Question

在vb.net中如何从字符串中删除字符串中的两个已知字符之间的字符。例如，如何从标签之间的数字中删除逗号

余额，＃163,464.24＃，Cashbook结算余额：，＃86,689.45＃，Money，End

Answer 1

您可以使用循环和StringBuilder：

来使用这种简单有效的方法

Dim text = "Balance,#163,464.24#,Cashbook Closing Balance:,#86,689.45#,Money,End"
Dim textBuilder As New StringBuilder()
Dim inHashTag As Boolean = False

For Each c As Char In text
    If c = "#"c Then inHashTag = Not inHashTag ' reverse Boolean
    If Not inHashTag OrElse c <> ","c Then
        textBuilder.Append(c) ' append if we aren't in hashtags or the char is not a comma
    End If
Next
text = textBuilder.ToString()

Answer 2

因为我对正则表达式不好：

Dim str = "Balance,#163,464.24#,Cashbook Closing Balance:,#86,689.45#,Money,End"
Dim split = str.Split("#"c)
If UBound(split) > 1 Then
    For i = 1 To UBound(split) Step 2
        split(i) = split(i).Replace(",", "")
    Next
End If
str = String.Join("#", split)
