上回我们说到Expression Tree是一种表示编程语言中“表达式”概念的树状数据结构,并且学习了从Lambda表达式自动生成表达式树的C#语法。那么它到底有什么用呢?其实上一回已经提到了Expression Tree的基本功能:分析表达式的逻辑、保存和传输表达式以及重新编译表达式。现在我们就分别来看这三项基本功能如何使用。 分析表达式的逻...

因此上述代码中的Where和Select分别接受了一个Expression Tree作为参数。最后的query对象中包含了整个序列每个操作对应的表达式树,QueryProvider就可以通过分析表达式树,翻译成SQL或者直接进行查询动作了。 这种用法有点类似于解释器模式。你可以用Expression Tree来表示一种逻辑,然后解析它来驱动你的业务逻辑。原本属于具体语言...

The growing RNA chain remains linked to the polymerase as transcription proceeds, forming the characteristic “Christmas tree” pattern observed in the electron microscope. Transcription terminates by the release of the primary RNA transcript, which undergoes RNA-processing reactions. Thus the transcription...
