npoi插入图片 解决无法打开word的问题

我需要重复操作的word 根据对应人物名称插入的不同位置的 单元格，一次只能插入一张图片

/// <summary> /// 导出word /// </summary> /// <param name="fileName">原文件名</param> /// <param name="outPath">输出路径</param> /// <param name="record">要输入数据信息</param> /// <returns></returns> public static bool ExportMeetingRecord(string fileName, string outPath, NpoiTransmitData record) { XWPFDocument doc = null; using (FileStream file = new FileStream(fileName, FileMode.Open, FileAccess.Read)) { doc = new XWPFDocument(file); } try { //遍历表格 var tables = doc.Tables; if (tables == null || tables.Count == 0) { } else { var table = doc.Tables[doc.Tables.Count - 1]; foreach (var row in table.Rows) { List<XWPFTableCell> cells = row.GetTableCells(); for (int i = 0; i < cells.Count; i = i + 2) { XWPFTableCell cell = cells[i]; string text = cell.GetText(); if (!text.Trim().Equals(record.name)) continue; string imagePath = record.value; if (string.IsNullOrEmpty(imagePath)) continue; string picId = string.Empty; using (FileStream imageFileStream = new FileStream(imagePath, FileMode.Open)) { picId = doc.AddPictureData(imageFileStream, (int)NPOI.XWPF.UserModel.PictureType.JPEG); } if (string.IsNullOrEmpty(picId)) continue; //cells[i + 1].SetVerticalAlignment(XWPFTableCell.XWPFVertAlign.CENTER); string imageName = Path.GetFileNameWithoutExtension(imagePath); CreatePicture(cells[i + 1], picId, (uint)i, 64, 64); //CreatePicture2(cells[i + 1], picId, 64, 64); //setCellImage(cells[i + 1], 3 * 256, 6 * 256, imagePath, NPOI.XWPF.UserModel.PictureType.JPEG); } } } FileStream file = new FileStream(outPath, FileMode.Create, FileAccess.Write); doc.Write(file); file.Close(); file.Dispose(); return true; } catch (Exception ex) { throw ex; } }

注意 $"<pic:cNvPr id="{id + 1}" name=“图片 {id + 1}”/>" 与 docPr.id = id+1; docPr.name = "图片 " + (id + 1); 尽量保持一致，以免出现 插入一次图片后 word 文件无法读取的问题。
