C#: GUI to display realtime messages from Windows Service

阅读更多关于 C#: GUI to display realtime messages from Windows Service

I've written a C# windows service which can write messages to a custom EventLog or to any number of files. These messages are all marked with some priority (so, for example, only ERRORs and WARNINGs get stored in the EventLog, but if desired a lot more can be stored to a file).

问题 The System.Diagnostics.EventLog class provides a way to interact with a windows event log. I use it all the time for simple logging... System.Diagnostics.EventLog.WriteEntry("MyEventSource", "My Special Message") Is there a way to set the user information in the resulting event log entry using .NET? 回答1: Toughie ...

问题 I am logging messages using Enterprise Library. I want some of these (typically errors and warnings) to be passed to the Windows event-system). I today route these via entlib.config. This solution works and so far, so good. But, I have more needs than what this solution provides me. I have multiple installations that should log to different logs, but I want their names to be logical and intuitive in the event-viewer. But, the Windows event-system cannot have two categories where the first 8
