Writing to ULS from within C#

Writing to ULS from within C#

Event Receivers and Feature Receivers are notoriously hard to debug.  Here’s a little gem to ease your debugging migraines:

Here’s the function I use, just to simplify subsequent calls:

private void LogOut(TraceSeverity Level, string OutStr)
        {
            SPDiagnosticsService.Local.WriteTrace(0, new SPDiagnosticsCategory("SuperRouter Updated", Level, EventSeverity.Error), TraceSeverity.Unexpected, OutStr, null);
        }

Here’s  what the call looks like. Note you can set the severity level.  I sprinkle these throughout the code and dump data etc throughout

LogOut(TraceSeverity.High, "Item Updated Event Trapped!");

Here’s the reference to use in the code:

using Microsoft.SharePoint.Utilities;
using Microsoft.SharePoint.Administration;

If you’d like a class to reuse, here it is:

 public class MyLogger
    {
        public static void LogOut(TraceSeverity Level, string OutStr)
        {
            SPDiagnosticsService.Local.WriteTrace(0, new SPDiagnosticsCategory("JoelER", Level, EventSeverity.Error), TraceSeverity.Unexpected, OutStr, null);
        }
    }
