Question

I need a method that returns every other character in a string starting with the first character. For example, a method call with (“Java-language”) returns “Jv-agae.”

     private static void NewMethod(string word)
     {
         // here comes the code
     }

Answer 1

var str = "Java-language";
var xx = new string(str.Where((ch, index) => index % 2 == 0).ToArray());
Console.WriteLine(xx);

Or this one:

var xx = string.Join<char>("", str.Where((ch, index) => (index & 1) == 0));
