Here's one way to generalize it: using System; using System.Text.RegularExpressions; class Test { static void Main() { string original = "(My friend name is \"WALTERS K,SCHULTHIES SPL \",\"Lenny\",salunke)"; int n = 2; // get index of 'n'th comma and replace it with a space string result = original; int count = 0; int i; for(i = 0; i { if (original[i] == ',') count++; if (count == n) break; } if (count == n ) { result = original.Substring(0, i) + " " + original.Substring(i + 1); } Console.WriteLine(result); Console.ReadKey(); } } You can also use a regular expression : using System; using System.Text.RegularExpressions; class Test { static void Main() { string original = "(My friend name is \"WALTERS K,SCHULTHIES SPL \",\"Lenny\",salunke)"; Regex r = new Regex(","); MatchCollection mc = r.Matches(original); int n = 2; // get index of 'n'th comma and replace it with a space string result = original; if (mc.Count >= n) { int index = mc[n-1].Index; result = r.Replace(original, " ", 1, index); } Console.WriteLine(result); Console.ReadKey(); } }
