IL2CPP error for type 'System.String'

I get this error when I build my project for IL2CPP (Mono works fine):

Exception: IL2CPP error for type 'System.String' in assembly 'E:\Projects\MyProject\Temp\StagingArea\Data\Managed\mscorlib.dll'
System.NotSupportedException: IL2CPP does not support attributes with object arguments that are array types.

It is a rather large project, I am sure I need to adjust parts to work with IL2CPP but I cannot find the root problem from the error message. Can anybody help me with that?

 

After some trial and error I found the problem: we are using attributes like that

Code (CSharp):

1. [DefaultValue(new int[2] { 2, 5 })]
2. public int[] Variable { get; set; }

for a yaml serializer. So the first line of the error is totally misleading.

Is it true that IL2CPP does not support attributes like that? Is there any replacement or configuration for IL2CPP so I can use these attributes?

 

Ok thanks. I created a sub class of the Attribute class that defines specific constructors for my usage, like that

Code (CSharp):

1. public class ArrayDefaultValueAttribute : DefaultValueAttribute
2. {
3.     public ArrayDefaultValueAttribute(int[] value) : base((object)value) { }
4.     public ArrayDefaultValueAttribute(float[] value) : base((object)value) { }
5. }
6.  
7. [ArrayDefaultValue(new int[2] { 2, 5 })]
8. public int[] Variable { get; set; }

and this seems to solve the problem. Thanks again!
