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 class PdfUserInformation
{
public string goodsName;
public string youzhanType;
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)
{

foreach (Transform mChildTransform in mParentObj)
{

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++)
{
mInfoList.Add(mDirectoryData[mChildObjs[i]]);
}
return mInfoList;
}
return null;
}
