C#日志记录设计与实现（BenXHLog）
C#日志记录设计与实现
日志记录：
日志记录在程序设计开发过程中，是非常重要的，可以供调试和记录数据，虽然说有开源的强大日志管理系统，比如apache的Log4Net，功能可谓强悍，但是有时候，不需要这么大的日志，只需要显示和文件记录就可以了，没必要用这么重的日志系统，那么就需要自己来写，如下就是一个简单的日志记录和显示模块的设计和实现，如有不足，还望见谅！废话不多，直入主题。
笨小孩日志：BenXHLog
类文件设计：
文件结构简单，类图就不画了，细心的已经发现了，这就是一个简单工厂模式，
程序代码：

using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace BenXH.Log.Log { public class LogFactory:ILogFactory { ////// 创建日志实例 /// /// /// public ILog GetLog(string name) { return new Log(name); } } }
LogUtil日志格式化
1 using BenXH.Log.Common; 2 using System; 3 using System.Collections.Generic; 4 using System.Linq; 5 using System.Text; 6 7 namespace BenXH.Log.Log 8 { 9 internal class LogUtil 10 { 11 ///12 /// 格式式化Log信息 13 /// 14 /// 15 /// 16 /// 17 /// 18 /// 19 private static string GetLogString(string name, string logType, string log) 20 { 21 return String.Format("[{0}]{1}-{2}: {3}", DateTime.Now.ToString("HH:mm:ss"),name, logType, log); 22 } 23 24 /// 25 /// 获得日志要保存的路径 26 /// 27 /// 28 /// 29 /// 30 private static string GetLogPath(string name, string logType) 31 { 32 string path = AppDomain.CurrentDomain.BaseDirectory+"Log"; 33 if (!System.IO.Directory.Exists(path)) 34 { 35 System.IO.Directory.CreateDirectory(path); 36 } 37 38 return System.IO.Path.Combine(path,String.Format("{0}_{1}_{2}.log",DateTime.Now.ToString("yyyy-MM-dd"),name,logType)); 39 } 40 41 public static void WriteLogFile(string name, string logType, string log) 42 { 43 string logPath = GetLogPath(name, logType); 44 45 FileUtil.WriteAppend(logPath,log); 46 } 47 } 48 }
最后就是一个日志信息的显示和文件的存储 FileUtil
1 using System; 2 using System.Collections.Generic; 3 using System.IO; 4 using System.Linq; 5 using System.Text; 6 7 namespace BenXH.Log.Common 8 { 9 public static class FileUtil 10 { 11 ///12 /// 追加内容到指定文件中 13 /// 14 /// 15 /// 16 public static void WriteAppend(string filePath, string content) 17 { 18 WriteAppend(filePath,new string[]{content}); 19 } 20 21 public static void WriteAppend(string filePath, string[] contents) 22 { 23 //System.IO.StreamWriter sr = new System.IO.StreamWriter(filePath, true); 24 //foreach (string c in contents) 25 //{ 26 // sr.WriteLine(c); 27 //} 28 //sr.Flush(); 29 //sr.Close(); 30 31 using (FileStream fs = new FileStream(filePath, FileMode.OpenOrCreate, FileAccess.Write, FileShare.ReadWrite)) 32 { 33 fs.Seek(fs.Length, SeekOrigin.Current); 34 35 string content = String.Join(Environment.NewLine, contents) + Environment.NewLine; 36 37 byte[] data = System.Text.Encoding.UTF8.GetBytes(content); 38 39 fs.Write(data, 0, data.Length); 40 41 fs.Close(); 42 } 43 } 44 } 45 }
测试代码：
Test.cs
1 class Test 2 { 3 static void Main(string[] args) 4 { 5 //日志BenXH的Debug信息 6 new BenXH.Log.Log.LogFactory().GetLog("BenXH").Debug(true, "Hello"); 7 new BenXH.Log.Log.LogFactory().GetLog("BenXH").Debug(true, "World"); 8 9 //日志BenXH的info信息 10 new BenXH.Log.Log.LogFactory().GetLog("BenXH").Info(true, "Hello"); 11 new BenXH.Log.Log.LogFactory().GetLog("BenXH").Info(true, "BenXH"); 12 Console.Read(); 13 } 14 }
运行结果：
文件：程序运行根目录下Log文件夹
Log文件夹下新创建俩个文件DEBUG和INFO
文件：2017-07-29_BenXH_DEBUG.log
文件内容
[17-07-29 16:01:26]>>Hello
[17-07-29 16:01:26]>>World
文件：2017-07-29_BenXH_INFO.log
文件内容：
[17-07-29 16:01:26]>>Hello
[17-07-29 16:01:26]>>BenXH
