Question

我需要在标准短语中捕获N个电话号码和姓名： “请写下我的电话：999999 - Vinicius Lacerda Andrioni，我已经90岁了。” “请写下我的电话：888888 - michael jordan，我已经60岁了。”

输出应该是： string：999999,888888 字符串：Vinicius Lacerda Andrioni，michael jordan

string pattern = @"phone: (?<after>\w+)";
string input = "Please write down my phone: 999999 - Vinicius Lacerda Andrioni and I have 90 years old.";
MatchCollection matches = Regex.Matches(input, pattern);
for (int i = 0; i < matches.Count; i++)
{ 
    MessageBox.Show(matches[i].Groups["after"].ToString());
}

输出：999999 输出：???

Answer 1

这更简单：

String Input = "Please write down my phone: 999999 - Vinicius Lacerda Andrioni and I have 90 years old.";

String[] Results = Input.Split(new String[] {": ", "- ", " and" }, StringSplitOptions.None);

// of course you'll want to add error checking....
MessageBox.Show(Results[1]);
MessageBox.Show(Results[2]);

Answer 2

试试这个：

Regex regex = new Regex(@"phone:\s?(?<phone>\w+)\s?[-]\s?(?<name>.*)\s?and");
string input = "Please write down my phone: 999999 - Vinicius Lacerda Andrioni and I have 90 years old.";
var v= regex.Match(input);
Console.WriteLine("Phone = " + v.Groups["phone"].ToString() + " Name = " + v.Groups["name"].ToString());

据我了解，您希望从此标准格式中获取名称和电话号码。因此，只需将表达式扩展为包含名称部分的第二个组，然后以与手机相同的方式检索值。
