C# 7 finally introduced a long-awaited feature called “pattern matching”. If you’re familiar with functional languages like F# you may be slightly disappointed with this feature in its current state, but even today it can simplify your code in a variety of different scenarios. Every new fea...

You can test if a given observation has a non-null annotation using the following pattern matching expression: C# if(observation.Annotationis{ }) { Console.WriteLine($"Observation description:{observation.Annotation}"); } List patterns You can check elements in a list or an array using alist ...
The following C# expressions and statements support pattern matching:is expression switch statement switch expressionIn those constructs, you can match an input expression against any of the following patterns:Declaration pattern: check the run-time type of an expression and, if a match succeeds, ...
Chapter 4. Pattern Matching Scala’s pattern matching provides deep inspection and decomposition of objects in a variety of ways. It’s one of my favorite features in Scala. For your own … - Selection from Programming Scala, 3rd Edition [Book]
Pattern variables differ from other local variables in that they can only be assigned a value by pattern matching (14.30.3). This process is conditional; a pattern variable is only assigned a value if the pattern match succeeds. Accordingly the scope of pattern variables is carefully defined so...
java8虽然加入了一些函数式的特性,但是紧紧只是迈出了一小步,Classic FP 即:ADT(algebraic data type) + interpreter 的方式并不被直接支持,ADT可以通过像Scala(case class)那样用面向对象的方式去模拟,interpreter 虽然可以通过一些方式(比如Visiter模式)去模拟,但是没有Pattern Matching 那么直观 除此之外 Pattern Matc...
Method and system for multi-character multi-pattern pattern matching Disclosed is a method and system for multi-character multi-pattern pattern matching. In the multi-character multi-pattern pattern matching method, patterns in an input stream are detected by transitioning between states of a "compres...
The current explosion of stored information necessitates a new model of pattern matching, that of compressed matching. In this model one tries to find all occurrences of a pattern in a compressed text in time proportional to the compressed text size, i.e., without decompressing the text. The...
You can learn more about the process for adopting feature speclets into the C# language standard in the article on thespecifications. We are considering a small handful of enhancements to pattern-matching for C# 9.0 that have natural synergy and work well to address a number of common programmin...
