GZipStream写入压缩字节 [英] GZipStream compressed bytes written

问题描述

使用GZipStream时，有没有办法知道写了多少个压缩字节？


例如：


//" buffer"是来自文本文件的数据

//" offset"是0

//计数是100


stream.Write（缓冲区，偏移量，计数）;


这将把压缩数据写入底层数据存储。有没有办法得到这些数据的长度？


注意：我知道你可以使用MemoryStream来获得大小，但效率很低。

你能解释一下吗？我不知道我是否正确......但是我可以解释一下......


" count"是压缩的字节数...

在我的例子中，count是未压缩的大小。因此，100个未压缩的字节传递到流中，但流在将其发送到底层数据源之前压缩它们。我想知道有多少字节被发送到底层源。

查看底层流的大小？

When using a GZipStream, is there any way to know how many compressed bytes were written?

For example:

// "buffer" is data from a text file
// "offset" is 0
// "count" is 100

stream.Write(buffer, offset, count);

This is going to write the compressed data to the underlying data store. Is there any way to get the length of this data?

Note: I know you can use a MemoryStream to get the size but this inefficient.

could you explain more? i dont know whether i got u right... but heres wat i can explain....

"count" is number of bytes compressed...

In my example, "count" was the uncompressed size. So 100 uncompressed bytes pass into the stream, but the stream compresses them before sending it to the underlying data source. I want to know how many bytes are sent to the underlying source.

Look at the underlying stream''s size?
