the main logic is
var someClass = new SomeClass(); //or other c# initialisation 
someClass.SomeMethod();

SomeMethod() cant be called from no where

Example #1
public class SomeClass : MonoBehaviour { // Fields ... // Properties ... // Methods ... // RVA: 0x100400 Offset: 0x100400 VA: 0x100400 public static SomeClass get_Instance() { } // RVA: 0x100500 Offset: 0x100500 VA: 0x100500 public void SomeMethod() // address 0x100500 // RVA: 0x100600 Offset: 0x100600 VA: 0x100600 public static void SomeStaticMethod() // address 0x100600 ... }  
void* (*SomeClass$$get_Instance)() = (void(*)())getRealOffset(0x100400); void (*SomeClass$$SomeMethod)(void *SomeClass) = (void(*)(void *))getRealOffset(0x100500); void* SomeClassInstance = SomeClass$$get_Instance(); SomeClass$$SomeMethod(SomeClassInstance);  
void (*SomeClass$$SomeStaticMethod)() = (void(*)())getRealOffset(0x100600); SomeClass$$SomeStaticMethod(); Example #2
public class SomeOtherClass : MonoBehaviour { // Fields ... // Properties ... // Methods ... // RVA: 0x100300 Offset: 0x100300 VA: 0x100300 public void InitWithSomeClass(SomeClass someClassInstance) { } ... }  
void* SomeClassInstance = NULL; void (*SomeOtherClass$$InitWithSomeClass_original)(void *SomeOtherClassInstance, void* someClassInstance); void _SomeOtherClass$$InitWithSomeClass_hook(void *SomeOtherClassInstance, void* someClassInstance) { SomeClassInstance = someClassInstance; SomeOtherClass$$InitWithSomeClass_original(SomeOtherClassInstance, someClassInstance); } HOOK(0x100300, _SomeOtherClass$$InitWithSomeClass_hook, SomeOtherClass$$InitWithSomeClass_original);  

// RVA: 0x85A9EC0 Offset: 0x7FE1EC0 VA: 0x85A9EC0 public static bool get_isDebugBuild() { } first that i do - open ida and watch who call this function
or other function that contains Debug
very often u can find the real functions only using this

il2cpp:0000000001616E5C                 LDR             W9, [X8,#0x1A0]

mov w28, 1
str w28,[X8,#0x1A0]

public static int a2day; // 0x1A0 == 1
also exist more easy way - i know thats is on forum exists
named like static bla bla bla dont remember
