ASP. NET MVC page code compression filter

The following filters are defined first for code compression.

/*page Compression Filters*/     Public classWhitespacefilter:stream {PrivateStream _shrink; Privatefunc<string,string>_filter;  PublicWhitespacefilter (Stream shrink, func<string,string>filter) {_shrink=shrink; _filter=filter; }         Public Override BOOLCanRead {Get{return true; } }         Public Override BOOLCanSeek {Get{return true; } }         Public Override BOOLCanWrite {Get{return true; } }         Public Override voidFlush () {_shrink. Flush (); }         Public Override LongLength {Get{return 0; } }         Public Override LongPosition {Get;Set; }  Public Override intRead (byte[] Buffer,intOffsetintcount) {            return_shrink.        Read (buffer, offset, count); }         Public Override LongSeek (Longoffset, SeekOrigin origin) {            return_shrink.        Seek (offset, origin); }         Public Override voidSetLength (Longvalue) {_shrink.        SetLength (value); }         Public Override voidClose () {_shrink.        Close (); }         Public Override voidWrite (byte[] Buffer,intOffsetintcount) {            //capture the data and convert to string            byte[] data =New byte[Count]; Buffer.blockcopy (buffer, offset, data,0, Count); strings = encoding.getencoding ("gb2312").            GetString (buffer); //Filter the strings =_filter (s); //write the data to stream            byte[] Outdata = encoding.getencoding ("gb2312").            GetBytes (s); _shrink. Write (Outdata,0, Outdata. GetLength (0)); }    }     Public classWhitespacefilterattribute:actionfilterattribute { Public Override voidonactionexecuting (ActionExecutingContext filtercontext) {varRequest =filterContext.HttpContext.Request; varResponse =FilterContext.HttpContext.Response; Response. Filter=NewWhitespacefilter (response. Filter, S = ={s= Regex.Replace (S,@"\s+ (?=<) |\s+$| (?<=>) \s+|<!--. +-->| []+//.+\n|/\*.+\*/|\n",""); //Single-line doctype must be preserved                varFirstendbracketposition = S.indexof (">"); if(Firstendbracketposition >=0) {s= S.remove (Firstendbracketposition,1); S= S.insert (Firstendbracketposition,">"); }                returns;        }); }    }    /*page Compression filter End*/

Used on the action to compress the page.

[Whitespacefilter]  Public ActionResult Home () {      return  View ();}

We can modify the substitution rules on our own to achieve optimization.

@" \s+ (?=<) |\s+$| (?<=>) \s+|<!--. +-->| []+//.+\n|/\*.+\*/|\n""];
