Regex.Split（），以逗号，空格或分号分隔的字符串 [英] Regex.Split() on comma, space or semi-colon delimitted string

问题描述

我正在尝试分割一个字符串，该字符串可以用逗号，空格或分号分隔。每个分隔符后也可以包含一个或多个空格。例如

I'm trying to split a string that can either be comma, space or semi-colon delimitted. It could also contain a space or spaces after each delimitter. For example

22222,11111,23232 
OR
22222, 11111, 23232 
OR
22222;     11111; 23232
OR
22222 11111 23232 

其中任何一个都会产生一个数组具有三个值 [ 22222， 11111， 23232]

Any one of these would produce an array with three values ["22222","11111","23232"]

到目前为止，我有 var值= Regex.Split（ 22222，11111，23232，@ [\\s，;] +）但这会生成一个包含第二个和第三个数组包括空格的值，如下所示：

So far I have var values = Regex.Split("22222, 11111, 23232", @"[\\s,;]+") but this produces an array with the second and third values including the space(s) like so:

["22222"," 11111"," 23232"]

推荐答案

您有两种可能：

• Regex.Split


• String.Split

• Regex.Split
• String.Split

在在这种情况下，您想按特定的定界符分割字符串。为此目的创建了 String.Split 。此方法将比 Regex.Split 。

In this case, you want to split your string by specific delimiters caracters. String.Split has been created for this special purpose. This method will be faster than Regex.Split.

char[] delimiters = new [] { ',', ';', ' ' };  // List of your delimiters
var splittedArray = myString.Split(delimiters, StringSplitOptions.RemoveEmptyEntries);
