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CreateTrainingThree 就可以创建PDF了

//分别传入两个表格的数据public void CreateTrainingThree(List tableData1, List tableData2, List tableData3, List 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);}/// 
/// 操作规程/// 
/// void RegulationThree(Report report){report.AddContent(@"3333333333333", report.contentFont);}void SetReportTableThree1(List data){List tabeList = new List {@"标题 ", "序号","时间","1", "2","3","4","5","6","7","8","9","10","11","12","13","14","15","16","17","18","19","20","21","22"};List tabeData = AddTabeData(data,18);for (int i = 0; i < tabeData.Count; i++){//Debug.Log(tabeData[i]);tabeList.Add(tabeData[i]);}tabeArray = tabeList.ToArray();}void SetReportTableThree2(List data){List tabeList = new List {@"大标题 ","序号","时间","1", "2","3","4","5","6","7","8","9","10","11","12","13","14","15","16","17","18","19","20","21","22","23","24","25"};List tabeData = AddTabeData(data,20);for (int i = 0; i < tabeData.Count; i++){//Debug.Log(tabeData[i]);tabeList.Add(tabeData[i]);}tabeArray = tabeList.ToArray();}
