Quote:How can I read a file that format is like this C#
With pain, this file is "binary", it mean that this file is meant to be read by computer, not by humans.
First of all you need to understand that the debugger have changed the file to make it more human readable, so trying to match what the debugger display will never work.
Knowing what is in the file may also help to decipher.
The first step is to use a programmer's editor with hexadecimal mode, it will display the exact contain of the file, printable chars or not.
As the filename from picture look to come from a game, you need to know that such file are usually intentionally encoded to make them difficult to decipher in order to avoid unauthorized tempering.
