c# 简单日志记录类 log
共享一下很久写的一个日志记录类
网上的日志记录DLL,复杂繁多,最典型的就是log4net
但是往往你又不需要这么高级的东东(唉!配置麻烦),干脆自己弄一个简单的日志记录工具类,还算凑合着用(主要是并发记录日志和多线程的问题).
喜欢的就拿去用吧! 以后有时间把它改成多线程的就完美了。
上代码:
using System; namespace NatureSex.CommonTool.Log { /// <summary> /// 日志等级 /// </summary> public enum LoggerWarnLevel { /// <summary> /// 日常等级 /// </summary> Info = 1, /// <summary> /// 错误等级 /// </summary> Error = 2 } }
