Remove Duplicates From List in C#
To Remove Duplicates From List can be done by many different ways. You can use Distinct extension method to remove duplicates.
Below program that removes duplicates from the list in C#.
using System;
using System.Collections.Generic;
using System.Linq;
class Program
{
static void Main()
{
// List having duplicate integer elements.
List<int> list = new List<int>();
list.Add(7);
list.Add(2);
list.Add(5);
list.Add(5);
list.Add(2);
list.Add(3);
list.Add(7);
// Get distinct elements and convert again into a list.
List<int> distinct = list.Distinct().ToList();
foreach (int value in distinct)
{
Console.WriteLine("Distinct : {0}", value);
}
}
}
OR
You can use LINQ to object to remove duplicates from list,
using System;
using System.Collections.Generic;
using System.Linq;
class Program
{
static void Main()
{
// List having duplicate string elements.
List<string> list = new List<string>();
list.Add("A");
list.Add("A");
list.Add("C");
list.Add("D");
list.Add("B");
list.Add("A");
list.Add("E");
list.Add("E");
// Get distinct elements.
var distinct = (from item in list orderby item select item).Distinct();
foreach (string value in distinct)
{
Console.WriteLine("Distinct : {0}", value);
}
}
}

Sort Integer and String Array in C#
Example 1: Sort Int[] Array
This example int[] array that you have in your C# program. You can call static Array.Sort Method and use it to sort a integer array in place. The result is an ascending order of numbers.
using System;
using System.Collections.Generic;
using System.Text;
class Program
{
static void Main(string[] args)
{
int[] data = { 999,9,19,555,5,18,399};
Array.Sort(data);
foreach (int i in data)
Console.WriteLine(i);
Console.ReadLine();
}
}
Example 2: Sort string[] Array
This example string[] array that you have in your C# program. You can call static Array.Sort Method and use it to sort a string array in place. The result is an alphabetical sort.
using System;
class Program

{
string[] str = new string[]
{
"British",
"Indian",
"American",
"Chinese",
"Malaysians"
};
Array.Sort(str);
foreach (string s in str)
Console.WriteLine(s);
Console.ReadLine();
}
Example 3: Sort string Array with LINQ

var desc = from s in str
orderby s descending
select s;
foreach (string s in desc)
Console.WriteLine(s);
Console.ReadLine();
}
}
Example 5: Sort List
List<string> is a generic List collection of strings. It is stored as a string array. We can use LINQ exact same way we used in Example 3 and 4.

Changing Master Page at Runtime
Solution 1:
Changing Master Page at Runtime by user code.
Many times we have to change Master Page at Runtime by user code. Page_PreInit event will execute just before that page is render. We can write a simple code in Page_PreInit event like below,
protected void Page_PreInit(object sender, EventArgs e)
{
if (Membership.GetUser() == null) //check if the user is logged in or not
this.MasterPageFile = "~/General.master";
else
this.MasterPageFile = "~/MyPortal.master";
}
Solution 2:
Changing Master Page at Runtime by user code based on users roles and responsibilities.
Sometimes there different types of users for the same application. All users have their own roles and responsibilities for the application.
For e.g There are different types of users for my portal application. They all should be able to browse their role related master page.
1. Executive Directors
2. Admin
3. Investment Officers
4. Users
For above portal application senerio we can write code in content Page_PreInit event like below,
protected void Page_PreInit(object sender, EventArgs e)
{
int varRole = 0;
int.TryParse(Session["Role"].ToString(),out varRole);
if (varRole == 1)
{
this.MasterPageFile = "ExecDir.master";
}
if (varRole == 2)
{
this.MasterPageFile = "Admin.master";
}
if (varRole == 3)
{
this.MasterPageFile = "Officer.master";
}
if (varRole == 4)
{
this.MasterPageFile = "User.master";
}
}

Javascript Alert message from code behind in ASP.NET
We all know that we can display javascript alert message from code behind in ASP.NET using Page.ClientScript.RegisterStartupScript.
Page.ClientScript.RegisterStartupScript(this.GetType(),"myscript","alert('hello world!');");
However, above method can break under ASP.NET AJAX environment. For AJAX we need to use ScriptManager.RegisterStartupScript. Below code displays javascript alert message both in AJAX environment and on regular page as well.
ScriptManager.RegisterStartupScript(this,this.GetType(),"myscript","alert('hello world!');",true);
For more information on ClientScriptManager.RegisterStartupScript Method you can visit,
Get Assembly Name

Sending email from ASP.NET
Sending Email from an ASP.NET web application is a simple task.
For sending Email from ASP.NET web application we need to add one namespace,
using System.Net.Mail;
After this we can create a method , sendEmail().
public void sendEmail()
{
MailMessage message = new MailMessage();
message.From = new MailAddress("test@gmail.com");
message.To.Add(new MailAddress("test1@gmail.com"));
message.Subject = "Sending an email from ASP.NET web application";
message.Body = "Your Email Content here…";
SmtpClient client = new SmtpClient();
client.Host = "Give your mail server IP";
client.Port = Put port number;
client.Send(message );
}
You can use this function anywhere from application.

Validate Email Address using RegularExpressionValidator
Sometimes there might be the requirement to Validate Email Address using RegularExpressionValidator in application.
If Email address Textbox on your form is Required Field, then try to use following code on your page.
<asp:TextBox ID="txtEmail" runat="server" />
<asp:RequiredFieldValidator ID="txtEmailRequired" runat="server"
ControlToValidate="txtEmail"
Text="* Required"
Display="Dynamic" />
<asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server"
ErrorMessage="eg: emailAdd@domain.com"
ControlToValidate="txtEmail"
ValidationExpression="\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*"
Display="Dynamic">
</asp:RegularExpressionValidator>
If Email address Textbox on your form is NOT a Required Field, then you can use following code on your page.
<asp:TextBox ID="txtEmail" runat="server" />
<asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server"
ErrorMessage="eg: emailAdd@domain.com"
ControlToValidate="txtEmail"
ValidationExpression="\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*"
Display="Dynamic">

Remove Querystring item in ASP.NET
If we try to remove/delete a query string directly using below code, we will get an error - collection is read-only.
Request.QueryString.Remove("QSname")
In order to solve above error problem, we need to write below code before we remove them.
// reflect to readonly property
PropertyInfo isreadonly = typeof(System.Collections.Specialized.NameValueCollection).GetProperty("IsReadOnly", BindingFlags.Instance | BindingFlags.NonPublic);
// make collection editable
isreadonly.SetValue(this.Request.QueryString, false, null);
// remove
this.Request.QueryString.Remove("QSname");
Generate Random Number in C#
You can use below code to generate a new Random number each time.
Random rd = new Random();
Int32 rdNum = rd.Next();
Response.Write(rdNum.ToString());
Random rd = new Random();
Int32 rdNum = rd.Next();
Response.Write(rdNum.ToString());
Page life Cycle of an ASP.NET page
Following are the events occur during ASP.NET Page Life Cycle:
1)Page_PreInit
2)Page_Init
3)Page_InitComplete
4)Page_PreLoad
5)Page_Load
6)Control Events
7)Page_LoadComplete
8)Page_PreRender
9)SaveViewState
10)Page_Render
11)Page_Unload
Among above events Page_Render is the only event which is raised by page. So we can't write code for this event.
