Uniyt动态生成PDF文件 iTextSharp插件使用

先封装一个创建PDF的类

using iTextSharp.text;
using iTextSharp.text.pdf;
using System.Collections.Generic;
using System.Drawing;
using System.IO;
using UnityEditor;
using UnityEngine;
using Font = iTextSharp.text.Font;
using Image = iTextSharp.text.Image;
using Rectangle = iTextSharp.text.Rectangle;public class Report

}

实例PDF

再创建一个类 吧下面的代码粘贴进去 然后调用 就可以创建PDF了

//分别传入两个表格的数据public void CreateTrainingThree(List<string> tableData1, List<string> tableData2, List<string> tableData3, List<string> tableData4){Document document = new Document(PageSize.A3, 30, 30, 5, 5);Report report = new Report("大标题", document);currentTime = System.DateTime.Now;report.AddContent("大标题", report.titleFont, 1);report.Space();report.AddContent("姓 名：                         	          ", report.contentFont);report.Space();report.AddContent("一、 ", report.secondTitleFont);report.Space();PurposeThree(report);report.Space();report.AddContent("二、 ", report.secondTitleFont);report.Space();TaskThree(report);report.Space();report.AddContent("三、", report.secondTitleFont);report.Space();RegulationThree(report);report.Space();report.AddContent("四、表格", report.secondTitleFont);report.Space();SetReportTableThree1(tableData1);report.AddTableTrainingThree(19, tabeArray);report.Space();report.Space();SetReportTableThree2(tableData2);report.AddTableTrainingThree2(21, tabeArray);report.ClosePDF();}void PurposeThree(Report report){report.AddContent(@"1111111111", report.contentFont);}/// 
/// 实训任务/// /// void TaskThree(Report report){report.AddContent(@"22222222222", report.contentFont);}///
