Android Question Regex odd results

[slugger]

Hello,

consider the following code:

Dim s1(),s2 As String
s2="1,,3"
s1=Regex.Split(",",s2)

the s1 array has 3 strings, respectively "1","" and "3", that's ok.

Now consider the following example:

Dim s1(),s2 As String
s2="1,2,"
s1=Regex.Split(",",s2)

This time the s1 array has only 2 elements, respectively "1" and "2", I would have expected a third empty element "" but that does not happen.

Why is regex working like this?

How can I get the s1 array with all the elements even if the last ones are empty strings?

Regex.Split discards trailing empty strings. This is how the native API works. You can check whether the last character is ',' and append another one.
