IEnumerable to string

I have a DataTable that returns

IDs
,1
,2
,3
,4
,5
,100
,101

I want to convert this to single string value, i.e:

,1,2,3,4,5,100         


        

Answer 1

Try this:

var _values = _tbl.AsEnumerable().Select(x => x);
string valueString = _values.ToList().Aggregate((a, b) => a + b);
