正则表达式匹配＆＃34; ***任何***客户编号9999999 ***任何***＆＃34;

Question

我想在VB.net中使用Regex.Ismatch函数来匹配模式***anything***Customer No. 9999999 ***anything***

即＆＃34;客户编号＆＃34; - ＆GT;静态的 在＆＃34;客户编号＆＃34; 7个数字字符 - ＆gt;动态

到目前为止，我正在试用^ .*Customer No\. [0-9]+ .*$。我很接近，但如果只有Customer No. 9999999只有前缀和后缀

，它才会接受

Answer 1

c＃：

 string s = " Customer No. 9999999";
                Regex regex = new Regex(@"^Customer No. +[0-9]{7}$");
                Match match = regex.Match(s);
                if (match.Success)
                {
                    Console.WriteLine(match.Value);
                }
                else
                {
                    Console.WriteLine("not match");
                }

VB：

Dim s As String = "Customer No. 9999999"
Dim regex As New Regex(@"^Customer No. +[0-9]{7}$")
Dim match As Match = regex.Match(s)
If match.Success Then
    Console.WriteLine(match.Value)
Else
    Console.WriteLine("not match")
End If

Answer 2

尝试使用此模式：

"Customer No\. \d{7}"

这是捕获文字＆＃34;客户编号＆＃34;加上你可以访问的7个连续数字，如：

Imports System.Text.RegularExpressions

Module Module1
    Sub Main()
        Dim data As String = "***anything***Customer No. 9999999 ***anything***"
        Dim matcher As Match = Regex.Match(data, "Customer No\. \d{7}")
        If matcher.Success Then
            Console.WriteLine(matcher.Value)
        End If
    End Sub
End Module

结果：

Customer No. 9999999
