Question

I have a string containing up to 9 unique numbers from 1 to 9 (myString) e.g. “12345”

I have a list of strings {“1”}, {“4”} (myList) .. and so on.

I would like to know how many instances in the string (myString) are contained within the list (myList), in the above example this would return 2.

so something like

count = myList.Count(myList.Contains(myString));

I could change myString to a list if required.

Thanks very much

Joe

Answer 1

I would try the following:

count = mylist.Count(s => myString.Contains(s));
