C# 写日志文件

 public static void WriteLog(string txt)
        {
            try
            {
                string path = Application.StartupPath + @"\log\" + DateTime.Now.ToString("yyyy-MM-dd") + @"\";
                if (!Directory.Exists(path))
                {
                    Directory.CreateDirectory(path);
                }
                path +=  DateTime.Now.ToString("yyyyMMdd") + "-" + DateTime.Now.ToString("HH") + ".txt";
                if (!File.Exists(path))
                {
                    File.Create(path);
                }
                FileStream fs;
                StreamWriter sw;
                fs = new FileStream(path, FileMode.Append);
                sw = new StreamWriter(fs, Encoding.Default);
                sw.Write(DateTime.Now.ToString("HH:mm:ss") + " " + txt + "\r\n");
                sw.Close();
                fs.Close();
            }
            catch (Exception ex)
            {
                WriteLog("程序发生异常（WriteLog）。详情：" + ex.Message);
            }
        }

补充：软件开发 , C# ,

上一个：WPF中模板（ControlTemplate and DataTemplate）
下一个：字符串检索-递归遍历文件夹-excel读取成dataset-结果导入到excel
