this question has answer here:

i have string of numbers separated commas ,how check if string contained in string .

for example :

if have string :

how check 155 in previous string using linq ?

i assume want check if 1 of items in string given string. split string first delimiter ,, use contains or any:

string[] items = "67,782,452,67632,9,155,323".split(','); bool contains = items.contains("155"); contains = items.any(i => == "155");

the problem contains-check on string "1550" contain "155".
