aspose文件插入签名

文件在审核批准后，喜欢加入审核人的名子和日期

//原文件中插入书签来定位
Document doc = new Document(sourceFileName);
                    DocumentBuilder builder = new DocumentBuilder(doc);
                    builder.MoveToBookmark("docauthor");
                    builder.Write("王小二");
                    builder.MoveToBookmark("sigdate");
                    builder.Write(DateTime.Now.ToString("yyyy-MM-dd"));

// 通过excel单元格来定位
Aspose.Cells.Workbook workbook = new Workbook(stream);
                    Worksheet sheet = workbook.Worksheets[0];

                    Cells cells = sheet.Cells;
                    cells[5, 8].PutValue("王二小");
                    cells[6, 8].PutValue(DateTime.Now.ToString("yyyy-MM-dd"));
