[asp.net] System.Security.SecurityException when writing to Event Log

The problem is that the EventLog.SourceExists tries to access the EventLog\Security key, access which is only permitted for an administrator.

A common example for a C# Program logging into EventLog is:

string sSource;
string sLog;
string sEvent;

sSource = "dotNET Sample App";
sLog = "Application";
sEvent = "Sample Event";

if (!EventLog.SourceExists(sSource))
    EventLog.CreateEventSource(sSource, sLog);

EventLog.WriteEntry(sSource, sEvent);
EventLog.WriteEntry(sSource, sEvent, EventLogEntryType.Warning, 234);

However, the following lines fail if the program hasn't administrator permissions and the key is not found under EventLog\Application as EventLog.SourceExists will then try to access EventLog\Security.

if (!EventLog.SourceExists(sSource))
    EventLog.CreateEventSource(sSource, sLog);

Therefore the recommended way is to create an install script, which creates the corresponding key, namely:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EventLog\Application\dotNET Sample App

One can then remove those two lines.

You can also create a .reg file to create the registry key. Simply save the following text into a file create.reg:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EventLog\Application\dotNET Sample App]
