archive.WriteEntry(entry, true);

if (archive != null)
{
archive.Close();
}

outTmpStream.Close();
outStream.Close();

return true;
}

生成 *.tar.gz 文件

生成 *.tar文件（针对文件夹）

for (int i = 0; i < listFilesPath.Count; i++)
{
string fileName = listFilesPath[i];
TarEntry entry = TarEntry.CreateEntryFromFile(fileName);//将文件写到.tar文件中去
archive.WriteEntry(entry, true);
}

if (archive != null)
{
archive.Close();
}

outStream.Close();

生成tar文件（针对于多个文件）

if (directoryName != String.Empty)
Directory.CreateDirectory(strUnpackDir + directoryName);

if (fileName != String.Empty)
{
FileStream streamWriter = File.Create(strUnpackDir + theEntry.Name);

int size = 2048;
byte[] data = new byte[2048];
while (true)
{
size = s.Read(data, 0, data.Length);
if (size > 0)
{
streamWriter.Write(data, 0, size);
}
else
{
break;
}
}

streamWriter.Close();
}
}
s.Close();
fr.Close();

return true;
}
catch (Exception)

return false;

将文件夹压缩成zip

使用C#自带类库对单个文件进行解压缩（rar）

public void YaSuo()
{
using (FileStream fsRead = File.OpenRead(@"F:\MVC5_Demo\Project4YaSuo\Project4YaSuo\Files\笔记.txt"))
{
//创建写入文件的流
using (FileStream fsWrite = File.OpenWrite(@"F:\MVC5_Demo\Project4YaSuo\Project4YaSuo\Files\yasuo.rar"))
{
//创建压缩流
using (GZipStream zipStream = new GZipStream(fsWrite, CompressionMode.Compress))
{
//每次读取1024byte
byte[] byts = new byte[1024 * 10];
int len = 0;
while ((len = fsRead.Read(byts, 0, byts.Length)) > 0)
{
zipStream.Write(byts, 0, len);//通过压缩流写入文件
}
}
}
}
}

压缩成rar文件

public void JieYa()
{
//读取压缩文件
using (FileStream fsRead = File.OpenRead(@"F:\MVC5_Demo\Project4YaSuo\Project4YaSuo\Files\yasuo.rar"))
{
//创建压缩流
using (GZipStream gzipStream = new GZipStream(fsRead, CompressionMode.Decompress))
{
using (FileStream fsWrite = File.OpenWrite(@"F:\MVC5_Demo\Project4YaSuo\Project4YaSuo\Files\笔记.txt"))
{
byte[] byts = new byte[1024 * 10];
int len = 0;
//写入新文件
while ((len = gzipStream.Read(byts, 0, byts.Length)) > 0)
{
fsWrite.Write(byts, 0, len);
}
}

}
}
}
