c# change the string in a foreach string loop

Question

I\'m trying to cycle through strings in a list with a foreach loop, but I don\'t know how to change the item that\'s being referenced - How can I change s in the li

Answer 1

You can do this with Linq quite easily:

var newStringList = myStringList
    .Select(s => s + "-")
    .ToList();

If you really want to modify the existing list, you can use a classic for loop, for example:

for (var i = 0; i < myStringList.Count; i++)
{
    myStringList[i] = myStringList[i] + "-";
}
