    public int field3;
}

and I have pointer to

Answer 1

This function worked for me, assuming that the size of the struct is fixed:

public static void MarshalUnmananagedArray2Struct(IntPtr unmanagedArray, int length, out T[] mangagedArray)
{
    var size = Marshal.SizeOf(typeof(T));
    mangagedArray = new T[length];

    for (int i = 0; i < length; i++)
    {
        IntPtr ins = new IntPtr(unmanagedArray.ToInt64() + i * size);
        mangagedArray[i] = Marshal.PtrToStructure(ins);
    }
 }
