喜欢做像

    }

感谢您的帮助......！

Answer 1

有RegEx.Matches方法：

foreach (Match match in regex.Matches(myStringToMatch))
{
  MessageBox.Show(match.Value);
}

要获取匹配的子字符串，请使用Match.Value属性，如上所示。

Answer 2

来自MSDN

  string pattern = @"\b\w+es\b";    
  Regex rgx = new Regex(pattern);    
  string sentence = "Who writes these notes?";

  foreach (Match match in rgx.Matches(sentence))
  {

     Console.WriteLine("Found '{0}' at position {1}", 
                       match.Value, match.Index);
  }

Answer 3

首先需要声明要分析的字符串，然后声明正则表达式模式。最后在循环中你必须实例regex.Matches(stringvar)

string stringvar = "dgdfgdfgdf7hfdhfgh9fghf";
Regex regex = new Regex(@"\d+");

foreach (Match match in regex.Matches(stringvar))
{
    MessageBox.Show(match.Value.ToString());
}

在字符串中查找每个RegEx匹配项
