本文实例讲述了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();
