[游戏开发]Unity 写出PDF到本地（PC）

首先导入itextsharp.dll(及其依赖)到Plugins文件夹。

其次，看下面代码。

一个写入表格的例子，供学习参考使用：

using System.Collections.Generic;
using System.IO;
using iTextSharp.text;
using iTextSharp.text.pdf;

public static class WritePDFHelper
{
    /// <summary>
    /// 写入PDF
    /// </summary>
    /// <param name="filePath">写入路径(包含文件名称及后缀)</param>
    /// <param name="titleFrontPath">标题字体路径</param>
    /// <param name="textFrontPath">正文</param>
    /// <param name="title">标题内容</param>
    /// <param name="tableContent">表格内容，每一个List元素为一个表格，以每个string[][]二位数组的第一行为限，若超出则不会显示，若不足，应该会报索引超出异常</param>
    /// Demo:
    /// WritePDFG(@"C:\\xxxx\xxx/生成pdf.pdf",
    /// @"c:\windows\fonts\simhei.ttf",
    /// @"c:\windows\fonts\simsun.ttc,1", "xxxxx", new List<string[][]>()
    /// {
    ///     new[] {new[] {"1", "2", "3"}, new[] {"2", "3", "4"}, new[] {"1", "2", "3"}},
    ///     new[] {new[] {"1", "2", "3"}, new[] {"2", "3", "4"}, new[] {"3", "2", "2"}}
    /// });
    public static void WritePDF(string filePath, string titleFrontPath, string textFrontPath, string title, List<string[][]> tableContent)
    {
        Document document = new Document();
        try
        {
            PdfWriter.GetInstance(document, new FileStream(filePath, FileMode.Create));
            document.Open();
            //标题字体
            BaseFont bf_Title = BaseFont.CreateFont(titleFrontPath, BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
            iTextSharp.text.Font font_Title = new iTextSharp.text.Font(bf_Title, 20);

            BaseFont bf_Txt = BaseFont.CreateFont(textFrontPath, BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
            iTextSharp.text.Font font_Txt = new iTextSharp.text.Font(bf_Txt, 12);

            //写标题
            Paragraph paragraph_title = new Paragraph(title, font_Title);
            //标题居中
            paragraph_title.Alignment = Rectangle.ALIGN_CENTER;
            document.Add(paragraph_title);

            //输入一个空行，以分开标题与表格
            Paragraph nullp = new Paragraph(" ", font_Title);
            nullp.Leading = 10;

            //写入内容
            for (int i = 0; i < tableContent.Count; i++)
            {
                document.Add(nullp);
                string[][] piece = tableContent[i];
                PdfPTable piece_Table = new PdfPTable(piece[0].Length);
                for (int j = 0; j < piece.Length; j++)
                {
                    for (int k = 0; k < piece[j].Length; k++)
                    {
                        piece_Table.AddCell(new PdfPCell(new Phrase(piece[j][k], font_Txt)));
                    }
                }

                document.Add(piece_Table);
            }

            document.Close();
        }
        catch (DocumentException de)
        {
            throw de;
        }
        catch (IOException io)
        {
            throw io;
        }
    }
}
