命令：de4dot.exe "D:\xxx.exe"
解释：运行后文件在程序集的目录下生成一个带-cleaned的新程序集。
命令：de4dot.exe file1 -f "D:\xxx.exe" -o "D:\output\xxx_cleaned.exe"
解释：-f : 指定.NET 程序集文件，-o : 指定输出 文件
命令：de4dot -r "D:\input" -ru -ro "D:\output"
解释：反混淆整个文件夹其中-r xxx : 指定输入文件夹，包括子文件夹，-ru : 跳过不支持的混淆工具混淆过的文件，-ro : 指定输出文件夹
命令：de4dot.exe -f "D:\a\xxx.exe" -d
解释：检测混淆工具名称
命令：de4dot file1.dll -p sa
解释：指定混淆工具名称，de4dot可能检测不准确混淆工具的名称，可以通过 -p 参数指定更多命令：
de4dot <options> <file options>

String decrypter types
none Don't decrypt strings
default Use default string decrypter type (usually static)
static Use static string decrypter if available
delegate Use a delegate to call the real string decrypter
emulate Call real string decrypter and emulate certain instructions
Multiple regexes can be used if separated by '&'.
Use '!' if you want to invert the regex. Example: !^[a-z\d]{1,2}$&!^[A-Z]_\d+$&^[\w.]+$
Examples:
de4dot -r c:\my\files -ro c:\my\output
de4dot file1 file2 file3
de4dot file1 -f file2 -o file2.out -f file3 -o file3.out
de4dot file1 --strtyp delegate --strtok 06000123
