如何解压缩.gz文件并使用c#将文件保存在特定文件夹中？
这是我第一次遇到.gz文件.我已经在搜索如何解压缩但它对我不起作用.它没有解压缩特定文件夹中的.gz文件.我不想使用任何第三方应用程序.
任何人都可以给我一个如何解压缩它的示例代码.然后将文件保存在文件夹中.谢谢.
解决方法
以下来自
MSDN的示例显示了如何使用GZipStream类压缩和解压缩文件目录.
namespace zip
{
public class Program
{
public static void Main()
{
string directoryPath = @"c:\users\public\reports";
DirectoryInfo directorySelected = new DirectoryInfo(directoryPath);
foreach (FileInfo filetoCompress in directorySelected.GetFiles())
{
Compress(filetoCompress);
}
foreach (FileInfo filetoDecompress in directorySelected.GetFiles("*.gz"))
{
Decompress(filetoDecompress);
}
}
public static void Compress(FileInfo filetoCompress)
{
using (FileStream originalFileStream = filetoCompress.OpenRead())
{
if ((File.GetAttributes(filetoCompress.FullName) & FileAttributes.Hidden) != FileAttributes.Hidden & filetoCompress.Extension != ".gz")
{
using (FileStream compressedFileStream = File.Create(filetoCompress.FullName + ".gz"))
{
using (GZipStream compressionStream = new GZipStream(compressedFileStream,CompressionMode.Compress))
{
originalFileStream.copyTo(compressionStream);
Console.WriteLine("Compressed {0} from {1} to {2} bytes.",filetoCompress.Name,filetoCompress.Length.ToString(),compressedFileStream.Length.ToString());
}
}
}
}
}
public static void Decompress(FileInfo filetoDecompress)
{
using (FileStream originalFileStream = filetoDecompress.OpenRead())
{
string currentFileName = filetoDecompress.FullName;
string newFileName = currentFileName.Remove(currentFileName.Length - filetoDecompress.Extension.Length);
using (FileStream decompressedFileStream = File.Create(newFileName))
{
using (GZipStream decompressionStream = new GZipStream(originalFileStream,CompressionMode.Decompress))
{
decompressionStream.copyTo(decompressedFileStream);
Console.WriteLine("Decompressed: {0}",filetoDecompress.Name);
}
}
}
}
}
}
