如果以句号结尾但不以包含小数的数字结尾，则拆分句子

Question

我想将我的文本拆分成句子，每个句子以 . 结尾，但不包括带小数点的数字。

我使用了拆分功能。但是它把数字分成两部分，我不想把数字分开。

示例：

My package a mount is 85.5 daily, how can I make use of it. any body has an idea for that. please let me know.

应拆分为：

My package a mount is 85.5 daily, how can I make use of it

any body has an idea for that

please let me know

Answer 1

您可以使用 "period space" 作为分隔符：

string source = "My package amount is 85.5 daily, how can I make use of it. Anybody has an idea for that? Please let me know.";

string[] splits = Regex.Split(source, @"[\.?!]\s+");

这也是以 ! 或 ? 结尾的句子，并采用任意数量的 space 字符（和其他白色 space 字符），最少为一个字符。

如果您想保留句点，请搜索以行尾符号开头的 space：

string[] splits2 = Regex.Split(source, @"(?<=[\.?!])\s+");

Answer 2

Dmitry Bychenko 的回答简单而漂亮，但是它会在 .(dot) 之后丢失一个字符

var regex = new System.Text.RegularExpressions.Regex(@"(?<!\d)\.(?!\d)");
var myText = @"My package a mount is 85.5 daily, how can I make use of it. any body has an idea for that. please let me know.";

Console.WriteLine(regex.Replace(myText, Environment.NewLine));

它只会消耗既没有数字也没有数字的.（点）字符。

如果以句号结尾但不以包含小数的数字结尾，则拆分句子
