Display log file information on a Web page with ASP.NET MVC paging
I have logs stored in a txt file in the following format.
======8/4/2010 10:20:45 AM=========================================

======8/4/2010 10:21:42A M=========================================
Sending information to server
======8/4/2010 10:21:43 AM=========================================
I need to parse these lines into a list where the information betweeen "====" lines is counted as one record to display on web pag开发者_如何学Goe using paging in ASP.NET MVC.
Example: The first record entry would be
======8/4/2010 10:20:45 AM=================================================

I had no luck so far. How can I do it?
Whilst reading in the file could you do a check to see if the line ends with =====
var sBuilder = new StringBuilder()
bool lineEnd = false;
var items = new List<string>();
string currentLine = String.Empty
using(var file = new StringReader("log.txt"))
{
while( (currentLine = file.ReadLine()) != null)
{
if(currentLine.EndsWith("===="))
{
items.Add(sBuilder.ToString());
sBuilder.Clear();
}
else
sBuilder.Append(currentLine);
}
}
It's a bit verbose but might give you some ideas
So... Ignore the verbose code in my other answer. Instead use this two line wonder:
string texty = "=====........"; //File data
var matches = Regex.Matches(texty, @"={6}(?<Date>.+)={41}\s*(?<Message>.+)");
var results = matches.Cast<Match>().Select(m => new {Date = m.Groups["Date"], Message = m.Groups["Message"]});
I always forget about regular expressions.
