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 PDF
Aspose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。
使用Aspose.Pdf
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。
常用的命名空间和类库
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。

2 美化PDF样式
根据下面（Spire pdf创建的PDF）图片中的样式，用Aspose.Pdf实现。

2.1 创建测试数据
使用DataTable存储我们自己随机产生的100 （行）* 5（列）的数据，该数据仅作演示使用哈。
/// <summary>
/// 数据表格
/// </summary>
/// <returns></returns>
private static DataTable CreateData()
{
DataTable dt = new DataTable();
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<string> nameList = new List<string>
{
"A", "BB", "CCC", "D",
"E", "F", "G","H","II",
"JJ", "LL", "M"
};
List<string> tempList = new List<string>
{
"dsd", "sdfdgvre", "Hello", "Gilrs",
"Today", "YYYY", "dfgre","GSD","fdgfer",
"Wesd", "DLG", "fsdahfi;o"
};
for (int i = 0; i < 10; i++)
{
for (int j = 0; j < 10; j++)
{
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。
/// <summary>
/// 项目的头
/// </summary>
/// <param name="page"></param>
private static void AddPDFProgramTitle(Page page)
{
Table tab1 = new Table();
tab1.ColumnWidths = "80% 20%";
Aspose.Pdf.Row row1 = tab1.Rows.Add();
row1.Cells.Add("Parameter Settings Report(Program)");
row1.Cells[0].DefaultCellTextState.FontSize = 14;
row1.Cells.Add(DateTime.Now.ToString("yyyy/MM/dd HH:mm:ss"));
row1.Cells[1].DefaultCellTextState.FontSize = 11;
row1.MinRowHeight = 35;
row1.DefaultCellTextState.FontStyle = FontStyles.Bold;
Aspose.Pdf.Row emptyRow1 = tab1.Rows.Add();
emptyRow1.Cells.Add(" ");
emptyRow1.Cells.Add(" ");
emptyRow1.MinRowHeight = 1;
emptyRow1.DefaultCellTextState.FontSize = 7;
emptyRow1.DefaultCellBorder = new BorderInfo(BorderSide.Top, 0.1f);
Aspose.Pdf.Row row2 = tab1.Rows.Add();
row2.Cells.Add("Program (Drive Selected / Connected):");
row2.Cells.Add("");
row2.BackgroundColor = Color.LightCyan;
row2.MinRowHeight = 20;
row2.Cells[0].DefaultCellTextState.FontSize = 12;
row2.DefaultCellTextState.FontStyle = FontStyles.Bold;
Aspose.Pdf.Row row3 = tab1.Rows.Add();
row3.Cells.Add("Drive Type / Model:");
row3.Cells.Add("");
// row3.DefaultCellBorder = new BorderInfo(BorderSide.Bottom, 0.1f);
row3.BackgroundColor = Color.LightCyan;
row3.MinRowHeight = 20;
row3.Cells[0].DefaultCellTextState.FontSize = 13;
Aspose.Pdf.Row emptyRow2 = tab1.Rows.Add();
emptyRow2.Cells.Add("");
emptyRow2.Cells.Add("");
emptyRow2.MinRowHeight = 2;
emptyRow2.DefaultCellBorder = new BorderInfo(BorderSide.Bottom, 0.1f);
Aspose.Pdf.Row row4 = tab1.Rows.Add();
row4.Cells.Add("Project:");
row4.Cells.Add("");
// row4.DefaultCellBorder = new BorderInfo(BorderSide.Bottom, 0.1f);
row4.MinRowHeight = 30;
row4.Cells[0].DefaultCellTextState.FontSize = 12;
row4.Cells[0].DefaultCellTextState.FontStyle = FontStyles.Bold;
Aspose.Pdf.Row emptyRow3 = tab1.Rows.Add();
emptyRow3.Cells.Add("");
emptyRow3.Cells.Add("");
emptyRow3.MinRowHeight = 1;
emptyRow3.DefaultCellBorder = new BorderInfo(BorderSide.Bottom, 0.1f);
Aspose.Pdf.Row row5 = tab1.Rows.Add();
row5.Cells.Add("Information");
row5.Cells.Add("");
row5.MinRowHeight = 80;
row5.Cells[0].DefaultCellTextState.FontSize = 11;
row5.DefaultCellTextState.FontStyle = FontStyles.Bold;
row5.VerticalAlignment = VerticalAlignment.Top;
row5.DefaultCellPadding = new MarginInfo(0,0,0,10);
page.Paragraphs.Add(tab1);
}

小结
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。
