加入了智能分离器 [英] Join with intelligent separators

问题描述

这是很容易，当然写的，但在C＃2010，有一个内置的加入（或类似）方法，只会增加一个分隔符，如果previous和下一个元素都是非空和非空？

It's easy enough to write, of course, but in C# 2010, is there a built-in Join (or similar) method that will only add a separator if both the previous and next elements are non-null and non-empty?

在换句话说 SmartJoin（，，胡德号，罗宾）将产生胡德，罗宾，但 SmartJoin（ ，罗宾汉，的String.Empty）会产生简单的劫富济贫。

In other words SmartJoin(", ","Hood","Robin") would produce "Hood, Robin" but SmartJoin(", ", "Robin Hood", string.Empty) would produce simply "Robin Hood".

推荐答案

有没有内置的加入，你所需要的。

There is no built-in join which you need.
