Dim ns As new List(of String)

ns.AddRange(new String() {"成人","儿童","单房差"})

Dim str As String = "成人2870,儿童2270,单房差770"

Dim arr() As String = str.Split(",")

Dim n As String

Dim p As Double

str = ""

For Each Ar As String In arr

For Each n1 As String In ns

If ar.Contains(n1) Then

n = n1

Exit For

End If

p = val(ar.Replace(n,"")) - 10

str &= n & p & ","

Output.Show(str)

具体什么应用到项目里留做作业
