[英]Minifier that preserves conditional comments?

There's also a .NET port of YUI Compressor which allows you to:- 还有一个YUI Compressor的.NET端口,您可以:-
because this is a port of the (original) java version YUI Compressor, which Vinnie and Crescentfresh mention above, it should give you the same results BUT all in the .NET environment -- no need for java. 因为这是(原始)Java版本YUI Compressor的端口,上面的Vinnie和Crescentfresh提到了它,所以它应该在.NET环境中为您提供相同的结果-不需要Java。
