将数据写入Word模版,生成PDF并加水印

需要引用,DLL请自行下载

using Aspose.Pdf;
using Aspose.Words;
using System.Data;
using System.IO;

首选创建Word数据模版;使用Office或者WPS创建一个DOC模版,并增加域;如何增加域名可自行搜索

WPS增加 使邮件合并

 

然后制做出以下类似模版

 

 

关于输出列表;需要使用 域 

 

将你要循环输出的字段包住

 

 

//这里获取Table数据源,表的列名需要与模版中的域名对应
            DataTable dt = new DataTable();
            //这里获取列表数据的数据源;表的列名也需要与域名对应
            DataTable dtlist = new DataTable();

            //建议列表数据列最好不要与单一数据的表存在相同的列名称
            string _templatePath = "template.doc"; //模板路径
            _templatePath = Server.MapPath(_templatePath);
            string _savePath = "/out/"; //保存生成文档路径
            string sp = Server.MapPath(_savePath);
            string f = Guid.NewGuid().ToString("N") + ".doc";
            string copyto = sp + f;

            File.Copy(_templatePath.ToString(), copyto, true); //将文件复制到结果文档中
            Aspose.Words.Document doc = new Aspose.Words.Document(copyto);
            Aspose.Words.DocumentBuilder builder = new DocumentBuilder(doc);
            //先进行列表数据的替换,注意DataTable.TableName属性要与 «TableStart:s2198» 域名保持一致
            doc.MailMerge.ExecuteWithRegions(dtlist);


            foreach (DataRow r in dt.Rows)
            {
                //这里获取列名,请注意更改为自己获取列名的逻辑
                string field = string.Format("s{0}", r["itemid"].ToString());//
                while (builder.MoveToMergeField(field))
                {
                    builder.Write(r["value"].ToString());//写入值
                }
            }

            //到此,往WORD模版里写入数据的逻辑就已经完成,接下来将数据保存为PDF

            MemoryStream docStream = new MemoryStream();

            //imageStamp.Height = 350;
            //imageStamp.Width = 350;
            imageStamp.Opacity = 0.5;
            //水印位置
            imageStamp.HorizontalAlignment = HorizontalAlignment.Center;
            imageStamp.VerticalAlignment = VerticalAlignment.Center;

            for (int j = 1; j <= pdfDocument.Pages.Count; j++)
            {
                pdfDocument.Pages[j].AddStamp(imageStamp);
            }
            //保存PDF
            pdfDocument.Save(docStream);
