_comboBoxItems is array
[0] = "01 01010304"
[1] = "01 01230304"
[2] = "01 01010784"
[3] = "01 01135404"
can i with linq remove everything before empty space if exist that i will get
[0] = "01010304"
[1] = "01230304"
[2] = "01010784"
[3] = "01135404"
or must i use foreach and then remove data and add it back to array.
Try
_comboBoxItems.Select(s => s.Split(' ').Last()), with a.ToArray()at the end if you require an array.
