c# - How to search through two list members? -

i have next class:

public class fixfirstduplicate { public string firstparam { get; set; } public string secondparam { get; set; } }

and list:

public static list<fixfirstduplicate> firstduplicate = new list<fixfirstduplicate>();

the list total of values firstparam , secondparam each correspond each other. it's table, first firstparam associated first secondparam , on.

then have:

list<string> conlines = new list<string>();

i want through conlines, , everytime string contains both firstparam , secondparam, perform method on string.

if doing 1 list, firstparam, utilize hashset, don't know how equivalent given have firstparam , secondparam

you need check if conlines contains both firstparam or secondparam like:

var query = firstduplicate.where(r => conlines.contains(r.firstparam) && conlines.contains(r.secondparam));

edit: if want phone call method when find match , order of import can utilize simple foreach loop like:

foreach (var item in firstduplicate) { string matchingstring = conlines.firstordefault(r => (r.indexof(item.firstparam)>= 0 && r.indexof(item.secondparam) >= 0) && (r.indexof(item.firstparam) < r.indexof(item.secondparam))); if(matchingstring != null) { //callyourmethod(matchingstring); } }
