Set the strings −

List<string> val = new List<string>();

// list of strings
val.Add("water");
val.Add("food");
val.Add("air");

Use Join method to convert several strings into a single comma-delimited string −

string.Join(",", val.ToArray());

Here is the complete code −

using System;
using System.Collections.Generic;
public class Demo {
   public static void Main() {

      // list of strings
      val.Add("water");
      val.Add("food");
