识别产品名称中是否存在符号

Question

我有这个需要识别具有模式符号的产品列表。到目前为止，下面是我用来识别它们的代码。不幸的是，当我调试程序时，它不识别模式。

  string[] patterns = new string[] { "." ,",", ";", "'", "`", ":", "/", "\\", "*", "|" ,"(", ")","[", "]", "{", "}", "<", ">" }; 

      List<Product> products = new List<Product> 
      { 
       new Product { ID = 1, Name = "Jenny's Product", Price = 10 }, 
       new Product { ID = 2, Name = "Brunus C.O.", Price = 10 }, 
       new Product { ID = 3, Name = "GreenCross", Price = 10 }, 

      }; 
      foreach (var item in products) 
      { 
       if (patterns.Contains(item.Name)) 
       { 
        Console.WriteLine(item.Name); 
       } 
      } 

      Console.ReadLine(); 

Answer 1

patterns.Contains(item.Name) 

它为什么会认识到模式，如果项目名称包含在该模式你是问。不是。您想询问产品名称中是否包含任何图案：

patterns.Any(item.Name.Contains)
