Appending characters to a List string

append, c#, list

Solution

It's not really clear why you're using a `StringBuilder` at all here, or why you'd be trying to do a join. It sounds like you want:

var suckingList = myList.Select(x => "my " + x + " sucks")
                        .ToList();

This is the absolutely normal way of performing a projection to each item in a list using LINQ.

Problem

I have an optional custom prefix and suffix in my application, that I want to add to each of the items in my string List. I have tried all of the following and none are working. Can someone point me in the right direction please? ``` List<string> myList = new List<string>{ "dog", "cat", "pig", "bird" }; string prefix = "my "; string suffix = " sucks!"; StringBuilder sb = new StringBuilder(); sb.Append(suffix); sb.Insert(0, prefix); MyList = sb.ToString(); //This gives me red squigglies under sb.ToString(); ``` I also tried: ``` myList = myList.Join(x => prefix + x + suffix).ToList(); //Red squigglies ``` and: ``` sortBox1.Join(prefix + sortBox1 + suffix).ToList(); //Red squigglies ``` Where am I going wrong here?
