在字符串中查找每个RegEx匹配项

Question

我喜欢做类似的事情

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

谢谢你的帮助...!

Answer 1

有一种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,请使用该Match.Value属性,如上所示.

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);
  }

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());
}
