Create a new Windows Log on Event Viewer

Question

I need to create a new windows log. I mean this:

I wrote the following line of code:

System.Diagnostics.EventLog.CreateEventSource("My Application Name", "My Custom Log");

It seems it has worked infact this line of code return TRUE

System.Diagnostics.EventLog.SourceExists("My Custom Log");

Even if I try to write in that log, everything works:

EventLog myLog = new EventLog();
myLog.Source = "My Custom Log";
myLog.WriteEntry("Writing to event log.");

But for some reason I still do not see my custom log... I also restarted the pc... What's wrong?

Thank you

You can find your "My Custom Log" in "Registri applicazioni e servizi" — user6522773

You can only create new eventsource there and not in "Registri di Windows" — user6522773

Application logs always appear under Applications and services (Registri applicazioni e servizi).

Note that in order to write to that location, you need to specify both the source and log names properly when initializing the logger:

var myLog = new EventLog(logName: "My Custom Log",
    machineName: ".", source: "My Application Name");

Use EventLogTraceListener Class to create a listener in you App.config file.

> <system.diagnostics>   <trace autoflush="false" indentsize="4">
>     <listeners>
>       <add name="myListener"
>         type="System.Diagnostics.EventLogTraceListener"
>         initializeData="TraceListenerLog" />
>     </listeners>   </trace> </system.diagnostics>

Then go back to you main Program.cs file and create a simple output for windows log.

using System.Diagnostics;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            Trace.WriteLine("Test output");
        }
    }
}

Run the application and go to your event log to check if the Windows log has been created.
