我有这个简单的例子(从MSDN文档中复制),但是从未创建.gz文件......
我试图添加对compressedFileStream.Flush()的调用;但没什么......
static string directoryPath = @"C:\\temp\\";
...
public string CompressFile(FileInfo fileToCompress)
{
try
{
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);
compressedFileStream.Flush();
FileInfo info = new FileInfo(directoryPath + "\\" + fileToCompress.Name + ".gz");
return String.Format("Compressed {0} from {1} to {2} bytes.", fileToCompress.Name, fileToCompress.Length.ToString(), info.Length.ToString());
}
}
return "File yet compressed.";
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message, "Error", MessageBoxButton.OK, MessageBoxImage.Error);
}
return "";
}

您的代码运行正常。我只是运行它,我传递了文件的名称,我得到了gzipped文件。请记住,您的gz文件将在与原始文件相同的目录中创建。我看到你有directoryPath变量,并且你正在使用它来读取有关新创建文件的信息。确保directoryPath和您传递的文件位于同一目录中。一种方法是在调用函数时使用directoryPath变量。例如
var result = CompressFile(new FileInfo(directoryPath + "FileToCompress.txt"));
我得到了结果:
压缩FileToCompress.txt,从10920到10个字节。
