轉換查詢表達式爲點記號

Question

我想這兩個查詢表達式轉換成點符號

Q1

var x = from tbl in Person.Get(2, cat.Count) 
     group cat[i] by i/10; 

Q2

foreach(var a in x) 
    string.Split("-", a); 

怎麼辦？

Answer 1

這是未經測試，但請看看這會產生正確的結果你 -

var catList = Person.Get(2, cat.Count); 
catList.GroupBy(c => catList.Indexof(c)/10).Select(a => a.Split("-", a)) 

Answer 2

IEnumerable<string[]> result = (from tbl in Person.Get(2, cat.Count) 
         group cat[i] by i/10).Select(x=>x.Split('-'));
