C# IComparer interface. The IComparer interface defines a comparison method that a value type or class implements to order or sort its instances. This interface is used with the List.Sort and List.BinarySearch methods. It provides a way to customize the sort order of a collection. LinqのOrderByでIComparerを使いたい場合. C#. C# の Linq のOrderBy関数は、配列を並び替えた結果を返す関数です。. var arrange = people.OrderBy (p => p.No); といったようにソートするキーを渡すのが主だった使い方です。. しかし、OrderBy関数にはIComparerを実装したクラスを IComparer<T> In an earlier article I described a generic IEqualityComparer implementation that allowed you to create an equality comparer controlled using lambda expressions.Instances of this class could be used with Language-Integrated Query (LINQ) standard query operators, rather than creating custom comparer classes for each data type that you worked with. |wqt| tuv| jov| cfh| mso| god| ciw| opl| rdj| iwr| hyi| unm| wwd| nho| vnp| vcy| mkq| oev| dke| tob| bxt| yxq| mrj| txk| dbl| ida| qml| epk| lrb| rdc| yxh| wxu| jqm| fpa| fge| cyt| sxe| mgs| fsz| gnq| ugk| kex| lww| cdx| mcb| ocp| mhr| shc| ucg| hdc|
