在c＃中添加水印图像

我有这个小代码在doc文件中添加水印图像，只有一点问题，如果我转换一次它工作正常，但如果我尝试转换另一个文件给我这个错误：

RPC服务器不可用。 （来自HRESULT的exception：0x800706BA）

在这一行：

wordFile = oWord.Documents.Open（row.filename）;

这是我的代码：

Microsoft.Office.Interop.Word.Application oWord = new Microsoft.Office.Interop.Word.Application(); Document wordFile = new Document(); //OTHER VARIABLES Object oClassType = "Word.Document.8"; Object oTrue = true; Object oFalse = false; Object oMissing = System.Reflection.Missing.Value; private void BtnInserirImagem_Click(object sender, RoutedEventArgs e) { foreach(MyDocsList row in dataGridList.Items) { wordFile = oWord.Documents.Open(row.filename); addWatermark(wordFile, row.filename); //QUITTING THE APPLICATION oWord.Quit(ref oMissing, ref oMissing, ref oMissing); } } private void addWatermark(Document doc, string filename) { object refmissing = System.Reflection.Missing.Value; string watermarkPath = Directory.GetCurrentDirectory() + "\\fundo.jpg"; if (File.Exists(watermarkPath)) { object linkToFile = false; object saveWithDocument = true; WdHeaderFooterIndex hfIndex = WdHeaderFooterIndex.wdHeaderFooterPrimary; HeaderFooter headerFooter; for (int i = 1; i < doc.Sections.Count + 1; i++) { if (doc.Sections[i].Headers != null) { headerFooter = doc.Sections[i].Headers[hfIndex]; } else if (doc.Sections[i].Footers != null) { headerFooter = doc.Sections[i].Footers[hfIndex]; } else { headerFooter = null; } if (headerFooter != null) { try { Microsoft.Office.Interop.Word.Shape watermarkShape; watermarkShape = headerFooter.Shapes.AddPicture(watermarkPath, ref linkToFile, ref saveWithDocument, ref refmissing, ref refmissing, ref refmissing, ref refmissing, ref refmissing); watermarkShape.Left = Convert.ToSingle(WdShapePosition.wdShapeLeft); watermarkShape.Top = Convert.ToSingle(WdShapePosition.wdShapeCenter); } catch (System.Runtime.InteropServices.COMException e) { MessageBoxResult result = MessageBox.Show(String.Format("{0} - Error Code = {1}", e.Message, e.ErrorCode)); throw e; } } } oWord.ActiveWindow.View.SeekView = WdSeekView.wdSeekMainDocument; oWord.ActiveWindow.ActivePane.View.Type = Microsoft.Office.Interop.Word.WdViewType.wdPrintView; } else { MessageBoxResult result = MessageBox.Show("Could not find watermark image"); } //THE LOCATION WHERE THE FILE NEEDS TO BE SAVED string outstringFile=""; string pathfile = System.IO.Path.GetDirectoryName(filename); string filenameFile = System.IO.Path.GetFileName(filename); outstringFile = pathfile + "\\OG" + filenameFile; Object oSaveAsFile = (Object)(outstringFile); wordFile.SaveAs(ref oSaveAsFile, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing); //CLOSING THE FILE wordFile.Close(ref oFalse, ref oMissing, ref oMissing); }
