本篇章节讲解C#自定义字符串压缩和解压缩的方法。分享给大家供大家参考。具体如下: class ZipLib { public static string Zip(string value) { //Transform string into byte[] byte[] byteArray = new byte[value.Length]; int indexBA = 0; foreach (char item in value.ToCharArray()) { byteArray[indexBA++] = (byte)item; } //Prepare for compress System.IO.MemoryStream ms = new System.IO.MemoryStream(); System.IO.Compression.GZipStream sw = new System.IO.Compression.GZipStream(ms,System.IO.Compression.CompressionMode.Compress); //Compress sw.Write(byteArray,byteArray.Length); //Close,DO NOT FLUSH cause bytes will go missing... sw.Close(); //Transform byte[] zip data to string byteArray = ms.ToArray(); System.Text.StringBuilder sB = new System.Text.StringBuilder(byteArray.Length); foreach (byte item in byteArray) { sB.Append((char)item); } ms.Close(); sw.Dispose(); ms.Dispose(); return sB.ToString(); } public static string UnZip(string value) { //Transform string into byte[] byte[] byteArray = new byte[value.Length]; int indexBA = 0; foreach (char item in value.ToCharArray()) { byteArray[indexBA++] = (byte)item; } //Prepare for decompress System.IO.MemoryStream ms = new System.IO.MemoryStream(byteArray); System.IO.Compression.GZipStream sr = new System.IO.Compression.GZipStream(ms,System.IO.Compression.CompressionMode.Decompress); //Reset variable to collect uncompressed result byteArray = new byte[byteArray.Length]; //Decompress int rByte = sr.Read(byteArray,byteArray.Length); //Transform byte[] unzip data to string System.Text.StringBuilder sB = new System.Text.StringBuilder(rByte); //Read the number of bytes GZipStream red and do not a for each bytes in //resultByteArray; for (int i = 0; i < rByte; i++) { sB.Append((char)byteArray[i]); } sr.Close(); ms.Close(); sr.Dispose(); ms.Dispose(); return sB.ToString(); } } 代码使用方法: string str_org="aaaaaaaaaabbbbbbbbbbbbcccccccccdddddddd"; string str_comp = ZipLib.Zip(str_org); Console.WriteLine("str_comp:" + str_comp); string str_uncomp = ZipLib.UnZip(str_comp); Console.WriteLine("str_uncomp:" + str_uncomp); Console.ReadLine(); 希望本文所述对大家的C#程序设计有所帮助。 (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
