## README

Sometimes we may want to modify a complied exe/dll without the source code. To archive this, we have 2 options:
1. Modify the file and complie it.
2. Hook at runtime.

For first option, we have several tools for it. 
1. Use ildasm and ilasm
Disassemble the exe by using the following command
ildasm /out=file.il My.exe 
Tweak the IL inside the file.il file
Assemble it back again with
ilasm file.il
2. Use Reflexil plugin in Reflector or JustDecomplier. It support to edit the IL and save the assembly file.

For the second option, we can use EasyHook. Refer to below links:

Note: 
1. For strange name assembly, we need sn tool.
2. Can write code then use tools to generate IL code, like LinqPad.
