Convert query expression to dot notation

I want to convert these two query expressio开发者_开发知识库n into dot notation

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);

How to do?

This is untested, but please see if this produces correct results for you -

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

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