code:

using system;

using static System.console;

using System.IO;

namespace findPatientRecords

static void Main(string[] args)

{

string patientld;

char[] splitter = new char[1] { ',' };

            Write("Enter a patients id: ");

            patientId = ReadLine();

            //read all the lines from patgients.txt

            var lines = File.ReadAllLines("patients.txt");

            bool recordFound = false;

            //iterate over all the lines

            foreach (var line in lines)

            {

                //split the line based on ,

                var patientData = line.Split(splitter, StringSplitOptions.RemoveEmptyEntries);

               //search if patient id is as given

                if (patientData[0].Equals(patientId))

                {

                    //display the record and break the loop

                    WriteLine($"Patient Id {patientData[0]}, Name: {patientData[1]}, Bill: {patientData[2]}");

                    recordFound = true;

                    break;

                }

               

            }

            //if record not found then display the given message

            if (!recordFound)

            {

                WriteLine($"No records found for {patientId}");

            }

           

            //you can remove this line of code, this is kept to show output on screen
