System.Type.GetType does not work in release build.

We recently upgraded our game from Unity 2019 LTS to 2021 LTS and came across a bug that only occurs in our game build (IL2CPP), not in Unity editor.

I have the following code structure as example:

Code (CSharp):

1. public class Character {
2.     public enum MovementType {
3.     }
4. }
5.  
6. public class CrimsonDervish_Toreign_CombatMode {
7.     public class FinalFight {
8.         public class Character {
9.         }
10.     }
11. }
12.  

The problem is System.Type.GetType("Character") will return any Nested class named Character instead of global::Character.

Examples:

Code (CSharp):

1.  
2. // This returns "Character, Assembly-CSharp, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null" which is correct
3. string characterClassTypeName = typeof(global::Character).AssemblyQualifiedName;
4.  
5. // This will return the type CrimsonDervish_Toreign_CombatMode.FinalFight.Character and NOT global::Character like I would expect
6. System.Type.GetType(characterClassTypeName);
7. // Same with this
8. System.Type.GetType("Character");
9. // This returns null instead of the nested type Character.MovementType
10. System.Type.GetType("Character+MovementType");
11. // Same with this
12. System.Type.GetType(typeof(Character.MovementType).AssemblyQualifiedName);

This issue does not occur in unity editor or in 2019 TLS (build and editor), only in 2021 TLS IL2CPP build.
What is the correct way to get the type global::Character from a string?

 

After more tests I am pretty confident this is a new IL2CPP bug.

 

I did more search and it seems this bug has already been reported here and fixed in 2021.3.7. I will test again when this version comes out.

 

Glad it's already fixed, thank you Unity team!

 

Hello there. On Unity 2021.3.23, this issue still persist, at least in my case.
