推荐答案

这很简单.您可以自己使用IndexOf和Replace或Loop的组合，并将仅有效字符复制到新字符串中.你卡在哪一部分?


您可以尝试:

This is very simple. You can use a combination of IndexOf and Replace or Loop through it yourself and copy only the valid characters to a new string. What part are you stuck on?


You can try:

string x = "123.4".Split(''.'')[0];

您确定不想舍入吗?如果是这样，请尝试转换为数字并使用Math.Round，然后转换回字符串.

Are you sure you don''t want to round though? If so, try converting to number and using Math.Round, then convert back to string.
