CIL opcode is for internal logic class or method will be described and the operation of the code, such as Add (add two values to calculate the results pushed on the stack), Ldarg (the argument (referenced sao carlos agora by the specified index value) is loaded into the on the stack) Ldloc.0 (to load a local variable index 0 to calculate the stack), etc. which are divided into the following five categories of operations :( data) push (ld), pop (st), operation, transfer, other ,
Shorthand table below we can easily remember CIL instructions: For example, we know that a ldloc.0 = ld (load) + loc (local) + 0 (0 position parameter) = 0 local variable load index. to the computing stack.
