In following few lines, i will teach you how to search content of xml file using .Net. I got solution to this problem after 1 day of practice. So let’s start now.
Consider a file named Search.xml with the following content.
<strong>
</strong><productlist title="ABC">
<product title="ABC-Title">
<doc id="Doc-abc" title="Abc document"/>
</product>
<product title="DEF">
<doc id="Doc-DEF" title="Doc-DEF"/>
</product>
<product title="EFG">
<doc id="EFG Document" description="Document of EFT"/>
</product>
</productlist>
Great, now add a Textbox to take user input for search content. This code can search with product title and document title.
Under a text change property or in any button control’s click event, add the following code. To run this code easily, make
sure you have an empty xml file named SearchResult.xml, datagridview control named SrchList and BindingSource control named BS. This code will display all the matching
result in the gridview.
private void TxtSearchString_TextChanged(object sender, EventArgs e)
{
StringBuilder st= new StringBuilder();
XDocument doc = new XDocument(XDocument.Load("Search.xml"));
var data = from item in doc.Descendants("doc")
select new
{
Ptitle=item.Parent.Attribute("title").Value,
title = item.Attribute("title").Value,
};
DataSet ds = new DataSet();
StringBuilder sr = new StringBuilder();
sr.Append("<product>");
foreach (var p in data)
{
if (p.title.ToUpper().Contains(TxtSearchString.Text.ToUpper()) || p.Ptitle.ToUpper().Contains(TxtSearchString.Text.ToUpper()))
sr.AppendLine("<doc Project-Title =\"" + p.Ptitle.ToString() + "\" Document-Title=\"" + p.title.ToString() + "\" />");
}
sr.Append("</product>");
TextWriter w = new StreamWriter("searchResult.xml");
w.Write(sr.ToString());
w.Flush();
w.Close();
try
{
ds.ReadXml("searchResult.xml");
if (ds.Tables.Count > 0)
{
BS.DataSource = ds.Tables[0];
SrchList.DataSource = BS;
}
}
catch (Exception ex)
{
throw;
}
}

Please, do post your comment regarding the post, and if you find helpful refer to your friend as well. Have a happy coding. .
Shall We start it now??
Well, all you need is a Notepad editor which comes with your Windows and a PHP Apache Server. There are many PHP servers. I prefer you to use Wamp Server. For your 32-bit windows download it Here and if you have 64-bit windows then download it Here.
Double click the installer you just downloaded. On a simple Next-> Next-> Click you will finish the installation of Wamp Server. On your desktop you will find Shortcut named Start WampServer, Open that. To check whether your wamp server is properly installed or not, check on your internet browser by typing http://127.0.0.1 or http://localhost . If you find an error message, your wamp is not installed or started properly. For proper starting At the right side of task bar ( Near the position where clock and date is displayed), click on wamp server and select “Start All Services”. Now we are ready to write and taste our first php page.
1) Write the following code in your notepad.
<html> <head><title>My first Php Page </title></head> <body> <?php echo "This is my first PHP Page"; ?> </body> </html>
2) Save the file into the following directory : C:\wamp\www named test.php or your desire name. Make sure you have installed wamp on C: drive. In case of other drive, replace C by d,e, or your proper drive.
3) Start your internet explorer, and type the following address
http://localhost/test.php
4) If you haven’t made any error on code, you will see the page saying “This is my First PHP Page” to you.
As you see, we can insert php script anywhere inside html just with the <?php ?> tag. All your php code reside within these two tags.
Try it out, for any problem and suggestion you get, please post in comment. I would be happy to help you.
]]>Today, data managed by a program can belong to different data domains: an array, an object graph, an XML document, a database, a text file, a registry key, an e-mail message, Simple Object Access Protocol (SOAP) message content, a Microsoft Office Excel file…. The list is long.
I will guide you through writing a first LINQ Program in C#.Net.
I hope,you can create new console application in Visual Studio. After you have created new console application in Console Application. On Program.cs or Program.vb file, type the following code inside Main function.
string[] greetings = { "Hello World", "Hello LINQ", "Hello PRince" };
var items = from s in greetings where s.EndsWith("LINQ") select s;
foreach (var item in items)
Console.WriteLine(item);
Console.ReadLine();
Since you saw, we can search an array just like you use Database Query. First Line declares Array of string.
Look at the second line, it’s as simple as human language. Don’t wonder, .Net still supoorts var variable type. var can hold data of any type.Okay, Now lets look at the exact query; It takes all the string which End with “LINQ” and store them in variable items.
Foreach reads all values stored in items (Which is collection of String which have “LINQ” on last) as loop.
Console.WriteLine(item); is used to display each string in Console screen.
Having trouble on Typing and Executing Query?
1. On Visual Studio, Go to File Menu.
2. From New, select New Projet. On the Project Dialog, Select Language as Visual C# and project type as Console Application.
3. Give Name/Solution Name as First and click Ok.
4. Open Program.cs file and clear all the lines from Program.cs
5. Copy the code below and enjoy your first LINQ Program.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace First
{
class Program
{
static void Main(string[] args)
{
string[] greetings = { "Hello World", "Hello LINQ", "Hello PRince" };
var items = from s in greetings where s.EndsWith("LINQ") select s;
foreach (var item in items)
Console.WriteLine(item);
Console.ReadLine();
}
}
}
Happy Coding ! ! ! 
Welcome
Hello All, Welcome To My Page. Finally i’ve got what i’d wished to keep on page Thanks to wordpress. This is my very first post on this page. I will soon post various information about Programming on C, C++, Dot net, C#, LINQ, Windows Phone 7, WPF, PHP, and Others. I hope your positive response and comments for the page.
