The concept of function within a function, like we normally do inside a class.

We will create a method GetName() .

The code will look like the following.

static void Main(string[] args)  {     Console.WriteLine("Name is: " + GetName());  }  public static string GetName()  {    return "Name";  }  

Next, we need to add more , will create Function called GetFullName() , will call 2 methods GetFName() and GetLName. 

This result will be added to the GetFullName() and the complete result will be returned.

The main point here is that if we create a public method to concate our string togather, it will be globally available. If we create a private method, the method will be available to other methods as well, which is not required. So, what we will do is create the method as a sub-method within the GetFullName function. This will be created like any other normal function. So, the code will look like the following.

namespace ConsoleApplication1  {      class Program      {          static void Main(string[] args)          {              Console.WriteLine("Full Name is: " + GetFullName());          }          public static string GetFullName()          {              var FullName= GetFName() + " " +GetLName();                return FullName;                          string GetFName()              {                  return "First Name";              }              string GetLName()              {                  return "Last Name";              }          }      }  

 we have created another two methods GetFName() and  GetLName() within a function to return FullName().

AngularJS is a client-side JavaScript framework developed by Google and the community for developing single-page applications that only require CSS, HTML and JavaScript on the client side.

Features

• Directives
• Data Binding
• Filters
• Modules
• Routes
• Controllers

AngularJS Directives

AngularJS Directives are commands that allow the developer to specify custom and reusable HTML tags that moderate the behavior of certain elements as in the following:

• ng-app: It will load the dependencies and the module.
• ng-bind: Automatically changes the text of an HTML element to the value of a given expression.
• ng-model: Similar to ng-bind, but allows two-way data binding between the view and the scope.
• ng-class: Allows class attributes to be dynamically loaded.
• ng-controller: Specifies a JavaScript controller class that evaluates HTML expressions.
• ng-repeat: Angular control structure act as for loop.
• ng-click: Angular on click event

Install: Open the website angularjs.

Download

Now select Branch and build if you want to uncompress or Zip. And click Download. 

Getting Started

• Start Visual Studio
• Create a new website
• Provide the name and location of website
• Click "Next"

Add angular.min.js to the scripts directory.

Now let's work on the view part.

To begin let's see how to do data binding using AngularJS:

First of all add a new HTML page and provide a relevant name, now add a angularjs reference to the page.

<script src="Scripts/angular.min.js"></script>

Now add the ng-app directive on the top root of the page or in any div like this.

<html ng-app=""><div class="container" ng-app="">Let's<div class="container" ng-app="">        <h3>AngularJS Data Binding Template </h3>               Name: <input type="text" ng-model="name" placeholder="Type something" />&nbsp;&nbsp; {{ name }}        <br />        Country: <input type="text" data-ng-model="country" placeholder="Type something" />&nbsp;&nbsp; {{ country }}</div>

One more example that calculates 2 numbers:

<div>        <h3>AngularJS Data Binding Template</h3>        <input type="number" ng-model="FirstValue" value="0" placeholder="Enter First value here">        +        <input type="number" ng-model="SecondValue" placeholder="Enter Second value here">        ={{FirstValue+SecondValue}}</div><script src="Scripts/angular.min.js"></script>
