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：

LogFactory 日志工厂

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

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         /// <summary>
12         /// 追加内容到指定文件中
13         /// </summary>
14         /// <param name="filePath"></param>
15         /// <param name="content"></param>
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
