GET VS Post Methods

GET Method:
  1. All the name value pairs are submitted as a query string in URL.
  1. It's not secured as it is visible in plain text format in the Location bar of the web browser.
  1. As the data transfers through address bar (URL) there are some restrictions in using space, some characters like ampersand (&) etc in the GET method of posting data. We have to take special care for encoding data if such special characters are present.
  1. Length of the string is restricted.
  1. If method is not mentioned in the Form tag, this is the default method used.
  1. If get method is used and if the page is refreshed it would not prompt before the request is submitted again.
  1. One can store the name value pairs as bookmark and directly be used while sharing with others - example search results.
  1. Data is always submitted in the form of text
  1. If the response of the page is always same for the posted query then use GET example database searches

POST Method:
1. All the name value pairs are submitted in the Message Body of the request.
2. Length of the string (amount of data submitted) is not restricted.
3. Post Method is secured because Name-Value pairs cannot be seen in location bar of the web browser.
4. If post method is used and if the page is refreshed it would prompt before the request is resubmitted.
5. If the service associated with the processing of a form has side effects (for example, modification of a database or subscription to a service), the method should be POST.6. Data is submitted in the form as specified in enctype attribute of form tag and thus files can be used in FileUpload input box.

C# Constructor

C# Constructor and its Types – A Detailed Look Definition: In simple terms, Constructor is a special kind of method with class name as method name and gets executed when its (class) object is created. This article will give you a detailed explanation on C# constructors and its types. Now, when we look at the above definition in a broader sense, a constructor is a class method that gets automatically executed whenever class’s object is created or whenever class is initialized.   Consider following bit of code: public class MsDotNetHeaven     {         public MsDotNetHeaven()          {               //A default Constructor          }       //Class members     } In the above snippet, the method MsDotNetHeaven() is called the constructor of class MsDotNetHeaven, also called default constructor. Behind the scenes What happened behind the scenes : whenever you try to create an object of class or initialize a class, then the default constructor will be automatically i

Hiding vs Overriding

As most of you know hiding and overriding are two main features based upon inheritance, which is one of the pillars of the OOP. Using these we can redefine a member of the base class in a derived class. But what are the differences. Let me clear this with a simple example. Start a new web application project with a default web form named "WebForm1" using visual studio. Add 2 class to this project with names "BaseClass" and "DerivedClass". The "DerivedClass" should be a subclass of "BaseClass" (i.e. should define like DerivedClass: BaseClass). Define the following functions in the base class named "BaseClass".  Notice the keyword "virtual".   public   virtual   string  FunctionToOverride() {            return  "This is from base class FunctionToOverride"; } public   string  FunctionToHide() {            return  "This is from base class FunctionToHide"; } Now define th
