List<string> data = {"a","b","c","d" ......}

this is my list . i need to add "cc" in every element of that list.

like this , data = {"acc","bcc","ccc","dcc" ......} so on ..

how can i make it dynamically ??

What I have tried:

List<string> data = {"a","b","c","d" ......}
int count = 50 ( i have 50 elements in list )
for (int i = 0; i < count ; i++)

You are going to have to learn to do some of this on your own ... this is trivial code you are asking for help with ...
List<string> data = new List<string>{"a","b","c","d"};

for (int i = 0; i < data.Count; i++)
    data[i] += "cc";

If you want to have a collection that's dynamic, you can return an IEnumerable<string> so it only gets evaluated dynamically - that is, when you use it
List<string> data = new() { "a", "b", "c", "d" };
IEnumerable<string> ccStrings = data.Select(d => d + "cc");
you don't add new elements to the list - you extend the content of an element.
So it looks like :
string s;

for (var i = 1; i <= 50; i++)
    s = data[i];
    data[i] = s + "cc";

Um ... Ralf ... I know it's early in the morning, but ... that won't compile! :laugh:

Hi Griff,
the Brackets ? Right ?
But you are right - today it's really very early in the morning ... ;)

Don't forget the range of the index. :)
