C# LINQ: How to find IList<Peak>.Max?

I need to find the tallest peaks in a given latitude and longiture. I'm trying to modify this example to work with class Peak but don't understand how to use .Max on IEnumerable<Peak> rather than IEnumerable<double>. The compiler, of course, complains

Operator '==' cannot be applied to operands of type 'double' and 'Peak'

This is my first time using LINQ. How do I find the Max Elevation in IEnumerable<Peak> range?

public class Peak
{
    readonly Double latitude;
    public Double Latitude { get { return latitude; } }
    readonly Double longitude;
    public Double Longitude { get { return longitude; } }
    readonly Double elevation;
    public Double Elevation { get { return elevation; } }
    public Peak(Double latitude, Double longitude, Double elevation)
    {
        this.latitude = latitude;
        this.longitude = longitude;
        this.elevation = elevation;
    }
}
private IList<Peak> FindPeaks(IList<Peak> values, int rangeOfPeaks)
{
    var peaks = new List<Peak>();
    var checksOnEachSide = rangeOfPeaks / 2;
    for (var i = 0; i < values.Count; i++)
    {
        var current = va开发者_如何学Golues[i];
        IEnumerable<Peak> range = values;
        if (i > checksOnEachSide)
            range = range.Skip(i - checksOnEachSide);
        range = range.Take(rangeOfPeaks);
        if (current.Elevation == range.Max())
            peaks.Add(current);
    }
    return peaks;
}

Specify the property you want the maximum of:

if (current.Elevation == range.Max(p => p.Elevation))..

See the Max<Peak> usage to find the max Elevation:

if (current.Elevation == range.Max(p => p.Elevation))
    peaks.Add(current); 

I suggest you to read a little about lambda expressions to better understand how this sintax works.
