array<String^>^ query = gcnew array<String^>(4);

query[0] = "/app1/ifd/tiff:";
query[1] = "/app1/ifd/tiff/subifd:";
query[2] = "/ifd/tiff:";
query[3] = "/ifd/tiff/subifd:";

for each (String^ SetQuery in query)
{
 metaData->RemoveQuery(SetQuery + "{uint=256}");
 metaData->RemoveQuery(SetQuery + "{uint=257}");
 metaData->RemoveQuery(SetQuery + "{uint=258}");
 metaData->RemoveQuery(SetQuery + "{uint=259}");
 metaData->RemoveQuery(SetQuery + "{uint=273}");
 metaData->RemoveQuery(SetQuery + "{uint=262}");
 metaData->RemoveQuery(SetQuery + "{uint=277}");

Would ExifTool by Phil Harvey at http://www.sno.phy.queensu.ca/~phil/exiftool/ help you? The Perl source is available if you need to see how it is done.
