Difference between array, arraylist, List, Hashtable, Dictionary and SortedList in c#

-
Basic difference is that arrays are of fixed size. Whereas an ArrayList implements the list data structure and can dynamically grow. While arrays would be more performance that a list, a list would be far more flexible since you don't need to know the required size initially. Array - represents an old-school memory array - kind of like a alias for a normal type[] array. Can enumerate. Can't grow automatically. I would assume very fast insertion, retrieve and speed. ArrayList - automatically growing array. Adds more overhead. Can enum., probably slower than a normal array but still pretty fast. These are used a lot in .NET List - one of my favorites - can be used with generics, so you can have a strongly typed array, e.g. List . Other than that, acts very much like ArrayList. Hashtable - plain old hashtable. O(1) to O(n) worst case. Can enumerate the value and keys properties, and do key/val pairs. Dictionary - same as above only strongly typed via generics, such a...

All about Angular UI Bootstrap framework

Angular UI Bootstrap

AngularUI Bootstrap, as name says, is built on top one of the most popular front-end frameworks, Bootstrap. The goal is to provide native AngularJS directives without any dependency on jQuery or Bootstrap's JavaScript. It is often better to rewrite an existing JavaScript code and create a new, pure AngularJS directive. Most of the time the resulting directive is smaller as compared to the original JavaScript code size and better integrated into the AngularJS ecosystem.

Installation

Installation is easy as UI Bootstrap has minimal dependencies - only the AngularJS and Twitter Bootstrap's CSS are required. Notes:
•Sincer version 0.13.0, UI Bootstrap depends on ngAnimate for transitions and animations, such as the accordion, carousel, etc. Include  ngAnimate  in the module dependencies for your app in order to enable animation.
•UI Bootstrap depends on ngTouch for swipe actions. Include  ngTouch  in the module dependencies for your app in order to enable swiping.

Angular Requirements
•UI Bootstrap 1.0 and higher requires Angular 1.4.x or higher and it has been tested with Angular 1.4.8.
•UI Bootstrap 0.14.3 is the last version that supports Angular 1.3.x.
•UI Bootstrap 0.12.0 is the last version that supports Angular 1.2.x.

Bootstrap Requirements
•UI Bootstrap requires Bootstrap CSS version 3.x or higher and it has been tested with Bootstrap CSS 3.3.6.
•UI Bootstrap 0.8 is the last version that supports Bootstrap CSS 2.3.x.

Install with NPM

$ npm install angular-ui-bootstrap

This will install AngularJS and Bootstrap NPM packages.

Install with Bower

$ bower install angular-bootstrap

Note: do not install 'angular-ui-bootstrap'. A separate repository - bootstrap-bower - hosts the compiled javascript file and bower.json.

Install with NuGet

To install AngularJS UI Bootstrap, run the following command in the Package Manager Console

PM> Install-Package Angular.UI.Bootstrap

Custom build

C# Interview Questions on Inheritance

-
What are the 4 pillars of any object oriented programming language? 1. Abstraction 2. Inheritance 3. Encapsulation 4. Polymorphism Do structs support inheritance? No, structs do not support inheritance, but they can implement interfaces. What is the main advantage of using inheritance? Code reuse Is the following code legal? class ChildClass : ParentClassA, ParentClassB { } No, a child class can have only one base class. You cannot specify 2 base classes at the same time. C# supports single class inheritance only. Therefore, you can specify only one base class to inherit from. However, it does allow multiple interface inheritance. What will be the output of the following code? using System; public class BaseClass { public BaseClass() { Console.WriteLine("I am a base class"); } } public class ChildClass : BaseClass { public ChildClass() { Console.WriteLine("I am a child class"); } static void Main() { ChildClass CC = new ChildClass(); } } Output: I am a base clas...

C# Interview Questions on value types and reference types

-
What are the 2 types of data types available in C#? 1. Value Types 2. Reference Types If you define a user defined data type by using the struct keyword, Is it a a value type or reference type? Value Type If you define a user defined data type by using the class keyword, Is it a a value type or reference type? Reference type Are Value types sealed? Yes, Value types are sealed. What is the base class from which all value types are derived? System.ValueType Give examples for value types? Enum Struct Give examples for reference types? Class Delegate Array Interface What are the differences between value types and reference types? 1. Value types are stored on the stack where as reference types are stored on the managed heap. 2. Value type variables directly contain their values where as reference variables holds only a reference to the location of the object that is created on the managed heap. 3. There is no heap allocation or garbage collection overhead for value-type variables. As ...
