Join in AssemblyInfo.cs in class library common

[Assembly:log4net. Config.xmlconfigurator (configfile = "Log4net.config", Watch = True)]

To create a new class

public class Log {private static log4net. ILog log = log4net.        Logmanager.getlogger ("Ikangdentallog"); public static void Debug (String message) {if (log. isdebugenabled) {log.

2 A simple logging

Public  class log    {        ///<summary>///write log (for tracking)///        </summary> public       static void Writelog (String Strmemo)        {            string filename = HttpContext.Current.Request.PhysicalApplicationPath;            Saved path            string time = DateTime.Now.ToString ("Yyyy-mm-dd");            filename = filename + "/log/" + "+" "+ Time +". txt ";            StreamWriter sr = null;            Try            {                if (! File.exists (filename))                {                    sr = file.createtext (filename);                }                Else                {                    sr = file.appendtext (filename);                }                Sr. WriteLine (Strmemo);            }            Catch            {            }            finally            {                if (sr! = NULL)                    Sr. Close ();}}    }

Use the time Log.writelog ("XXX");
