生成日志文件操作
c# 创建日志文件，非常的简单，这里也写一下记录吧！！！
直接上代码：
1 #region 当前文件输出路径 2 public static string SYSTEM_OUTLOG_FILEDIRECTORY = Directory.GetCurrentDirectory() + "/logfile/"; 3 4 #endregion 5 6 #region 公有方法 7 8 /// <summary> 9 /// 给日志文件写入信息 10 /// </summary> 11 /// <param name="info">需要写入的信息</param> 12 /// <returns>true:表示写入成功</returns> 13 public static bool Write(string needWriteInfo) 14 { 15 bool success = false; 16 if (File.Exists(LogPath)) 17 { 18 //追加文件 19 using (FileStream fs = new FileStream(LogPath, FileMode.Append, System.IO.FileAccess.Write, FileShare.ReadWrite)) 20 { 21 using (StreamWriter sw = new StreamWriter(fs, Encoding.UTF8)) 22 { 23 //开始写入 24 sw.WriteLine(DateTime.Now + " " + needWriteInfo); 25 success = true; 26 } 27 } 28 } 29 else 30 { 31 using (FileStream fs = new FileStream(LogPath, FileMode.CreateNew, System.IO.FileAccess.ReadWrite, FileShare.ReadWrite)) 32 { 33 using (StreamWriter sw = new StreamWriter(fs, Encoding.UTF8)) 34 { 35 //开始写入 36 sw.WriteLine(DateTime.Now + ": " + needWriteInfo); 37 success = true; 38 } 39 } 40 } 41 42 return success; 43 } 44 45 /// <summary> 46 /// 读取日志文件的信息 47 /// </summary> 48 /// <param name="path">文件路径</param> 49 /// <returns>返回读取的信息</returns> 50 public static string Read(string path) 51 { 52 string contents = string.Empty; 53 if (File.Exists(path)) 54 { 55 using (FileStream fs = new FileStream(path, FileMode.Open, System.IO.FileAccess.Read, FileShare.ReadWrite)) 56 { 57 using (StreamReader sr = new StreamReader(fs, Encoding.UTF8)) 58 { 59 //开始读取 60 contents = sr.ReadToEnd(); 61 } 62 } 63 } 64 return contents; 65 } 66 67 /// <summary> 68 /// 清除日志文件的信息 69 /// </summary> 70 /// <param name="path">文件的路径</param> 71 /// <returns>true:表示清空成功</returns> 72 public static bool Clear(string path) 73 { 74 bool success = false; 75 if (File.Exists(path)) 76 { 77 using (FileStream fs = new FileStream(path, FileMode.Open, System.IO.FileAccess.ReadWrite, FileShare.ReadWrite)) 78 { 79 fs.Seek(0, SeekOrigin.Begin); 80 fs.SetLength(0); 81 success = true; 82 } 83 } 84 return success; 85 } 86 87 /// <summary> 88 /// 删除日志文件 89 /// </summary> 90 /// <param name="path">文件的路径</param> 91 /// <returns>true:表示删除成功</returns> 92 public static bool Delete(string path) 93 { 94 bool success = false; 95 if (File.Exists(path)) 96 { 97 File.Delete(path); 98 success = true; 99 } 100 return success; 101 } 102 103 #endregion 104 105 #region 私有方法 106 107 /// <summary> 108 /// 日志文件存放路径 109 /// </summary> 110 private static string LogPath 111 { 112 get 113 { 114 string OutPath = SYSTEM_OUTLOG_FILEDIRECTORY; 115 116 if (!Directory.Exists(OutPath)) 117 { 118 Directory.CreateDirectory(OutPath); 119 } 120 121 return OutPath + DateTime.Today.ToString("yyyy-MM-dd") + ".txt"; 122 } 123 } 124 125 #endregion
