The process cannot access the file '…' because it is being used by another process


I have a code to delete file in my folder, but in my line code, I want to delete two file together with different folder. But I always get an error "the process cannot access.... another process". May be you can correct my code and give me a solution. Thanks

1) I have a code to generate watermark when save file(.pdf):

public bool InsertWaterMark(string path) { bool valid = true; string FileDestination = AppDomain.CurrentDomain.BaseDirectory + "Content/" + path; string FileOriginal = AppDomain.CurrentDomain.BaseDirectory + "Content/" + path.Replace("FileTemporary", "FileOriginal"); System.IO.File.Copy(FileDestination, FileOriginal); string watermarkText = "Controlled Copy"; #region process PdfReader reader1 = new PdfReader(FileOriginal);//startFile using (FileStream fs = new FileStream(FileDestination, FileMode.Create, FileAccess.Write, FileShare.None))//watermarkedFile { using (PdfStamper stamper = new PdfStamper(reader1, fs)) { int pageCount1 = reader1.NumberOfPages; PdfLayer layer = new PdfLayer("WatermarkLayer", stamper.Writer); for (int i = 1; i <= pageCount1; i++) { iTextSharp.text.Rectangle rect = reader1.GetPageSize(i); PdfContentByte cb = stamper.GetUnderContent(i); cb.BeginLayer(layer); cb.SetFontAndSize(BaseFont.CreateFont(BaseFont.HELVETICA, BaseFont.CP1252, BaseFont.NOT_EMBEDDED), 80); PdfGState gState = new PdfGState(); gState.FillOpacity = 0.15f; cb.SetGState(gState); cb.SetColorFill(BaseColor.GRAY); cb.BeginText(); cb.ShowTextAligned(PdfContentByte.ALIGN_CENTER, watermarkText, rect.Width / 2, rect.Height / 2, 45f); cb.EndText(); PdfContentByte canvas = stamper.GetUnderContent(i); BaseFont bf = BaseFont.CreateFont(BaseFont.HELVETICA_OBLIQUE, BaseFont.CP1252, BaseFont.NOT_EMBEDDED); canvas.SetColorFill(BaseColor.RED); PdfGState gStateFooter = new PdfGState(); gStateFooter.FillOpacity = 1f; canvas.SetGState(gStateFooter); canvas.BeginText(); canvas.SetFontAndSize(bf, 12); canvas.ShowTextAligned(PdfContentByte.ALIGN_CENTER, '"' + "When printed, this documents are considered uncontrolled" + '"', 300.7f, 10.7f, 0); canvas.EndText(); cb.EndLayer(); } } } #endregion return valid; }

2) And this code i call when delete detail data from one page together.

public ActionResult Delete(string parm) { TableEDIS data = db.TableEDISs.FirstOrDefault(e => e.detail_guid_edis == new Guid(parm)); string fisikFile = data.upload_document; string fisikFileFormulir = data.upload_document_formulir; if (!string.IsNullOrEmpty(fisikFile)) { var relativePath = "~/Content/" + fisikFile; var absolutePath = HttpContext.Server.MapPath(relativePath); var absolutePathOriginal = HttpContext.Server.MapPath(relativePath.Replace("Temporary", "Original")); if (Directory.Exists(Path.GetDirectoryName(absolutePath))) { System.IO.File.Delete(absolutePath); } if (Directory.Exists(Path.GetDirectoryName(absolutePathOriginal))) { System.IO.File.Delete(absolutePathOriginal); } } }

I hope you understand what I mean.

Thanks in advance.
