C＃如何拆分包含数组中数字的字符串

Question

我有一个这样的字符串：

string test = "1Hello World  2I'm a newbie 33The sun is big 176The cat is black";

我想拆分字符串并放入如下数组：

1 Hello World
2 I'm a newbie 
33 The sun is big 
176 The cat is black

结果可能在String []，ArrayList，List或Linq

中

添加了我尝试但不起作用的内容..

 ArrayList oArrayList = new ArrayList();
 Regex oRegex = new Regex(@"\d+");
 Match oMatch = oRegex.Match(test);
 int last = 0;

 while (oRegex.Match(test).Success)
 {
     oArrayList.Add(oMatch.Value + " " + test.Substring(last, oMatch.Index));
     last = oMatch.Index;
     test = test.Remove(0, oMatch.Index);
     oMatch = oRegex.Match(test);
 }

Answer 1

试试这个：

string test = "1Hello World  2I'm a newbie 33The sun is big 176The cat is black";

Regex regexObj = new Regex(@"(\d+)([^0-9]+)", RegexOptions.IgnoreCase);
Match match = regexObj.Match(test);
while (match.Success) 
{
  string numPart = match.Group[1].Value;
  string strPart = match.Group[2].Value;
  match = match.NextMatch();
}

输出：

Answer 2

说实话很简单

 string test = "1Hello World  2I'm a newbie 33The sun is big 176The cat is black";
 var tmp = Regex.Split(test,@"\s(?=\d)");

tmp将是一个字符串数组

给定输入字符串test，您可以使用Regex.Split拆分小数点边界上的字符串。在每个元素的数字和文本之间添加空格需要在每个元素上调用Regex.Match以获得所需的格式：

var r = Regex.Split(test, @"(?<=\D)(?=\d)") // split at each boundary 
                                            // between a non-digit (\D)
                                            // and digit (\d).
            .Select(a=>Regex.Match(a, @"(\d+)(.*)").Result("$1 $2"));
                                           // ^ insert a space between
                                           // decimal and following text

结果是IEnumerable<string>，可以在Linq中根据需要进行处理。
