您好我正在使用Regex Hero制作正则表达式。它在Regex Hero中按预期工作。然后我将其转移到vb.net，现在我从相同的确切数据得到不同的结果。我不明白！
正则表达式：
\d{10,13}.+?(?=(\bF\b|\bT\b|\bCT\b))
.net代码：
Dim strRegex As String = "\d{10,13}.+?(?=(\bF\b|\bT\b|\bCT\b))"
Dim myRegex As New Regex(strRegex, RegexOptions.None)
Dim strTargetString As String = a
For Each myMatch As Match In myRegex.Matches(strTargetString)
If myMatch.Success Then
RichTextBox1.AppendText(myMatch.Value & Environment.NewLine)
End If
Next
