Pointer problems... Marshal.Copy Vector3[,,] Array to Byte[] Array

Hi everyone,

I'm trying to Marshal.Copy a Vector3[,,] array to a Byte[] array. But that seem lite ugly.

Code (CSharp):

1.  // Create a managed array.
2. Vector3[,,] managedArray = new Vector3[10,10,10];
3.  
4. // Get the sise and and create a byte array
5. int size = Marshal.SizeOf(managedArray[0,0,0]) * managedArray.Length;
6.  
7. // Allocate memory
8. IntPtr pnt = Marshal.AllocHGlobal(size);
9.  
10. //// But an error occur : Can not convert Unity.Engine Vector3[,,] to byte[]
11. Marshal.Copy(managedArray, 0, pnt, managedArray.Length);

Does Marshal.Copy works with one dimensional arrays only?
Is there any other solution to achieve this?

Thank you..

 

You should be able to Marshal Vector3 to C++ by using a struct. And you can also Marshal a matrix.
Examples are here: https://docs.microsoft.com/de-de/dotnet/framework/interop/marshalling-different-types-of-arrays
