C# CSS Stylesheet Compression, fast website loading

Hi All, Here's a static class developed in c# to compress Css stylesheets,
It removes all “\r\n” (newline carriage return) , all “\t” (tab) all spaces before and after “:” “;” , it also remove all comment from your css.
Thanks to this function Stylesheet should be more light and fast for web and you can remove additionals spaces manually for complete optimization .
You can copy your css and pass it to class with:
textBox2.Text = LWEBCODE.Get_CSS_RTM(textBox1.Text);
I suggest to make a form o webform with 2 textboxes and paste in textbox1 your css stylesheet ,result can be show in textbox2 , after paste into css_runtime_sheet.css, 
REMEMBER on pagae_load event or in <head> tag to correctly set the right stylesheet: version for development and debug, or runtime version
Please for any optimization or suggestion contact us.
Here the code:


using System;
using System.Collections.Generic;
using System.Text;
using System.Text.RegularExpressions;
