C# event log

Question

Hi guys
I’m trying to write a simple event log but i confront with “System.Security.SecurityException: The source was not found...”
and i searched a lot but couldn’t find an efficient solution, I really really appreciate if someone help me with that 🙏🏽
I know that the source needed to be created and the key must be registered but what is the key and
How should i do that?

String source =“DemoTestApplication”;
String log = “DemoEventLog”;
EventLog demolog=new EventLog(log);
demolog.Source=source;
demolog.writeEntry(“This is the first message to the log”,EventLogEntryType.Information);

Is this a Windows event log?
