Custom String Methods using C#

This one's only slightly faster public static int CharCount2(String strSource, String strToCount) { int iCount = 0; int iPos = strSource.IndexOf(strToCount); while (iPos != -1) { iCount++; iPos = strSource.IndexOf(strToCount, iPos+1); } return iCount; }

public static String Reverse2(String strParam) { byte[] rev = Encoding.ASCII.GetBytes(strParam); Array.Reverse(rev); return Encoding.ASCII.GetString(rev); }

Sorry if this is a repeat... I'm not sure if the first comment made it.... Besides being simpler & easier to understand, this is sgnificantly faster: public static String PCase2(String strParam) { StringBuilder sb = new StringBuilder(strParam.Length); char cPrev = '.'; // start with something to force the next character to upper. foreach(char c in strParam) { if (cPrev == '.' || Char.IsWhiteSpace(cPrev)) sb.Append(Char.ToUpper(c)); else sb.Append(Char.ToLower(c)); cPrev = c; } return sb.ToString(); }
