I am new to the use of visual studio, I am trying to create a windows service from this tutorial tutorial to create windows service but in TestService.cs I get the error Object reference not established as an instance of an object , below I leave the code
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Diagnostics;
using System.IO;
using System.Linq;
using System.ServiceProcess;
using System.Text;
using System.Threading.Tasks;
namespace WindowsService1
{
public partial class TestService : ServiceBase
{
System.Timers.Timer timeDelay;
int count;
public TestService()
{
InitializeComponent();
timeDelay = new System.Timers.Timer();
timeDelay.Elapsed += new System.Timers.ElapsedEventHandler(WorkProcess);
}
public void WorkProcess(object sender, System.Timers.ElapsedEventArgs e)
{
string process = "Timer Tick " + count;
LogService(process);
count++;
}
protected override void OnStart(string[] args)
{
LogService("Service is Started");
timeDelay.Enabled = true;
}
protected override void OnStop()
{
LogService("Service Stoped");
timeDelay.Enabled = false;
}
private void LogService(string content)
{
FileStream fs = new FileStream(@"d:\TestServiceLog.txt", FileMode.OpenOrCreate, FileAccess.Write);
StreamWriter sw = new StreamWriter(fs);
sw.BaseStream.Seek(0, SeekOrigin.End);
sw.WriteLine(content);
sw.Flush();
sw.Close();
}
}
}
from now thanks for the help.
