.net - 如何在 VB.Net 中拆分复杂的字符串

Question

我有一个来自 Javascript 函数调用的参数字符串

ITQPopup('100',255,'2932 NTYwNDUwMTA0MDYzMDM);3094 V0FZ','-1909432577',0,0)

如您所见，这是非常糟糕的编码，传递了 6 个参数

'100'
255
'2932 NTYwNDUwMTA0MDYzMDM);3094 V0FZ'
'-1909432577'
0 
0

我会用“,”(逗号)分隔字符串，但恐怕第三个参数中可能有逗号。如何拆分这个字符串？

您可以使用 RegEx 轻松完成此操作。例如:

Dim input As String = "ITQPopup('100',255,'2932 NTYwNDUwMTA0MDYzMDM);3094 V0FZ','-1909432577',0,0)"
Dim pattern As String = "ITQPopup\('(.*?)',(.*?),'(.*?)','(.*?)',(.*?),(.*?)\)"
Dim m As Match = Regex.Match(input, pattern)
If m.Success Then
    Dim param1 As String = m.Groups(1).Value
    Dim param2 As String = m.Groups(2).Value
    Dim param3 As String = m.Groups(3).Value
    Dim param4 As String = m.Groups(4).Value
    Dim param5 As String = m.Groups(5).Value
    Dim param6 As String = m.Groups(6).Value
End If

如有必要，您可以进一步改进模式，以允许参数之间有空格等。但这是最简单的工作示例。
