C# unsafe value type array to byte array conversions

Question

I use an extension method to convert float arrays into byte arrays:

public static unsafe byte[] ToByteArray(this float[] floatArray, int count)
{
    int arr         


        

Answer 1

    public byte[] ToByteArray(object o)
    {
        int size = Marshal.SizeOf(o);
        byte[] buffer = new byte[size];
        IntPtr p = Marshal.AllocHGlobal(size);
        try
        {
            Marshal.StructureToPtr(o, p, false);
            Marshal.Copy(p, buffer, 0, size);
        }
        finally
        {
            Marshal.FreeHGlobal(p);
        }
        return buffer;
    }

this may help you to convert an object to a byte array.
