Implement Find and replace (find given pattern and replace it with a given string)

 

 

 

public static String FindAndReplace(String GivenString, String Pattern, String ReplaceString) { int j = 0; int tempi; for (int i = 0; i < GivenString.Length; i++) { tempi = i; j = 0; while (i<GivenString.Length && j< Pattern.Length && GivenString[i] == Pattern[j])//trying to match the pattern { i++; j++; } if (j == Pattern.Length)//if we find the given pattern { GivenString = GivenString.Substring(0, tempi) + ReplaceString + GivenString.Substring(i, GivenString.Length - i); i = tempi + ReplaceString.Length-1; continue; } //if we didn't find it, set i back i = tempi; } return GivenString; }
