正則表達式可以匹配「*** ***任何客戶號9999999 *** ***東西」

Question

我想用Regex.Ismatch功能在VB.net到***anything***Customer No. 9999999 ***anything***

即「客戶號」匹配模式 - >靜態 後「客戶號碼」7數字字符 - >動態

我的正則表達式迄今嘗試^ .*Customer No\. [0-9]+ .*$。我很接近，但如果只有Customer No. 9999999如果有前綴和後綴，只匹配它不接受

Answer 1

給這個模式的嘗試：

"Customer No\. \d{7}" 

這是捕獲字面「客戶編號」加上連續7個位數成whic ...你可以訪問，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 

結果：

Customer No. 9999999 

Answer 2

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
