C# Array Map/Collect

Question

In Ruby you can use the map/collect method on an array to modify it:

a = [ "a", "b", "c", "d" ]
a.collect! {|x| x + "!" }
a                            #=>  [ "a!", "b!", "c!", "d!" ]

Is there a simple way to do this in C#?

Answer 1

a = a.Select( s => s + "!" ).ToArray();

Answer 2

you may try this

var a = new[] { "a", "b", "c", "d" };

a = a.Select(p => p + "!").ToArray();

Answer 3

Yup, using Linq (but this won't modify the original collection)

var a=new[]{"a","b","c","d"};
a.Select(x=>x+"!");

Answer 4

I prefer using ConvertAll since it's quicker and I believe more intuitive.

var a = a.ConvertAll(x => x + "!").ToArray();
