使用2个字符分割字符串

Question

I'm currently splitting on periods in my code, but found a few issues when I ran it. I was wondering how I could split on ". " instead of just "."

Current Code:

Dim words As String() = item.Split(New Char() {"."c})

Dream Code:

Dim words As String() = item.Split(New Char() {". "c})

It doesn't allow me to add that extra space in after the period, is there a workaround?

Answer 1

To expand on that, see how Replace is used first? First you turn the 2 characters into one that is going to be uniquely identifiable, and then you can split it effectively.

Dim words As String() = item.Replace(". ", "|").Split(New Char() {"|"c})

And you can probably simplify it even more like this:

Dim words As String() = item.Replace(". ", "|").Split("|"c)

That assumes you are using Option Strict On - if not, you can simplify it more like this as the string will be converted to a char automatically:

Dim words As String() = item.Replace(". ", "|").Split("|")

Answer 2

You should use the String.Split Method (String(), StringSplitOptions) overload of String.Split:

Dim s = "1. 2. 3. 4.5.6"
Dim a = s.Split({". "}, StringSplitOptions.None)
Console.Write(String.Join(vbCrLf, a))

outputs:

1
2
3
4.5.6

(Depending on the version of Visual Studio, you might need something like New String() {". "} instead of {". "} .)
