What kind of expression that evaluates to a type would you have there? Something with reflection? You could probably use reflection to invoke the method with an expression of the type Type, but I'm not actually sure. Reflection can do a lot though, so why not..
edit: If all else fails, there is still the possibility to compile and run a piece of code that has been generated at runtime. But I wouldn't use that except in emergencies. It's not exactly fast, or a clean design.

A method which may prove useful is Type.MakeGenericType[^]. I don't fully understand it, but it seems to be a step in the right direction - getting the type of a generic type (without the type specifiers), then calling MakeGenericType on the result to get a dynamically set Type

Man thanks a lot, it did worked:

Type cons = typeof(List<>).MakeGenericType(Tipo);

object _list = cons.Assembly.CreateInstance(cons.FullName);

+1 for you!

This code creates a generic type and instatiate an object of that type in runtime using MakeGenericType as Computafreak mentioned. I was going to post it last night but I forgot and fell asleep. But now I know you want it in .net 2.0 I have to remove var and new[]

static void Main(string[] args)
{
    Type t = typeof(List<> );
    Type gt = t.MakeGenericType(GetTypes());
    object gtObj = Activator.CreateInstance(gt);
}

private static Type[] GetTypes()
{
    return new Type[] { typeof(int) };
}

But gtObj is returned as an object (but it is a List<int>). The problem is that you will probably have to use reflection.

You're welcome. I read your other post[^] and you don't have to use the FullName of the Type, you can just pass the Type directly which is faster IMHO.

How to implement a timer in Windows Service correctly?

astv15-Jul-09 5:16

In this windows service, I have a log configured to record the Windows Service Start and Stop state and the process triggered by a timer. The process is sending an email notification once a day.

Currently, the Windows Service Start and Stop state is recoding successfully in the log. The email notification process triggered by the timer however is not doing anything. Any help is much appreciated.

See my script below:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Diagnostics;
using System.ServiceProcess;
using System.Text;
using System.IO;
using System.Timers;

namespace IRISEmailNotifier
{
public partial class IRISEmailNotifier : ServiceBase
{
public IRISEmailNotifier()
{
InitializeComponent();
}

protected override void OnStart(string[] args)
{
try
{
LogEntry le = new LogEntry("Start - " + DateTime.Now.ToString() + "\n");

this.timer1.Interval = 10000;
this.timer1.Enabled = true;
this.timer1.Tick += new EventHandler(timer1_Tick);
}
catch (Exception ex)
{
LogEntry le = new LogEntry(ex.ToString());
}
}

void timer1_Tick(object sender, EventArgs e)
{
try
{
LogEntry le = new LogEntry("Send Email - " + DateTime.Now.ToString() + "\n");
}
catch (Exception ex)
{
LogEntry le = new LogEntry(ex.ToString());
}
}

protected override void OnStop()
{
try
{
LogEntry le = new LogEntry("Stop - " + DateTime.Now.ToString() + "\n");

this.timer1.Enabled = false;
}
catch (Exception ex)
{
LogEntry le = new LogEntry(ex.ToString());
}
}

private void SendEmailNotification()
{
try
{
LogEntry le = new LogEntry("Send Email - " + DateTime.Now.ToString() + "\n");
}
catch (Exception ex)
{
LogEntry le = new LogEntry(ex.ToString());
}
}
}
}

Are you using a Windows Form timer? IIRC, System.Timers.Timer has an elapsed event, not a tick event but I could be wrong.

Well, I'm guessing your windows service doesn't have a form so I'm not sure Windows.Forms.Timer would work, if I were you I'd try using System.Timers.Timer, it might not solve your problem but you never know...

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
