Given the code below, how do I compare a List of objects's values with a test value?
I'm building a geolocation application. I'll be passing in longitude and latitude and would like to have the service answer back with the location closest to those values.
I started down the path of converting to a string, and formatting the values down to two decimal places, but that seemed a bit too ghetto, and I'm looking for a more elegant solution.
public class Location : IEnumerable
{
public string label { get; set; }
public double lat { get; set; }
public double lon { get; set; }
//Implement IEnumerable
public IEnumerator GetEnumerator()
{
return (IEnumerator)this;
}
}
[HandleError]
public class HomeController : Controller
{
private List<Location> myList = new List<Location>
{
new Location {
label="Atlanta Midtown",
lon=33.657674,
lat=-84.423130},
new Location {
label="Atlanta Airport",
lon=33.794151,
lat=-84.387228},
new Location {
label="Stamford, CT",
lon=41.053758,
lat=-73.530979}, ...
}
public static int Main(String[] args)
{
string inLat = "-80.987654";
double dblInLat = double.Parse(inLat);
// here's where I would like to find the closest location to the inLat
// once I figure out this, I'll implement the Longitude, and I'll be set
}
