vb.net - 获取其他字符串之间的字符串 vb.net

Question

我有下面的代码。如何获取括号内的字符串？谢谢。

Dim tmpStr() As String
    Dim strSplit() As String
    Dim strReal As String
    Dim i As Integer

    strWord = "hello (string1) there how (string2) are you?"

    strSplit = Split(strWord, "(")
    strReal = strSplit(LBound(strSplit))

    For i = 1 To UBound(strSplit)
        tmpStr = Split(strSplit(i), ")")
        strReal = strReal & tmpStr(UBound(tmpStr))
    Next

Answer 1

Dim src As String = "hello (string1) there how (string2) are you?"
Dim strs As New List(Of String)

Dim start As Integer = 0
Dim [end] As Integer = 0

While start < src.Length

    start = src.IndexOf("("c, start)
    If start <> -1 Then
        [end] = src.IndexOf(")"c, start)
        If [end] <> -1 Then
            Dim subStr As String = src.Substring(start + 1, [end] - start - 1)
            If Not subStr.StartsWith("(") Then strs.Add(src.Substring(start + 1, [end] - start - 1))
        End If
    Else
        Exit While
    End If

    start += 1 ' Increment start to skip to next (

End While

这应该可以。

Dim result = Regex.Matches(src, "\(([^()]*)\)").Cast(Of Match)().Select(Function(x) x.Groups(1))

也可以。
