Return maximum list of list in Entity Framework C# -

i have these 2 classes :

public class result {     public string plate { get; set; }     public double confidence { get; set; }     public int matches_template { get; set; }     public int plate_index { get; set; }     public string region { get; set; }     public int region_confidence { get; set; }     public long processing_time_ms { get; set; }     public int requested_topn { get; set; }     public list<coordinate> coordinates { get; set; }     public list<candidate> candidates { get; set; } }  public class candidate {     public string plate { get; set; }     public double confidence { get; set; }     public int matches_template { get; set; } } 

i have query :

list<list<candidate>> lstcandidates =                     deserializedproduct.results.select(i=>i.candidates).tolist(); 

as can see have list of list<candidate>. every candidate has plate , confidence. need plate number maximum confidence in lstcandidates. how can value?

you can use selectmany orderby , use first methods.

var candidate = deserializedproduct                     .results                     .selectmany(i=>i.candidates) // flatten collection                     .orderbydescending(p => p.confidence) // order descending on confidence property                      .first(); // take max
