I have a List<string>
that receives the phone number of all the contacts in the phone, until then without problem, but I want to perform operations with the elements of this list, but I have some problems.
An example of a possible result:
lst = {"*126", "+55 3412345678", "12345678", "87654321", "3498761232"};
If you look, they are all phone numbers, and I stored it as a string, to make it easier. Now I have to perform a search in this list, in all elements of it (I do not know how much elements the list will have, because it depends on the user's schedule).
Example:
User type 123 in the textbox num
and when clicking the button I make the search in my list, the result should be:
+55 3412345678
12345678
3498761232
Well, if we look at it, they are the only elements in the list that contain the string entered ( 123
).
So briefly, how to search a list of indeterminate length, a string that can be anywhere in the element (start, middle, end, etc.), the search should return a maximum of 3 values, ie if we have another element such as 51234251
, although it contains 123
it would not be returned, since we already found 3 elements with 123
before it.
Sorry if it was confusing, it was the most detailed way I could report, in short, is to look for a partial string in a list and return the first three elements that contain that string. But I was not able to do such a task, I hope someone can help me, because it was already a labor and time to figure out how to get the number of the contacts and store it on the list.
