c# - C# .NET GZipStream 返回不一致的文件长度

Question

我注意到每次我通过GZipStream文件大小运行相同的文件时都会有所不同。当我通过 Windows 资源管理器查看文件时，它size是不同的，但Size on disk始终是相同的。这是预期的行为。

Answer 1

Is your file small? Usually with smaller files the OS may add some padding to the file to make it fill a cluster/block so you'll notice the size may be slightly different. This is much more noticeable on smaller files than larger ones.
