Native plugin: How to pass bool[] from C# to plugin in C?

Hi All,
I am writing a plugin in which i have to pass a bool[] from C# to bool* in C. But for some reason native isn't getting data correctly.

If i pass this from C#:

{ true, false, true, true, false };​

then native C gets this

{ true, false, false, false, false };​

My other data types(int, float, double, long arrays) are working fine. Here is my code:
C# (managed):
Declaration

Code (csharp):

1. [DllImport("dll_name_here")]
2. private extern static void Internal_AddBooleanArray(bool[] a_boolArr, int a_arrSize);

Sending data:

Code (csharp):

1. bool[] l_arrBool = { true, false, true, true, false };
2. Internal_AddBooleanArray(l_arrBool, 5);

C (unmanaged):

Code (csharp):

1. void DLL_EXPORT Internal_AddBooleanArray(bool* a_boolArray, int a_lengthOfArray)
2. {
3.         for (size_t l_index = 0; l_index < a_lengthOfArray; l_index++)
4.         {
5.             printf("Main::Bool at index '%d' is '%d':'%s'", l_index, a_boolArray[l_index], (a_boolArray[l_index] ? "true" : "false"));
6.         }
7.  
8. }

From above printf(...) statement i am getting { true, false, false, false, false };

 

I would guess this would suggest that they are different sizes, https://www.dotnetperls.com/bool-array confirms this

 

@nat42, I don't think that's the issue. bool in C and C# is of 1 byte.

 

Might be somewhat enlightening regardless to cast the bools to int and see there values?

 

@nat42 , From my original post, i am already printing values in int as well as in bool using

Code (csharp):

1. printf("Main::Bool at index '%d' is '%d':'%s'", l_index, a_boolArray[l_index], (a_boolArray[l_index] ? "true" : "false"));

Here's my output.
Main::Bool at index '0' is '1':'true'
Main::Bool at index '1' is '0':'false'
Main::Bool at index '2' is '0':'false'
Main::Bool at index '3' is '0':'false'
Main::Bool at index '4' is '0':'false'

 

Any idea guyz?

Thanks @elias_t . I'll try approach from article tonight.
