How to marshal a dynamic sized array

[Charming12]

Hi All,

This is a problem which is eating my head from several days.

I have a structure which contains an array of elements as


public byte[] pinNumbers;


To use it in my C# class i need to marshall it as

[MarshalAs(Unman agedType.ByValA rray, ArraySubType = UnmanagedType.U 1, SizeConst = 6)]
public byte[] pinNumbers;

But here using this marshalling technique , I was forced to pass a fixed size for the array as SizeConst = 6,
but now i have several arrays which are dynamic arrays whose sizeconst has to be determined at the runtime.

How can i Marshal dynamic arrays using any marshalling technique ?

please provide me with a solution as i have tried a lot to marshal arrays using other marshalling styles as well.

Thanks

Can't you use a constant variable in SizeConst = aContantVariabl e?
P.S By dynamic array you mean ArrayList?

Thanks for replying

yes by dynamic array i mean varaible length array whose size can not be fixed it has to be passed at run time.

passing a const size is not what is required in the program.

Did you ever find a solution for this? I'm trying to do the same thing.
