Searching with Linq
- by Phil
I have a collection of objects, each with an int Frame property. Given an int, I want to find the object in the collection that has the closest Frame.
Here is what I'm doing so far:
public static void Search(int frameNumber)
{
var differences = (from rec in _records
select new { FrameDiff = Math.Abs(rec.Frame - frameNumber), Record = rec }).OrderBy(x => x.FrameDiff);
var closestRecord = differences.FirstOrDefault().Record;
//continue work...
}
This is great and everything, except there are 200,000 items in my collection and I call this method very frequently. Is there a relatively easy, more efficient way to do this?
