使用正则表达式从字符串中提取多个数字 [英] Using regex to extract multiple numbers from strings

问题描述

我有一个包含两个或多个数字的字符串。以下是一些示例：

I have a string with two or more numbers. Here are a few examples:

"(1920x1080)"
" 1920 by 1080"
"16 : 9"

如何提取分开的数字，例如 1920和

How can I extract separate numbers like "1920" and "1080" from it, assuming they will just be separated by one or more non-numeric character(s)?

推荐答案

基本正则表达式为：

[0-9]+

您将需要使用库检查所有匹配项并获取其值。

You will need to use the library to go over all matches and get their values.

var matches = Regex.Matches(myString, "[0-9]+");

foreach(var march in matches)
{
   // match.Value will contain one of the matches
}
