[LINQ運用實例]SelectMany使用情境

(1)扁平化的功能：
     ex. 將二維陣列 轉成 一維


String[][] names = {
new []{"tony"},
new []{"peggy","alex"},
new []{"richie","annie"}
};

var result = names.SelectMany( name => name);

//這邊的 result 將會是  { "tony", "peggy", "alex", "richie","annie"}
foreach(var r in result){
    Console.WriteLine(r);
                }
