篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了cad.net 读取pc3,pmp 读取pc3打印机文件相关的知识，希望对你有一定的参考价值。
修改pc3文件还没做好..大家先look look怎么读....
首先弄一个控制台程序,
然后去下载 Ionic.Zip 这个东西...载到控制台...都很简单...
然后就是复制下面代码,看控制台显示和代码注释....
namespace ConsoleApp1 { class Program { static void Main() { string pc3Path = @"D:\\桌面\\DWG To PDF.pc3"; //cad2008的东西 Pc3PmpDecompress(pc3Path, pc3Path + ".txt"); //解压 } /// <summary> /// 解压pc3和pmp打印机文件 /// </summary> /// <param name="pc3OrPmpPath">打印机路径</param> /// <param name="txtPathOut">输出txt路径</param> public static void Pc3PmpDecompress(string pc3OrPmpPath, string txtPathOut) { using (FileStream fs = File.Open(pc3OrPmpPath, FileMode.Open, FileAccess.ReadWrite)) { //版本信息 int ver1 = 48; { byte[] buffer = new byte[ver1]; fs.Read(buffer, 0, ver1); string str = Encoding.Default.GetString(buffer); Console.Write(Environment.NewLine + "版本信息:" + Environment.NewLine + str); } //12字节=3个int，第一个记录 "校验和" "adler"方式 int ver2 = 4; { //"校验和"读取 byte[] checkSum = new byte[ver2]; fs.Read(checkSum, 0, ver2); //转为16进制再读 var ss = new List<string>(); for (int index = 0; index < checkSum.Length; index++) { var shiliu = ((int)checkSum[index]).ToString("X2"); ss.Add(shiliu); } Console.Write(Environment.NewLine + "压缩校验和:" + Environment.NewLine + string.Join(" ", ss.ToArray())); } int ver3 = 8; { //第二个是原始数据的字节数 //第三个是压缩后的字节数 BinaryReader br = new BinaryReader(fs); var ss = new int[2]; for (int i = 0; i < 2; i++) { ss[i] = br.ReadInt32(); } Console.Write(Environment.NewLine + "原始数据的字节数:" + Environment.NewLine + ss[0].ToString()); Console.Write(Environment.NewLine + "压缩后的字节数:" + Environment.NewLine + ss[1].ToString()); } int ver4 = ver1 + ver2 + ver3; //前面头信息不能解压 fs.Seek(ver4, SeekOrigin.Begin);//从新设置开始的位置,但是不设置也会自动读到这里 using (ZlibStream zs = new ZlibStream(fs, CompressionMode.Decompress))//zip流,解压 { using (StreamReader sr = new StreamReader(zs, Encoding.Default))//流读取器 乱码原因 { string str = sr.ReadToEnd(); //读到结束 using (FileStream fs_out = File.Open(txtPathOut, FileMode.Create, FileAccess.ReadWrite))//新建文本 { byte[] bys = Encoding.Default.GetBytes(str); var lenhth = Encoding.Default.GetBytes(str).Length; fs_out.Write(bys, 0, lenhth);//写入读取的信息 } Console.Write(Environment.NewLine + "压缩包内容:" + Environment.NewLine + str); } zs.Dispose(); } fs.Dispose(); } Console.ReadKey(); } } }
特别感谢的是找到方法的疯狂青蛙: http://www.cnblogs.com/cadlife
和不厌其烦教我怎么读16进制的e大: https://www.cnblogs.com/edata
然后是瞎几把翻译,原因是我还没读透这些东西....部分?号可能是乱码,具体还没设置好
