Log files are
useful to track any runtime errors and exceptions in all the
applications. Below code will code will get the Message and Pagename as the
input and creates the log file in that date. For that first i have imported
below two namespaces.
using System.Configuration;
using System.IO;
In the below code I
have initialized class with two parameters. One is filename and another one is
to append the message in the log files. If you didn’t pass the second parameter
as true then it won’t append the data in the log file. It means the log
file will contain only the finally inserted message. Complete code to create
log files is here.
public void AddtoLogFile(string Message, string WebPage)
{
string LogPath = ConfigurationManager.AppSettings["LogPath"].ToString();
string filename = "Log_" + DateTime.Now.ToString("dd-MM-yyyy") + ".txt";
string filepath = LogPath + filename;
if (File.Exists(filepath))
{
using (StreamWriter writer = new StreamWriter(filepath,true))
{
writer.WriteLine("-------------------START-------------" + DateTime.Now);
writer.WriteLine("Source
:" + ErrorPage);
writer.WriteLine(Message);
writer.WriteLine("-------------------END-------------" + DateTime.Now);
}
}
else
{
StreamWriter writer = File.CreateText(filepath);
writer.WriteLine("-------------------START-------------" + DateTime.Now);
writer.WriteLine("Source
:" + ErrorPage);
writer.WriteLine(Message);
writer.WriteLine("-------------------END-------------" + DateTime.Now);
writer.Close();
}
}
