Last item in the c# list

I am need to highlight the keywords or tags in an article & pass variable to jQuery Array i am using property to pass value from C# to java-script which works i also need to format my keywords which in database are stored like one, two, three, four, five,six,seven

in order to make it work i have to wrap each keyword in single ' or double quotes".

JQuery

    function HighlightKeywords(keywords) {
        var el = $("body");
        $(keywords).each(function () {
            var pattern = new RegExp("(" + this + ")", ["gi"]);
            var rs = "<a href='search.aspx?search=$1'<span style='background-color:#FFFF00;font-weight: bold;background-color:#FFFF00;'>$1</span></a>";
            el.html(el.html().replace(pattern, rs));
        });
    }

HighlightKeywords(["<%= MyProperty %>]");

C# Code

string _sFinalList = null;

protected string MyProperty { get { return _sFinalList; } }
string sKewords = "one, two, three, four, five,six,seven";

List<string> lstKewords = sKewords.Split(',').ToList();
foreach (string list in lstKewords) // Loop through List with foreach
{
   _sFinalList += "'" + list + "',";

}

Problem with this code is that it ads , after the last words i want to know what is the best way to avoid adding , after the last words

Current OUTPUT: "'one', 'two', 'three', 'four', 'five','six','seven',"

Desired OUTPUT: "'one', 'two', 'three', 'four', 'five','six','seven'"

Help in this regard is appreciated

In C#, use String.Join() :

List<string> lstKeywords = sKeywords.Split(',').ToList();

var quotedKeywords = lstKeywords.Select(s => "'" + s + "'");

string _sFinalList = string.Join(",", quotedKeywords);

you may simply remove lastIndexOf(",") with substring function of string class after you complete the for loop.

OR

you may add and if statement in your for loop that would add "," if loop is not in its last iteration.

You could use String.Join

var result = string.Format("'{0}'", string.Join("','", yourList));

You can using String.Join()

string sKewords = "one, two, three, four, five,six,seven";
List<string> lstKewords = sKewords.Split(',').ToList();
var _partial = lstKewords.Select(x => "'" + x + "'");
Var _result = String.Join(",", _partial);
