將變量粘貼到正則表達式中

Question

幫助將變量zone粘貼到正則表達式模式中。在我看來，我嘗試了所有可能的變體......總是出現錯誤！ （此處不是靜態字符串UntrustGn）

  List<string> zones = new List<string> 
      { "UntrustGi", 
       "DMZPub", 
       "DMZMMS", 
       "DmzGi", 
       "TrustGi", 
       "TrustGn", 
       "DmzGn", 
       "UntrustGn", 
       "DMZLOM" }; 


      foreach (string zone in zones) 
      { 
       string patternZone = @"set address ""(UntrustGn)"" ("".*"") ([0-9]+.[0-9]+.[0-9]+.[0-9]+)([0-9]+.[0-9]+.[0-9]+.[0-9]+)"; 

Answer 1

使用string.Format，像這樣：

foreach (string zone in zones) { 
    string patternZone = string.Format(@"set address ""{0}"" ("".*"") ([0-9]+.[0-9]+.[0-9]+.[0-9]+)([0-9]+.[0-9]+.[0-9]+.[0-9]+)", zone); 
    ... 
} 

Answer 2

這樣做：

foreach(string zone in zones) 
{ 
    string ptternZone = string.Format(@"set address ""{0}"" ("".*"") ([0-9]+.[0-9]+.[0-9]+.[0-9]+)([0-9]+.[0-9]+.[0-9]+.[0-9]+)", zone); 
} 

上述用途string.Format方法。
