c# - Check if Listbox contains a certain element -


i know question posted here multiple times i've read threads , nothing works me decided ask here.

i want check if string in listbox. i've tried 

   listbox.items.contains("stringtomatch")

but nothing.

i tried

 foreach (var item in form1.filtertypelist.items)                 {                     if (item.tostring() == "stringtomatch")                     {                         break;                                   }

he doesn't find anything. why? how can solve that?

try using way... findbytext

strig tomatch = "stringtomatch"; listitem item = listbox1.items.findbytext(tomatch); if (item != null) {     //found } else {     //not found }
