Type Casting is the mechanism to convert one data type to another. While type casting of one data type to another, we get exception if the previous one data type is not compatible with the new data type. To avoid this exception, we have IS and AS operator in C# for safe type casting. Let's understand how to use both of them...
IS operator check for Object Type.
AS operator convert between compatible type Object.

Q1: Directives can be applied to which all element type?
Ans: Following represents the element type and directive declaration style:
`E` – Element name: `
`A` – Attribute (default): ``
`C` – Class: ``
`M` – Comment: ``
Method chaining is a technique that can be used to simplify code in scenarios that involve calling multiple functions on the same object consecutively. This is an example of how you can use method chaining
when using jQuery.
AngularJS contains the following core types of objects and components:
These core types can be injected into each other using AngularJS dependency injection mechanism. Throughout the rest of this text I will explain how to define and inject these components into each other.
“M” “V” “C” stands for “MODEL” “VIEW” “CONTROLLER”. ASP.NET MVC is an architecture to develop ASP.NET web applications in a different manner than the traditional ASP.NET web development. Web applications developed with ASP.NET MVC are even more SEO (Search Engine) friendly.
Developing ASP.NET MVC application requires Microsoft .NET Framework 3.5 or higher.
You can implement the following types of directives:
- Element directives
- Attribute directives
- CSS class directives
- Comment directives
Of these, AngularJS recommends that you try to use element and attribute directives, and leave the CSS class and comment directives (unless absolutely necessary).
The type of a directive determines how the directive is activated. An element directive is activated when AngularJS finds a matching HTML element in the HTML template. An attribute directive is activated when AngularJS finds a matching HTML element attribute. A CSS class directive is activated when AngularJS finds a matching CSS Class. And, a comment directive is activated when AngularJS finds a matching HTML comment.
Now a days in interview in C# this question is frequently ask that " What is the difference between ref and out parameter". In C#, a method can return only one value. If you like to return more than one value, you can use the ref & out keyword Here I will explain that....
Parameters are always passed by value to a method by default.If we want to pass them by reference then we can use either out or ref keyword.
Reference parameters basically never pass the value of a variable used in the method calling, instead they use the variable themselves. Rather than creating a new storage for that variable in the method declaration, the very same storage space is used, so the value of the variable in the member method and the value of the reference parameter will always be the same. Reference parameters require ref modifier as part of both the declaration and the calling.
Output parameters are very much like reference parameters. The variable specified at the time of calling doesn't need to have been assigned a value before it is passed to the called method. When the method is invoked completely we can read that variable as it is assigned by now.
Like reference parameters, output parameters don't create a new storage location, but use the storage location of the variable specified on the invocation. Output parameters need the out modifier as part of both the declaration and the invocation - that means it's always clear when you're passing something as an output parameter.
