///<returns></returns>
publicstaticstringCompress(stringinput)
{
byte[]inputBytes=Encoding.Default.GetBytes(input);
byte[]result=Compress(inputBytes);
returnConvert.ToBase64String(result);
}

}

3、压缩文件

///<summary>
///压缩目录
///</summary>
///<paramname="dir"></param>
publicstaticvoidCompress(DirectoryInfodir)
{
foreach(FileInfofileToCompressindir.GetFiles())
{
Compress(fileToCompress);
}
}
///<summary>
///解压缩目录
///</summary>
///<paramname="dir"></param>
publicstaticvoidDecompress(DirectoryInfodir)
{
foreach(FileInfofileToCompressindir.GetFiles())
{
Decompress(fileToCompress);
}
}
///<summary>
///压缩文件
///</summary>
///<paramname="fileToCompress"></param>
publicstaticvoidCompress(FileInfofileToCompress)
{
using(FileStreamoriginalFileStream=fileToCompress.OpenRead())
{
if((File.GetAttributes(fileToCompress.FullName)&FileAttributes.Hidden)!=FileAttributes.Hidden&fileToCompress.Extension!=".gz")
{
using(FileStreamcompressedFileStream=File.Create(fileToCompress.FullName+".gz"))
{
using(GZipStreamcompressionStream=newGZipStream(compressedFileStream,CompressionMode.Compress))
{
originalFileStream.CopyTo(compressionStream);
}
}
}
}
}
///<summary>
///解压缩文件
///</summary>
///<paramname="fileToDecompress"></param>
publicstaticvoidDecompress(FileInfofileToDecompress)
{
using(FileStreamoriginalFileStream=fileToDecompress.OpenRead())
{
stringcurrentFileName=fileToDecompress.FullName;
stringnewFileName=currentFileName.Remove(currentFileName.Length-fileToDecompress.Extension.Length);

using(FileStreamdecompressedFileStream=File.Create(newFileName))
{
using(GZipStreamdecompressionStream=newGZipStream(originalFileStream,CompressionMode.Decompress))
{
decompressionStream.CopyTo(decompressedFileStream);
}
}
}
}

二、开源组件ICSharpCode.SharpZipLib进行压缩

///<summary>
///压缩
///</summary>
///<paramname="input"></param>
///<returns></returns>
publicstaticstringCompress(stringinput)
{
stringresult=string.Empty;
byte[]buffer=Encoding.UTF8.GetBytes(input);
using(MemoryStreamoutputStream=newMemoryStream())
{
using(BZip2OutputStreamzipStream=newBZip2OutputStream(outputStream))
{
zipStream.Write(buffer,0,buffer.Length);
zipStream.Close();
}
returnConvert.ToBase64String(outputStream.ToArray());
}
}
///<summary>
///解压缩
///</summary>
///<paramname="input"></param>
///<returns></returns>
publicstaticstringDecompress(stringinput)
{
stringresult=string.Empty;
byte[]buffer=Convert.FromBase64String(input);
using(StreaminputStream=newMemoryStream(buffer))
{
BZip2InputStreamzipStream=newBZip2InputStream(inputStream);

using(StreamReaderreader=newStreamReader(zipStream,Encoding.UTF8))
{
//输出
result=reader.ReadToEnd();
}
}

returnresult;
}
