Is calling MemoryStream.ToArray() dangerous after disposing?

In the below code, is there any chance the GC will clean out the MemoryStream so that ToArray will fail, since it is outside the using statement?

private static byte[] getBytes()
{
    MemoryStream ms = null;

    using (ms = new MemoryStream())
    {
        // ...
    }

    return ms.ToArray();
}
