Question

I’m making an app and I’m almost done. I just need to know how I can streamread a txt list and foreach line, add numbers 0-x (x will be the number the user puts in the textbox) and add it to a list. So basically, it would be like this

You import a list with ‘dog’ on one line, ‘cat’ on another, and ‘fish’ on the third. You type ‘5’ into the textbox. the app puts all this into a list:

dog1
dog2
dog3
dog4
dog5
cat1
cat2
cat3
cat4
cat5
fish1
fish2
fish3
fish4
fish5

thanks!

Answer 1

The code below should work for you. I assume you can acquire the count value on your own.

var animals = File.ReadAllLines("yourFile.txt"); //new[] {"dog", "cat", "fish"};
var count = 5;

var merged =
    from a in animals
    from n in Enumerable.Range(1, count)
    select a + n;

foreach (var m in merged)
    Console.WriteLine(m);  //act on each however you want
