The basic Dot Net Interview Questions and Answers
1)What is .NET?
.NET is a free, open-source, cross-platform framework for building a wide variety of applications using different programming languages. It was developed by Microsoft, and provides a common set of libraries and tools that can be used to create and run applications on different platforms, including Windows, macOS, and Linux. It includes a runtime environment called the Common Language Runtime (CLR), which manages the execution of code, and a large library of pre-written code called the Framework Class Library (FCL), which can be used to perform common tasks such as data access, encryption, and networking.
2) What is .Net framework?
The .NET framework is a software development framework developed by Microsoft. It includes a large library of pre-written code and a runtime environment that allows developers to create Windows and web applications, as well as other types of software, in various programming languages such as C# and Visual Basic. The framework provides a common set of tools and libraries that can be used to create and run applications on different platforms, including Windows, macOS, and Linux. The latest version of the .NET framework is .NET 7.
3) What languages does the .NET Framework support?
.NET supports various programming languages such as C#, F#, and Visual Basic. It also has been evolving to be more cloud native, open, and cross-platform. The latest version of .NET is .NET 7.
4) What are the most important aspects of .NET?
.NET is a software framework developed by Microsoft that allows for the creation of applications for Windows, the web, and mobile devices. Some of the most important aspects of .NET include:
Common Language Runtime (CLR): This is the virtual machine that manages the execution of .NET applications, providing features such as memory management, security, and exception handling.
Class Library: This is a collection of pre-written code that can be used by developers to perform common tasks, such as reading and writing files, connecting to databases, and creating user interfaces.
C# and Visual Basic: These are the two main programming languages supported by .NET, both of which are designed to be easy to learn and use.
Platform independence: With .NET 5 and later, it allows developers to build applications that can run on multiple platforms like Windows, Linux, and macOS.
Interoperability: .NET allows for seamless interaction between different programming languages and libraries, enabling developers to use the best tools for the job.
Security: .NET provides built-in security features such as code access security and role-based security, which help to protect against common security threats.
Scalability: .NET is designed to scale to meet the demands of large, complex applications, and it can be easily integrated with other technologies such as Azure for cloud computing.
Object-oriented programming (OOP) is a programming paradigm that is based on the concept of "objects", which are instances of classes that encapsulate data and behavior.
The key principles of OOP include:
Encapsulation: This refers to the practice of keeping an object's internal state and behavior hidden from the outside world, and only exposing a public interface for interacting with the object.
Inheritance: This refers to the ability for a class to inherit properties and methods from a parent class, allowing for code reuse and abstraction.
Polymorphism: This refers to the ability for different objects to respond to the same method or property in a way that is appropriate for their specific type.
The .NET Framework is built on these principles of OOP, and it provides a rich set of classes and libraries that can be used to create object-oriented applications. C# and Visual Basic are the two main programming languages supported by the .NET Framework, both of which are designed to be easy to learn and use, with OOP concepts and syntax.
Many of the classes in the .NET Framework are designed to be inherited from, and they use polymorphism to allow for a high degree of flexibility and extensibility. The framework also provides a number of built-in features that support OOP, such as garbage collection, which automatically manages the memory used by objects, and reflection, which allows for runtime inspection of objects and their properties.
In summary, OOP is a programming paradigm that is based on the concept of objects and the .NET Framework is a software framework which is built on this paradigm and provides a rich set of classes and libraries that can be used to create object-oriented applications.

How to Use CDATA in XML?
XML parsers normally parse all the text in an XML document.
When an XML element is parsed, the text between the XML tags is also parsed:
<message>This text is also parsed</message>The parser does this because XML elements can contain other elements, as in this example, where the <name> element contains two other elements (first and last):
<name><first>Bill</first><last>Gates</last></name>and the parser will break it up into sub-elements like this:
<name>Parsed Character Data (PCDATA) is a term used about text data that will be parsed by the XML parser.
<first>Bill</first>
<last>Gates</last>
</name>
CDATA - (Unparsed) Character Data
The term CDATA is used about text data that should not be parsed by the XML parser.Characters like "<" and "&" are illegal in XML elements.
"<" will generate an error because the parser interprets it as the start of a new element.
"&" will generate an error because the parser interprets it as the start of an character entity.
Some text, like JavaScript code, contains a lot of "<" or "&" characters. To avoid errors script code can be defined as CDATA.
Everything inside a CDATA section is ignored by the parser.
A CDATA section starts with "<![CDATA[" and ends with "]]>":
<script>In the example above, everything inside the CDATA section is ignored by the parser.
<![CDATA[
function matchwo(a,b)
{
if (a < b && a < 0) then
{
return 1;
}
else
{
return 0;
}
}
]]>
</script>
Code:
- string CDATAStart = "<![CDATA[", CDATAEnd = "]]>";
- LongDescription = CDATAStart + mcLongDescription.Trim() + CDATAEnd;
A CDATA section cannot contain the string "]]>". Nested CDATA sections are not allowed.
The "]]>" that marks the end of the CDATA section cannot contain spaces or line breaks.

How to Add Active Navigation Class Based on URL?
Let's say you have navigation like this:
HTML:
- <nav>
- <ul>
- <li><a href="/">Home</a></li>
- <li><a href="/about/">About</a></li>
- <li><a href="/clients/">Clients</a></li>
- <li><a href="/contact/">Contact Us</a></li>
- </ul>
- </nav>
And you are at the URL:
http://yoursite.com/about/team/
And you want the About link to get a class of "active" so you can visually indicate it's the active navigation.
jQuery:
- <script type="text/javascript">
- $(function () {
- var page = location.pathname.split("/")[1];
- if (page != "") {
- $('nav a[href^="/' + page + '"]').parent().addClass('active');
- }
- });
- </script>
JavaScript:
- <script type="text/javascript">
- (function() {
- var nav = document.getElementById('nav'),
- anchor = nav.getElementsByTagName('a'),
- current = window.location.pathname.split('/')[1];
- for (var i = 0; i < anchor.length; i++) {
- if(anchor[i].href == current) {
- anchor[i].className = "active";
- }
- }
- })();
- </script>
Essentially that will match links in the nav who's href attribute begins with "/about" (or whatever the secondary directory happens to be).

- = is equal
- != is not equal
