(1) SOLID Rars are only supported in the RarReader API. 

(2) Zip format supports pkware and WinzipAES encryption. However, encrypted LZMA is not supported. 

(3) The Tar format requires a file size in the header. If no size is specified to the TarWriter and the stream is not seekable, then an exception will be thrown. 

(4) The 7Zip format doesn't allow for reading as a forward-only stream so 7Zip is only supported through the Archive API。

    也支持流方式的压缩和解压：

GZipStream

DeflateStream
