如何用多个定界符划分一个字符串,但定界符一直包含在数组中? (VB.NET)
How to divide a string with multiple delimeter, but delimeter is keep include into the array? (VB.NET)
我有一个字符串:
string = "Hello.world, have a nice day"
有没有办法将字符串以点或逗号分割为分隔符,但只将分隔符保留到数组中? (空格是分隔符但不保留)
['Hello','.','world',',','have','a','nice','day']
regex.split(delimeter)
哪个分隔符更好?
这是我的代码
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim arr As String() = Regex.Split(TextBox1.Text, "[.|\,]")
For Each i As String In arr
Console.WriteLine(i)
Next
End Sub

如果您想用点或逗号分隔,您可以将字符 class 更新为 [.,]
,因为字符 class 会匹配任何列出的字符。
字符 class [.|\,]
例如也可以写成 [.,|]
并注意您不必转义逗号。
使用 capture group 来保留分隔符。
你的最终模式看起来像 ([.,])
例如:
Dim s As String = "Hello.world, have a nice day"
Dim arr As String() = Regex.Split(s, "([.,])")
For Each i As String In arr
Console.WriteLine(i)
Next
结果:
Hello
.
world
,
have a nice day
