阅读二进制文件 [英] Reading Binary Files

问题描述

我需要将一个大的二进制文件拆分成两个二进制文件。我在二进制文件中有一个分隔符

（比如NewLine）。我需要拆分二进制文件，使得第一个文件到达NewLine，第二个文件来自NewLine，结束文件的
。请告知我这是否可能


谢谢

I need to split a large binary file into two binary files. I have a delimiter
(say NewLine) in the binaryfile. I need to split the binary file such that
the first file is upto the NewLine and the Second file is from NewLine to end
of file. Kindly let me know whether this si possible

Thanks
Rohith

只需打开一个针对该文件的System.IO.FileStream。通过块[

将它读出来一个byte []并检查你的分隔符的块。把块子

写成第一个然后是一个seconde FileStream。


David

Just open a System.IO.FileStream against the file. Read it out by chunks
into a byte[] and examine the chunks for your delimeter. Write the chunks
to a first and then a seconde FileStream.

David

Ya。这会奏效。但我有一个巨大的二进制文件近1GB。是否有一个

备用解决方案来查找分隔符位置，并检查每个

块通过它循环

Ya..This will work. But I have a huge binary file nearly 1GB. Is there an
alternate solution to find the delimiter position with checking on every
chunk looping through it

对不起，没有循环遍历每一块数据。

Sorry, without looping through every chunk of data.
