这个是我自己做的，感觉效率很低，而且无法查询。
public
IList GetPictureByPTypeID(
string
PTypesID,
int
firstResult,
int
maxResults,
out
int
recordcount)
{
IList plist = pm.PType.Find(int.Parse(PTypesID)).Pictures; recordcount = plist.Count; return IListPage(firstResult, maxResults, plist);
}
public
IList IListPage(
int
firstResult,
int
maxResults, IList list)
{ ArrayList tlist = new ArrayList(); int i = 0; foreach (object obj in list)
{ if (i >= firstResult && i < (firstResult+maxResults)) { tlist.Add(obj);
} i++; } return tlist; }
