrect file length - how to solve this ?

[Vasssek]

Hello,

I wonder if somebody knows how to get real file size (length) of the uploaded file. In my application I use this method:

protected void fileUploaded(object sender, FileUploadedEventArgs e)
        {
            try
            {
                if (RadAsyncUpload1.UploadedFiles.Count > 0)
                {
                    if (targetPersonalTmpFolder.Exists.Equals(false)) targetPersonalTmpFolder.Create();

                    foreach (UploadedFile uploadedFile in RadAsyncUpload1.UploadedFiles)
                    {
                        //UploadedFileInfo uploadedFileInfo = new UploadedFileInfo(uploadedFile);

                        string fullPath = Path.Combine(targetPersonalTmpFolder.ToString(), uploadedFile.GetName());
                        uploadedFile.SaveAs(fullPath, true);
                       
                        TmpFiles_List.Add(new UplodedFileData()
                        {
                            FileName = uploadedFile.GetName(),
                            FullFileName = targetPersonalTmpFolder.ToString() + @"\" + uploadedFile.GetName(),
                            //FileContentLength = Math.Round(uploadedFile.InputStream.Length / 1024d, 0).ToString() + " KB"
                            FileContentLength = Math.Round(uploadedFile.ContentLength / 1024d, 0).ToString() + " KB"
                        });
                       
                    }

                    BindFiles();
                    BindTmpFiles();
                }
            }
            catch (Exception ex)
            {
                //Pravdepodobne bol stlaceny klaves F5 refresh stranky...
                ReinitializeForm();
            }
        }

The problem is that property uploadedFile.ContentLength doesn't return real length of the file. I've found that this uploadedFile.InputStream.Length returns correct file size, but when I tried to use it, then this error appeared: The process cannot access the file because it is being used by another process...

Something similar is described here: http://www.telerik.com/community/forums/aspnet-ajax/async-upload/temporary-files-locked-after-upload.aspx

Please help me to solve this issue...

Hello Vasssek,

Indeed such issue exist. We are ought to fix it for the upcoming Q1 release, meanwhile you could use the following workaround:

void RadAsyncUpload1_FileUploaded(object sender, FileUploadedEventArgs e)
    {
        using (var stream = e.File.InputStream)
        {
            var length = stream.Length;
        }
    }

Hello Genady,

your workaround didn't work. For further info please check attachment. Maybe it's because I've decided to use the last official release version 2010.3.1317.35.

Instead of that, I've created a new fileinfo object and get real file length:

string fullPath = Path.Combine(targetPersonalTmpFolder.ToString(), uploadedFile.GetName());
uploadedFile.SaveAs(fullPath, true);

FileInfo fileInfo = new FileInfo(fullPath);

TmpFiles_List.Add(new UplodedFileData()
{
     FileName = uploadedFile.GetName(),
     FullFileName = targetPersonalTmpFolder.ToString() + @"\" + uploadedFile.GetName(),
     //FileContentLength = Math.Round(uploadedFile.InputStream.Length / 1024d, 0).ToString() + " KB"
     //FileContentLength = Math.Round(uploadedFile.ContentLength / 1024d, 0).ToString() + " KB"
     FileContentLength = Math.Round(fileInfo.Length / 1024d, 0).ToString() + " KB"
});

Anyway, thank you for your advice...

Best regards
