Question

How can i aggregate all element in one column to have a string by linq

For example:
I have table named:Items And one column of table named: ListItem

                    ListItem
                      1
                      2
                      3

How can I select all elements in Column ListItem to have string : 123

(Not select each values of column and join together)

Tks for everyone’s help !!!

Answer 1

I think all answers with string.Join are incomplete since this method needs an array of strings, not an IEnumerable.

This should work.

var data = ...
var result = string.Join(" ", data.Select(x => x.ListItem).ToArray());

This results in:

"1 2 3"
