Beyond web logs

Here is an excellent piece of code to enable you guys out there to specify ULS log entries in SharePoint 2010:

public static void LogULS(TraceSeverity level, string message)
        {
            string traceSeverityName = null;
            string eventSeverityName = "None";
            uint tag = 123;
            string area = "Custom Area";
            string categoryName = "Custom Category";

            // ** Map the SP2007 TraceSeverity Enum to the SP2010 ones
            switch (level)
            {
                case TraceSeverity.High:
                case TraceSeverity.Medium:
                case TraceSeverity.Monitorable:
                case TraceSeverity.Unexpected:
                    traceSeverityName = "Unexpected";
                    break;
                case TraceSeverity.Verbose:
                case TraceSeverity.VerboseEx:
                    traceSeverityName = "Medium";
                    break;
                default:
                    // ** Anything else is mapped 1:1
                    traceSeverityName = level.ToString();
                    break;
            }

            // ** Load the SharePoint 2010 version of Microsoft.SharePoint
            Assembly assembly = Assembly.Load("Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c");

            // ** Get SPDiagnosticsService.Local
            Type spDiagnosticsServiceType = assembly.GetType("Microsoft.SharePoint.Administration.SPDiagnosticsService");
            object service = spDiagnosticsServiceType.GetProperty("Local", BindingFlags.Static | BindingFlags.Public).GetValue(
                Activator.CreateInstance(spDiagnosticsServiceType), null);

            // ** Get the correct enum value
            Type eventSeverityType = assembly.GetType("Microsoft.SharePoint.Administration.EventSeverity");
            object eventSeverity = eventSeverityType.GetField(eventSeverityName).GetValue(null);
            Type traceSeverityType = assembly.GetType("Microsoft.SharePoint.Administration.TraceSeverity");
            object traceSeverity = traceSeverityType.GetField(traceSeverityName).GetValue(null); ;

            // ** Create a new DiagnosticsCategory
            Type diagnosticsCategoryType = assembly.GetType("Microsoft.SharePoint.Administration.SPDiagnosticsCategory");
            Object diagnosticsCategory = Activator.CreateInstance(diagnosticsCategoryType, new Object[] { categoryName,
        traceSeverity, eventSeverity});

            // ** Set the area
            Type diagnosticsAreaType = assembly.GetType("Microsoft.SharePoint.Administration.SPDiagnosticsArea");
            Object diagnosticsArea = Activator.CreateInstance(diagnosticsAreaType, new Object[] { area, null });
            diagnosticsCategoryType.GetProperty("Area").SetValue(diagnosticsCategory, diagnosticsArea, null);

            // ** Execute the WriteTrace method
            spDiagnosticsServiceType.GetMethod("WriteTrace").Invoke(service, new object[] { tag, diagnosticsCategory,
        traceSeverity, message, null });
        }

enJoY!
