前言
项目中需要将数据导出存为PDF格式，试了一下Aspose组件，仅以此记录一下使用感受。 关于Aspose PDFAspose于2002年3月在澳大利亚悉尼创建，一直致力于成为全球最大的.NET组件提供商。 Aspose.Pdf是一个PDF文档创建组件，可以帮助用户无需使用Adobe Acrobat即可读写和操作PDF文件。Aspose.Pdf功能丰富：有PDF文档压缩选项，表格创建与操作，插入图表、图像功能，丰富的超链接功能，图章和水印任务，扩展的安全性组件以及自定义字体处理。 Aspose.PDF for .NET支持流行的文件格式，例如PDF，XFA，TXT，HTML,PCL,XPS,EPUB,TEX和图像格式，并允许直接通过API或XML模板创建PDF文档，并且可以创建表单或管理文档中嵌入的表单字段。 Aspose的组件是收费的，但是网上也能收到很多破解版本，且去掉页眉和水印之类的限制。 使用Aspose.Pdf组件时，常用的命名空间和类库如下，可根据自己的实际需求增添： 命名空间： using Aspose.Pdf; using Aspose.Pdf.Devices; using Aspose.Pdf.Text; using Aspose.Cells; 类 说明Aspose.Pdf.Document PDF文档Aspose.Pdf.Page PDF页面Aspose.Pdf.HeaderFooter 页眉页脚Aspose.Pdf.MarginInfo 页边距Aspose.Pdf.Table 表格Aspose.Pdf.Row 行Aspose.Pdf.TextFragment 文本段落 1 创建简单的PDF文档创建一个带页眉页脚的PDF文档Document 。首先是创建HeaderFooter 页眉页脚，然后在页眉页脚中插入Table 表格，在表格的行中单元中填充TextFragment 文本段落。Page 页面内容也是一样的套路。 /// /// 创建简单PDF /// public static void CreatePdf1() {//Evaluation Only.

DataColumn col1 = new DataColumn("Num", typeof(string)); DataColumn col2 = new DataColumn("Name", typeof(string)); DataColumn col3 = new DataColumn("Val", typeof(string)); DataColumn col4 = new DataColumn("Des", typeof(string)); DataColumn col5 = new DataColumn("Set", typeof(string)); dt.Columns.Add(col1); dt.Columns.Add(col2); dt.Columns.Add(col3); dt.Columns.Add(col4); dt.Columns.Add(col5); Random random = new Random(); List nameList = new List { "A", "BB", "CCC", "D", "E", "F", "G","H","II", "JJ", "LL", "M" }; List tempList = new List { "dsd", "sdfdgvre", "Hello", "Gilrs", "Today", "YYYY", "dfgre","GSD","fdgfer", "Wesd", "DLG", "fsdahfi;o" }; for (int i = 0; i DataRow dr = dt.NewRow(); dr[0] = "KK" + i.ToString("d2") + "." + j.ToString("d2"); dr[1] = nameList[j]; if (j % 3 == 0) { dr[2] = random.NextDouble().ToString("f3"); } else { dr[2] = i * j - random.Next(0, 30); } dr[3] = tempList[j]; dr[4] = random.NextDouble().ToString("f2"); //添加新行 dt.Rows.Add(dr); } } return dt; } 2.2 项目头部样式设计一下项目头部样式，这里是使用单独函数实现的，后面调用就可以了。 实际上是一个表格，表格中有5行，设置行高、单元格内容以及单元格样式，就可以实现了。最后将表格添加到Page的段落中即可。 将测试数据，项目头部信息，以及数据内容全部整合在一起，生成PDF。 /// /// 制作Aspose PDF /// /// /// public static void MakeAsposePDF() { //获取测试数据 DataTable dataTable = CreateData();

}效果： Aspose.Pdf很容易上手，都是面向对象编程，想要什么就创建相应的实体类即可。不过需要自己找破解版的资源，破解版可能也不是当前最新版本。 相比c# 数据保存为PDF （spire pdf篇） Spire.PDF 还是Aspose.Pdf更简单容易上手。 附录参考1、c# 数据保存为PDF （spire pdf篇）https://blog.csdn.net/weixin_40314351/article/details/130406659?spm=1001.2014.3001.5501 2、Aspose.PDF for .NET相关案例使用Demo https://www.evget.com/product/565/resource 3、Aspose.Pdf官网 https://releases.aspose.com/pdf/ |
