本文实例讲述了C#实现自定义windows系统日志的方法。分享给大家供大家参考。具体实现方法如下：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Diagnostics; namespace ConsoleApp { /// <summary> /// 系统日志 /// </summary> public class PackSystemEventLog { /// <summary> /// 错误信息 /// </summary> private static string ErrorInfo { get; set; } /// <summary> /// 创建系统事件日志分类 /// </summary> /// <param name="eventSourceName">注册事件源(比如说这个日志来源于某一个应用程序)</param> /// <param name="logName">日志名称(事件列表显示的名称)</param> /// <returns></returns> public static bool CreateSystemEventLogCategory(string eventSourceName, string logName) { bool createResult = false; try { if (!EventLog.SourceExists(eventSourceName)) { EventLog.CreateEventSource(eventSourceName, logName); } createResult = true; } catch (Exception ex) { createResult = false; ErrorInfo = ex.Message; } return createResult; } /// <summary> /// 删除系统事件日志分类 /// </summary> /// <param name="eventSource">EventName事件源</param> /// <returns></returns> public static bool RemoveSystemEventSourceCategory(string eventSource) { bool createResult = false; try { if (EventLog.SourceExists(eventSource)) { EventLog.DeleteEventSource(eventSource, "."); } createResult = true; } catch (Exception ex) { createResult = false; ErrorInfo = ex.Message; } return createResult; } /// <summary> /// 向系统日志中写入日志 /// </summary> /// <param name="eventSource">事件源</param> /// <param name="msg">写入日志信息</param> /// <param name="type">日志文本分类(警告、信息、错误)</param> /// <returns></returns> public static bool WriteSystemEventLog(string eventSource, string msg, EventLogEntryType type) { bool writeResult = false; try { if (!EventLog.SourceExists(eventSource)) { writeResult = false; ErrorInfo = "日志分类不存在!"; } else { EventLog.WriteEntry(eventSource, msg, type); writeResult = true; } } catch (Exception ex) { writeResult = false; ErrorInfo = ex.Message; } return writeResult; } /// <summary> /// 删除事件源中logName(好像删除了所有的该分类的日志) /// </summary> /// <param name="eventSource"></param> /// <param name="logName"></param> /// <returns></returns> public static bool RemoveSystemEventLog(string eventSource, string logName) { bool removeResult = false; try { if (!EventLog.SourceExists(eventSource)) { removeResult = false; ErrorInfo = "日志分类不存在!"; } else { EventLog.Delete(logName); removeResult = true; } } catch (Exception ex) { removeResult = false; ErrorInfo = ex.Message; } return removeResult; } /// <summary> /// 获取错误信息 /// </summary> /// <returns></returns> public static string GetErrorMessage() { return ErrorInfo; } } }
