Answer: This is one of the most important typical question, which is asked in most of the interviews to check whether you know about generic. Generic: Generic help us to create flexible strong type collection. Generic basically seperate the logic from the datatype in order maintain better reusability, better maintainability etc. Lets see an simple example to understand how exactly generic seperate logic from datatype. In order to use Generic

Answer: Any project you take in .NET or any language reporting is an integral part of the application. You will rarely find application without reports. Due to heavy usage of reporting in application this topic becomes a hot favorite of interviewers.  There are two prominent technologies by which you create reports in .NET one is crystal reports and the other is SQL reporting services.  In this question we will try to answer from the crystal report point of view

Answer:  This is a typical .Net interview question which is asked to understand if you know how to create deployment packages. When you are done with your application you would like to give your end user a setup package rather than the source code. The short answer which the interviewer is expecting is that we can use the Visual studio deployment package project. Now the long answer just in case the interviewer gets in to details. So lets understand step by step of how to c

Answer: Let’s demonstrate an example to prove that how arrays are faster than arraylist for that go to visual studio and create a simple window application with a button and two labels like below diagram.   Below is the code snippet.   using System.Collections;// import this namespace to access arraylist. using System.Diagnostics;// import this namespace to access Stopwatch. namespace ArrayandArrayList { public partial class Form1 : Form

Answer:   Array   ArrayList   They are fixed length.   They are resizable and variable length.   They are compiled strong type collection.   They are flexible and can accommodate any data types.   Because arrays are of fixed size and strong type collection performance is faster.   In arraylist lots of boxing and unboxing are done there f

Answer:   Collection: - Collections are basically group of records which can be treated as a one logical unit. .NET Collections are divided in to four important categories as follows. Indexed based. Key Value Pair. Prioritized Collection. Specialized Collection.   Let’s begin with Indexed based and key value pair.   Indexed based: - It helps you to access the value of row by using the inte
