Tips and Notes
注意 Note: If an empty string (“”) is used as the separator, the string is split between each character.
注意:如果用空字符(“”)作为分隔符号,字符串将被分解成每个所包含的字符所组成的数组。
Example
实例 In this example we will split up a string in different ways:
在本例中,我们将用两种不同的方法分解一个字符串:

The output of the code above will be:

输出结果为:
How,are,you,doing,today?
H,o,w, ,a,r,e, ,y,o,u, ,d,o,i,n,g, ,t,o,d,a,y,?
How,are,you

和C#中的将字符串以某字符分开含义一样!:5_113:
