C# 生成log文件
public void WriteLog(string strLog) { string sFilePath = AppDomain.CurrentDomain.BaseDirectory + "Log"; string sFileName = DateTime.Now.ToString("yyyyMMdd") + ".txt"; sFileName = sFilePath + "\\" + sFileName; //文件的绝对路径 if (!Directory.Exists(sFilePath))//验证路径是否存在 { Directory.CreateDirectory(sFilePath); //不存在则创建 } FileStream fs; StreamWriter sw; if (File.Exists(sFileName)) //验证文件是否存在,有则追加,无则创建 { fs = new FileStream(sFileName, FileMode.Append, FileAccess.Write); } else { fs = new FileStream(sFileName, FileMode.Create, FileAccess.Write); } sw = new StreamWriter(fs); sw.WriteLine(DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss") + " --- " + strLog); sw.Close(); fs.Close(); }
