1.代码
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.IO; using System.Configuration; using System.Reflection; namespace LogHelper.Common { public class LogHelper { private string logFile = ""; /// <summary> /// 不带参数的构造函数 /// </summary> public LogHelper() { try { string logPath = Path.Combine(System.Environment.CurrentDirectory,DateTime.Now.ToString("yyyyMM")); logFile = Path.Combine(logPath,DateTime.Now.ToString("yyyyMMdd") + ".txt"); if (!Directory.Exists(logPath)) Directory.CreateDirectory(logPath); if (!File.Exists(logFile)) File.Create(logFile); } catch { } } /// <summary> /// 带参数的构造函数 /// </summary> /// <param name="logFile"></param> public LogHelper(string logFile) { try { this.logFile = logFile; if (!File.Exists(logFile)) { File.Create(logFile); } } catch { } } /// <summary> /// 追加一条信息 /// </summary> /// <param name="text"></param> public void Write(string text) { try { using (StreamWriter sw = new StreamWriter(logFile, true, Encoding.UTF8)) { sw.Write(DateTime.Now.ToString("[yyyy-MM-dd HH:mm:ss] ") + text); } } catch { } } /// <summary> /// 追加一条信息 /// </summary> /// <param name="logFile"></param> /// <param name="text"></param> public void Write(string logFile, string text) { try { using (StreamWriter sw = new StreamWriter(logFile, true, Encoding.UTF8)) { sw.Write(DateTime.Now.ToString("[yyyy-MM-dd HH:mm:ss] ") + text); } } catch { } } /// <summary> /// 追加一行信息 /// </summary> /// <param name="text"></param> public void WriteLine(string text) { try { text += "\\r\\n"; using (StreamWriter sw = new StreamWriter(logFile, true, Encoding.UTF8)) { sw.Write(DateTime.Now.ToString("[yyyy-MM-dd HH:mm:ss] ") + text); } } catch { } } /// <summary> /// 追加一行信息 /// </summary> /// <param name="logFile"></param> /// <param name="text"></param> public void WriteLine(string logFile, string text) { try { text += "\\r\\n"; using (StreamWriter sw = new StreamWriter(logFile, true, Encoding.UTF8)) { sw.Write(DateTime.Now.ToString("[yyyy-MM-dd HH:mm:ss] ") + text); } } catch { } } } }
2.调用
LogHelper.Common.LogHelper logHelper = new Common.LogHelper(); logHelper.WriteLine("你好");
3.路径临时配置位置
在当前位置
string logPath = Path.Combine(System.Environment.CurrentDirectory,DateTime.Now.ToString("yyyyMM")); logFile = Path.Combine(logPath,DateTime.Now.ToString("yyyyMMdd") + ".txt");
