Title: The pattern is not exactly matching in c#

The matches given in the sample are exactly what i needed. But the pattern is not matching in c#. The character '\' denotes an Error "Unrecognized escape sequence" and only first 5 digits are only recognized not - decimal & - digits after decimal point Thank you..

Is there a way to limit the number before the decimal to a range. For e.g a.bcd where a should be within 1-4 and bcd should be [0-9] but only limited to 3 digits
