[Mono-list] code size of each IL instruction?

[Okehee Goh]

 Hello,
 I'd like to manipulate CIL codes manually. Each instruction's code size
seems to be different.
 Could you tell me where I can refer the code size information for all IL
instructions?
 For instance, the following codes are a part of IL codes generated by using
"monodis" tool.
 The first field implicates a relative address of each instruction and they
are determined by the code size of an ahead instruction. I like to insert
certain IL instructions manually somewhere of these codes.
 So, I'd like to refer the code size of IL instructions.

 Regards,

 Okehee
