Recently i need write a file watcher. So i need to do based on the file types. I have written little bit of code for doing so. Here is the snippet of this.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading;
using System.IO;
using System.Collections;
namespace ThreadSample
{
class Program
{
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main(string[] args)
{
//
// TODO: Add code to start application here
//
DisplayThread objContainer1 = new DisplayThread(".TXT", DateTime.Now.ToShortDateString());
Thread objThread1 = new Thread(new ThreadStart(objContainer1.DoTXT));
objThread1.Start();
DisplayThread objContainer2 = new DisplayThread(".PDF", DateTime.Now.ToShortDateString());
Thread objThread2 = new Thread(new ThreadStart(objContainer2.DoPDF));
objThread2.Start();
Console.ReadLine();
}
}
class DisplayThread
{
private bool _stopThreads = false;
public bool StopThreads
{
set
{
_stopThreads = value;
}
}
private string strExt, strDateTime = "";
public DisplayThread(string Ext, string datetime)
{
strExt = Ext;
strDateTime = datetime;
}
// shared memory variable between the two threads
private string _threadOutput = "";
/// <summary>
/// Thread 1, Displays that we are in thread 1
/// </summary>
public void DoPDF( )
{
while (_stopThreads == false)
{
lock (this)
{
// Write your PDF LOGIC HERE, Moving files and updating database etc
Console.WriteLine("Display Thread 1 " + strExt);
_threadOutput = "Hello Thread 1";
Thread.Sleep(1000); // simulate a lot of processing
string[] Files = Directory.GetFiles("D://ThreadSample//Files//");
if (Files.Length > 0)
{
foreach (string s in Files)
{
try
{
if (Path.GetExtension(s).ToUpper().Equals(strExt))
{
try
{
// if you date falls between two dates you need to change the condition while comparing.
if (File.GetLastWriteTime(s).ToShortDateString().Equals(strDateTime))
Console.WriteLine(s);
// do the db logic and filemoving etc
}
catch (Exception ex)
{
throw ex;
}
}
}
catch (Exception ex)
{
throw ex;
}
}
}
// we are in thread #1
Console.WriteLine("DoPDF Output --> {0}", _threadOutput + " datetime: -- > " + strDateTime);
}
}
}
/// <summary>
/// Thread 2, Displays that we are in thread 2
/// </summary>
public void DoTXT( )
{
while (_stopThreads == false)
{
lock (this)
{
// Write your TXT LOGIC HERE, Moving files and updating database etc
Console.WriteLine("Display Thread 2 " + strExt);
_threadOutput = "Hello Thread 2";
Thread.Sleep(1000); // simulate a lot of processing
string[] Files = Directory.GetFiles("D://ThreadSample//Files//");
if (Files.Length > 0)
{
foreach (string s in Files)
{
try
{
if (Path.GetExtension(s).ToUpper().Equals(strExt))
{
try
{
// if you date falls between two dates you need to change the condition while comparing.
// Check the File class for rest of useful methods you require..File.GetLastAccessTime
if (File.GetLastWriteTime(s).ToShortDateString().Equals(strDateTime))
Console.WriteLine(s);
// do the db logic and filemoving etc
}
catch (Exception ex)
{
throw ex;
}
}
}
catch (Exception ex)
{
throw ex;
}
}
}
// we are in thread #2
Console.WriteLine("DoTXT Output --> {0}", _threadOutput + " datetime: -- > " + strDateTime);
}
}
}
}
}
I need to check files based on the last modified date. so i am using File class to know the GetLastWriteTime. Instead you can also using System.IO.FileInfo to get the information of LastWriteTime.
string[] Files = Directory.GetFiles("D://ThreadSample//Files//");
System.IO.FileInfo fileInfo = null;
if (Files.Length > 0)
{
foreach (string s in Files)
{
fileInfo = new System.IO.FileInfo(s);
try
{
DateTime LastWT = fileInfo.LastWriteTime;
Console.WriteLine("LastWrite Time" + LastWT.ToShortDateString());
}
catch (Exception ex)
{
throw ex;
}
}
}
Happy coding :-)
