创建数组函数可以将两个数组连接或结合成一个，或向数组中增加元素，这取决于你自己的设定。

Depending on how you configure it, Build array concatenates, or combines, two arrays into one, or adds extra elements to an array.

连接两个序列的另一方法是构造序列的一个集合(例如一个数组)，然后应用SelectMany方法，将其传递给标识选择器函数。

An alternative way of concatenating two sequences is to construct a collection, for example an array, of sequences and then apply the SelectMany method, passing it the identity selector function.
