unity3d导出pdf

unity生成pdf格式,首先需要导入iTextSharp.dll ,下面是我写的一些方法,可以直接用.直接贴代码,

using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using System.IO;
using iTextSharp.text.pdf;
using iTextSharp.text;
using System.Text.RegularExpressions;
using System.Data.OracleClient;
using System;

//需要用到的数据结构

    public string cvsLevel;    
    public string writeTime;    
    public string creater;      
    public string creatTime;   
};
//数据结构
public  class PdfInformation
{
	public string mID;
	public string mName;
	public string mReserve; 
	//  ....
};

public class PDFMakerManager  {
	
	public static PDFMakerManager PDFInstance;
	public static PDFMakerManager createPDFMakerManager()
	{
		if(PDFInstance==null)
		{
			PDFInstance = new PDFMakerManager ();
		}
		
		return PDFInstance;
	}
	
	//获取物品的子物体名字 通过子物体的名字获取物体  返回物体的链表
    public List<PdfInformation> getObjChildsName(Transform mParentObj) 
    {
       
        if(mParentObj!=null)
        {
            List<string> mChildObjs = new List<string>();
            List<PdfInformation> mInfoList = new List<PdfInformation>();
            foreach (Transform mChildTransform in mParentObj)
            {
                mChildObjs.Add(mChildTransform.gameObject.name);
                Debug.Log(mChildTransform.gameObject.name);
            }
            //获取  数据库  信息
            getPdfDatasFromDB();
            //通过子物体的名字 获取物体信息
            for (int i = 0; i < mChildObjs.Count; i++)
            {
