EnterpriseLibrary4 自己封装程序集实现log打印
注意：1）要引用响应的程序集，必须是41的
2）配置文件
using Microsoft.Practices.EnterpriseLibrary.Common.Configuration;using Microsoft.Practices.EnterpriseLibrary.Common.Configuration.ObjectBuilder;using Microsoft.Practices.EnterpriseLibrary.Logging;using Microsoft.Practices.EnterpriseLibrary.Logging.Filters;using Microsoft.Practices.EnterpriseLibrary.Logging.Instrumentation;using System.Collections.Generic;using System.Configuration;using System.Diagnostics;
namespace Core{ public class MicroLogger { // Fields private const int DefaultEventId = 1; private const int DefaultPriority = -1; private const TraceEventType DefaultSeverity = TraceEventType.Information; private const string DefaultTitle = ""; private static readonly ICollection<string> emptyCategoriesList = new List<string>(0); private static LogWriterFactory factory = new LogWriterFactory(ConfigurationSourceFactory.Create()); private static object sync = new object(); private static volatile LogWriter writer; //第三步 public static void Write(LogEntry log) { Writer.Write(log); } //第一步 public static void Write(object message) { Write(message, emptyCategoriesList, -1, 1, TraceEventType.Information, "", null); } #region public static void Write(object message, ICollection<string> categories) { Write(message, categories, -1, 1, TraceEventType.Information, "", null); } //第二步 public static void Write(object message, ICollection<string> categories, int priority, int eventId, TraceEventType severity, string title, IDictionary<string, object> properties) { LogEntry log = new LogEntry { Message = message.ToString(), Categories = categories, Priority = priority, EventId = eventId, Severity = severity, Title = title, ExtendedProperties = properties }; Write(log); } //第四步 // Properties public static LogWriter Writer { get { if (writer == null) { lock (sync) { if (writer == null) { try { writer = factory.Create(); } catch (ConfigurationErrorsException exception) { TryLogConfigurationFailure(exception); throw; } } } } return writer; } } }}
对应的配置文件，可以通用
