IO operation (C #)

IO operation (C #)
In some games, some parameters are usually written in the configuration, such as XML, EXCEL, TXT, BIN ...... I believe one of them will be used. First, XML and BIN are easy to configure incorrectly for planners. If you can use a program to convert the data in Excel into Txt, Bin, and Xml data, it will be nice. I have written about Excel Data in the previous blog posts. I/O operations are involved here. Not to mention that I/O operations are synchronized here. 309
