// Create an event Source, create an application, and use the specified Source as the daily
// Valid event source for the log entry written in the log, and the application is on the local computer. The source name used for p1 registration,
// The Name Of The log written by the p2 source entry
EventLog. CreateEventSource ("TestLog", "log1 ");
}
// Log name
Log1.Log = "log1 ";
// Event source name
Log1.Source = "TestLog ";
// Machine name
Log1.MachineName = ".";
// Write log information, specifying the category
Log1.WriteEntry ("An error has occured", EventLogEntryType. Error );

// Traverse the existing log information
Foreach (EventLogEntry item in log1.Entries)
{
Console. WriteLine (item. Message + "\ t" + item. TimeGenerated );
