log4net的配置与使用(3)

 一个调用log4net和LoggingService 的示例：

using ISharpDevelop.Core;

using System;
using System.Diagnostics;
using System.IO;
using System.Reflection;
using System.Windows.Forms;

using ICSharpCode.Core;


namespace LoggerTest
...{
    public class Main
    ...{
        static string[] commandLineArgs = null;

        public static string[] CommandLineArgs
        ...{
            get
            ...{
                return commandLineArgs;
            }
        }

        public static void Main(string[] args)
        ...{
#if DEBUG
            if (Debugger.IsAttached)
            ...{
                Run(args);               
                return;
            }
#endif
            // Do not use LoggingService here (see comment in Run(string[]))
            try
            ...{
                Run(args);
            }
            catch (Exception ex)
            ...{
                try
                ...{
                    HandleMainException(ex);
                }
                catch (Exception loadError)
                ...{
                    // HandleMainException can throw error when log4net is not found
                    MessageBox.Show(loadError.ToString(), "Critical error (Logging service defect?)");
                }
            }
        }

        static void HandleMainException(Exception ex)
        ...{
            LoggingService.Fatal(ex);
            try
            ...{
                MessageBox.Show(ex.ToString(), "Unhandled exception terminated");
            }
            catch
            ...{
                MessageBox.Show(ex.ToString(), "Critical error (cannot use ExceptionBox)");
            }
        }

        static void Run(string[] args)
        ...{
            Application.SetCompatibleTextRenderingDefault(false);

            RunApplication();
        }

        static void RunApplication()
        ...{
            LoggingService.Info("Starting SharpDevelop...");
         
            try
            ...{

                for (int i = 0; i < 10; i++)
                ...{
                    LoggingService.Warn(i.ToString());
                }
            }
            finally
            ...{
                LoggingService.Info("Leaving RunApplication()");
            }
        }
    }
}
