Question

每当我找到第一个非alpha或空格时，我都试图分割出一个字符串（在索引处）。

我的正则表达式真的很生疏，并试图找到一些方向让这个工作。

示例：＆＃34; 2015年8月14日收到的付款$ 0.00＆＃34;是字符串。我能找到第一个数字

问题出在一个字符串，如＆＃34; Amount This Period + $ 57.00＆＃34; 我结束了＆＃34;金额这个时期+ $＆＃34;

如何在C＃中使用Regex，如果我还想包含特定的非字母数字字符来检查string alphabet = String.Empty; string digit = String.Empty; int digitStartIndex; Match regexMatch = Regex.Match("Payments Received by 08/14/2015 $0.00", "\\d"); digitStartIndex = regexMatch.Index; alphabet = line.Substring(0, digitStartIndex); digit = line.Substring(digitStartIndex);？

修改：我正在寻找上面例子中的输出（变量字母和数字）我正在努力做到。
＆＃34;此期间金额＆＃34;
＆＃34; + $ 57.00＆＃34;

Answer 1

啊，那么你想要这个我想：

void Main()
{
    var regex = new Regex(@"(.*?)([\$\+\-].*)");
    var a = "Payments Received by 08/14/2015 $0.00";
    var b = "Amount This Period + $57.00";

    Console.WriteLine(regex.Match(a).Groups[1].Value);
    Console.WriteLine(regex.Match(a).Groups[2].Value);
    Console.WriteLine(regex.Match(b).Groups[1].Value);
    Console.WriteLine(regex.Match(b).Groups[2].Value);
}

输出：

Payments Received by 08/14/2015 
$0.00
Amount This Period 
+ $57.00

Answer 2

要按照您提到的方式拆分字符串，请使用正则表达式查找初始字母/空格字符，然后使用其余字符。

var s = "Payments Received by 08/14/2015 $0.00";
var re = new Regex("^([a-z ]+)(.+)", RegexOptions.IgnoreCase);
var m = re.Match(s);
if (m.Success)
{
    Console.WriteLine(m.Groups[1]);
    Console.WriteLine(m.Groups[2]);
}

^在开始时找到字符非常重要。
