pointer problems

in the following code, the Response.WriteF ile errors saying "Invalid handle"

Response.Clear( );
Response.Conten tType = "applicatio n/octet-stream";
Response.AddHea der("Content-Disposition", "attachment ; filename=" +
aFileName);
unsafe
{
long xSize = email.GetAttach mentSize(xIndex );
long xOffset = 0;

GCHandle h = GCHandle.Alloc( email.GetAttach mentData(xIndex ),
GCHandleType.Pi nned);
Response.WriteF ile(h.AddrOfPin nedObject(),xOf fset,xSize);
h.Free();
}
Response.Flush( );

changing the type of pointer to a different type causes the error: "Handle
is not pinned"

h.AddrOfPinnedO bject() = a long like: 169803832
Question: how do I get Response.WriteF ile to accept the value of
h.AddrOfPinnedO bject() ?

Thank you for your help.
