In my C++ cli program, I reference a .NET C# DLL and call some APIs inside.
One of the API interface is Byte[], I pass C++Cli Byte array but get an error..
how should I input a byte array to C# API?

Here is my code:

//Here is C++ Cli code:

void PassData(array<Byte>^ ArrayData)
{
    //get compiler error here:
    CSharpDLL.PassData(ArrayData);
    return;
}
