. NET file format related open source projects

For the past 2 years, I have identified the file format as one of my main research topics, and Npoi is the product of such research. Although strictly speaking, Npoi is only the POI. NET version, not I created, but in the development process, I have in-depth understanding and understanding of OLE2, but also the office 97-2003 file format has a very different understanding. If in the past, someone asked me: Do you know the Office file format? As a developer I will not hesitate to say: I certainly know! But now, I would say: I only know part of it. There is a good saying: The more you learn, the more you feel ignorant.

A lot of graduate students to write a qualified paper at graduation, I think 3 years did not learn anything, at best is to follow the tutor to do some of the projects to earn extra money, in fact, they do not realize that many research issues in their eyes, but they do not know to dig it, so someone said: the study of people have nothing to drill dead, To understand the "preoccupied", you think everything is "pleasing to the eye", but also study a what. The file format is valuable because it may involve many algorithms, compression, and coding knowledge, and it can also help you understand the ideas of previous generations-why use this algorithm instead of another; Why use this structure instead of another one.

Well, the prologue is almost, hehe. Start to get to the point, I hope the following content is helpful to everyone, especially to study the file format of friends.
