C# 用于选择特定文本的正则表达式

在C#中使用正则表达式。

你能帮忙吗

使用系统；
班级计划
{
静态void Main（）
{
string dummyString=“虚拟警报：3/3警报已解决
；问题警报：您是否遇到问题，或者您的音量是否低于正常值？”+
“是警报将于2018年9月1日下午1:08和10:00关闭；问题警报：您是否喝了更多液体？”+
“是警报于2019年9月10日下午1:08关闭，2017年9月10日进行了Ram支持访问，重量90.2kg（干）。”+
“达到TW。无外周水肿。根据患者病史，血压在常规范围内。尿量1050ml。此时无PO液体限制。”+
“患者确实忘记了提交流程图。在一周内通过流程图审查监控UF趋势。Michelle Mayhew Smith，RN。”；
//用绳子，分开
var splitted=dummyString.Split（新字符串[]{“
；”}，StringSplitOptions.None）；
Console.WriteLine（拆分[Splited.Length-1]）；
//使用String.LastIndexOf和String.Substring
int lastIndex=dummyString.LastIndexOf（
；）；
Console.WriteLine（dummyString.Substring（lastIndex+5））；
}
}

写两次：

2017年9月10日进行的Ram支持访问，重量90.2kg（干燥）。实现了TW。无周围水肿。根据患者病史，血压在常规范围内。尿量1050ml。此时无PO油液阻塞。病人确实忘了带流程图。在一周内通过流程图审查监控UF趋势。Michelle Mayhew Smith，注册护士

为什么不使用一个用于解析HTML的库，比如HtmlAgilityPack？或按

？你能解释一下吗。。或者举个例子，你显然需要最后一个

。如果是这样，请在下面检查我的答案。关于
+
符号，请注意
“bla”+“bla”
与
“blabla”
相同。
+
所做的就是将这些字符串连接在一起
