Concatenate a constant string to each item in a List<string> using LINQ

Question

I am using C# and .Net 4.0.

I have a List<string> with some values, say x1, x2, x3. To each of the value in the List<string>, I need to concatenate a constant value, say "y" and get back the List<string> as x1y, x2y and x3y.

Is there a Linq way to do this?

Answer 1

List<string> yourList = new List<string>() { "X1", "Y1", "X2", "Y2" };
yourList = yourList.Select(r => string.Concat(r, 'y')).ToList();

Answer 2

list = list.Select(s => s + "y").ToList();
