如何从List< string>中的字符串中删除数字/数字? [英] How can I remove numbers/digits from strings in a List<string>?

问题描述

我有一个字符串列表:

List<string> _words = ExtractWords(strippedHtml);

_words 包含1799个索引；每个索引中都有一个字符串.

_words contains 1799 indexes; in each index there is a string.

某些字符串仅包含数字，例如:

Some of the strings contain only numbers, for example:

"2" 或"2013"​​

我想删除这些字符串，所以最后，列表将仅包含带字母的字符串，而不包含数字.

I want to remove these strings and so in the end the List will contain only strings with letters and not digits.

像"001hello" 这样的字符串是可以的，但是"001" 则不是，应该将其删除.

A string like "001hello" is OK but "001" is not OK and should be removed.

推荐答案

您可以为此使用LINQ:

You can use LINQ for that:

_words = _words.Where(w => w.Any(c => !Char.IsDigit(c))).ToList();

这会过滤掉完全由数字组成的字符串以及空字符串.

This would filter out strings that consist entirely of digits, along with empty strings.
