title: How do I convert an IntPtr to a Stream?
body: <pre><code>class Foo
  {
     static bool Bar(Stream^ stream);
  };
  
  class FooWrapper
  {
     bool Bar(LPCWSTR szUnicodeString)
     {
         return Foo::Bar(??);
     }
  };
  </code></pre>
  
  <p><code>MemoryStream</code> will take a <code>byte[]</code> but I'd <em>like</em> to do this without copying the data if possible.</p>
