c#从字符串中提取多个数字

Question

我正在尝试从具有大量格式的字符串中提取不同长度的整数。有问题的字符串可能如下所示:

string s = "Hallo (221122321 434334 more text3434 even mor,34343 343421.343sf 343";

我正在寻找的输出是一个数组:

{221122321,434334,3434,34343,343421,343,343}

Answer 1

var result = new Regex(@"\d+").Matches(s)
                              .Cast<Match>()
                              .Select(m => Int32.Parse(m.Value))
                              .ToArray();
