I want to select:-

            TW achieved. No peripheral edema. BP within routine range per patient history. Urine output 1050ml. No PO fluid restriction at this time.
            Patient did forget to bring in flow sheets.Monitor UF trend with flow sheet review in one week. Michelle Mayhew Smith, RN.

在 C# 中使用正则表达式。

Can you please help.?

using System;

class Program
{
    static void Main()
    {
        string dummyString = "<b>Dummy Alerts: </b>3/3Alerts have been addressed&#10; Question Alert: Have you had problems or are your volumes lower than normal?  " +
            "Yes Alert is closed on 01/09/2018 at 01:08 PM&#10; Question Alert: Have you been drinking more fluid? " +
            " Yes Alert is closed on 10/09/2019 at 01:08 PM&#10;&#10;Ram support visit performed 10/9/17,  Weight 90.2kg (dry). " +
            "TW achieved. No peripheral edema. BP within routine range per patient history. Urine output 1050ml. No PO fluid restriction at this time. " +
            "Patient did forget to bring in flow sheets.  Monitor UF trend with flow sheet review in one week. Michelle Mayhew Smith, RN.";

        // With String.Split    
        var splitted = dummyString.Split(new string[]{"&#10;"}, StringSplitOptions.None);
        Console.WriteLine(splitted[splitted.Length-1]);

        // With String.LastIndexOf & String.Substring
        int lastIndex = dummyString.LastIndexOf("&#10;");
        Console.WriteLine(dummyString.Substring(lastIndex+5));
    }
}

写入两次:
