我如何使用C＃写入Windows事件日志（我遇到某种错误）？

Question

I have written:

.
.
.
//Log exception to the event log
if (!EventLog.SourceExists("PodaHIS")) {
    EventLog.CreateEventSource("PodaHIS", "Application");   
}

EventLog eventLog = new EventLog();
eventLog.Log = "Application";
eventLog.Source = "PodaHIS";
eventLog.WriteEntry(error.ToString(), EventLogEntryType.Error);

I have also enabled read permission to LOCALMACHINE\\ASPNET.

And in return i get:

The source was not found, but some or all event logs could not be searched. Inaccesible logs: Security.

Does anyone know why this is happening?

Answer 1

HKEY_LOCAL_MACHINE\\System\\CurrentControlSet\\Services\\EventLog

What is need to do was grant the " Security " sub key of the EventLog Key read permission. After that i restarted my IIS.

Answer 2

如果您在要向其中写入事件日志的框上具有权限，则可以运行我编写的脚本 。

Answer 4

I think that a higher level of access is required to create a source in the event log. It's possible that the reference to Security log is coincidental and it is just reporting that as a possible cause. If you go in as an administrator and create the PodaHIS source yourself, you might then find that it can write to it.

What it your deployment environment? If it is Vista/Server 2008 then adding worker account into Administrators group won't work due to UAC.

This link explains the problem in details. But I would recommend try creating an event source manually so ASPNET won't need to create it...
