Yui.Compressor高性能ASP.NET开发：自动压缩CSS、JS

//文件内容

string strContent = File.ReadAllText(jsPath, Encoding.UTF8);

 

//初始化

var js = new JavaScriptCompressor(strContent, false, Encoding.UTF8, System.Globalization.CultureInfo.CurrentCulture);

 

//压缩该js

strContent = js.Compress();

File.WriteAllText(jsPath, strContent, Encoding.UTF8);

string strContent = File.ReadAllText(cssPath, Encoding.UTF8)



//进行压缩

strContent = CssCompressor.Compress

(strContent);



File.WriteAllText(cssPath, strContent, Encoding.UTF8);

ItemGroup\CssFiles or ItemGroup\JavaScriptFiles: add zero to many files you wish to include in this compression task.

                                                             Don‘t forget, you can use the wildcard (eg. *.css, *.js) if you feel up to it.

                                                             Finally, at least one item is required - either a css file or a js file.

 

CssFiles/JavaScriptFiles data format: Please do not touch this.

DeleteCssFiles: [Optional] True | Yes | Yeah | Yep | True | FoSho | FoSho. Default is False. Anything else is False. (eg. blah = false, xxxx111 = false, etc)

CssCompressionType: YuiStockCompression | MichaelAshsRegexEnhancements | HaveMyCakeAndEatIt or BestOfBothWorlds or Hybrid; Default is YuiStockCompression.

ObfuscateJavaScript: [Optional] refer to DeleteCssFiles, above.

PreserveAllSemicolons: [Optional] refer to DeleteCssFiles, above.

DisableOptimizations: [Optional] refer to DeleteCssFiles, above.

EncodingType: [Optional] ASCII, BigEndianUnicode, Unicode, UTF32, UTF7, UTF8, Default. Default is ‘Default‘.

DeleteJavaScriptFiles: [Optional] refer to DeleteCssFiles, above.

LineBreakPosition: [Optional] the position where a line feed is appened when the next semicolon is reached. Default is -1 (never add a line break).
(zero) means add a line break after every semicolon. (This might help with debugging troublesome files).         

LoggingType: None | ALittleBit | HardcoreBringItOn;  Hardcore also lists javascript verbose warnings, if there are any (and there usually is :P ).

ThreadCulture: [Optional] the culture you want the thread to run under. Default is ‘en-gb‘.

IsEvalIgnored: [Optional] compress any functions that contain ‘eval‘. Default is False, which means a function that contains

                           ‘eval‘ will NOT be compressed. It‘s deemed risky to compress a function containing ‘eval‘. That said,

if the usages are deemed safe this check can be disabled by setting this value to True.
