public string __Replace(string strValue,string regexOld,string regexNew)
{
RegexOptions options = (RegexOptions.IgnoreCase | RegexOptions.IgnorePatternWhitespace | RegexOptions.Multiline | RegexOptions.Compiled | RegexOptions.ExplicitCapture);
Regex reg = new Regex(regexOld,options);

return reg.Replace(strValue,regexNew);
}

public string retRegex(string str)
{
return __UBBReplace(str,@"(?<enc1>\d{4})(\-)(?<enc2>\d{1,2})(\-)(?<enc3>\d{1,2})([ 0-9:]{6,9})","${enc1}${enc2}${enc3}");
