Accenture DOT NET Developer Interview Questions and Answers

The .NET application code is compiled into Intermediate Language (IL) which is then executed by the Common Language Runtime (CLR).

• Code is compiled into Intermediate Language (IL) by the compiler

• IL is then converted into machine code by the Just-In-Time (JIT) compiler

• The CLR manages memory, security, and other system resources during code execution

GC stands for Garbage Collection, a process in .NET to automatically manage memory by reclaiming unused objects.

• GC is a feature in .NET that automatically manages memory by reclaiming unused objects.

• It helps in preventing memory leaks and improving application performance.

• GC can be used in .NET applications to free up memory occupied by objects that are no longer needed.

A self join in SQL allows a table to be joined with itself to compare rows within the same table.

• Self joins are useful for hierarchical data, like employee-manager relationships.

• Example: To find employees and their managers, you can join the Employees table on itself.

• SQL syntax: SELECT a.EmployeeID, a.Name, b.Name AS ManagerName FROM Employees a JOIN Employees b ON a.ManagerID = b.EmployeeID;

• Self joins can be used...read more

SQL query example

• Specify the table name after the FROM keyword

Boxing is the process of converting a value type to the object type, while unboxing is the reverse process.

• Boxing is done implicitly when a value type is assigned to an object variable.

• Unboxing is done explicitly by casting the object back to its original value type.

• Boxing and unboxing can have performance implications and should be used judiciously.

• Example: int num = 10; object obj = num; // Boxing, converting in...read more

CLR stands for Common Language Runtime, it is used to manage the execution of .NET programs.

• CLR is a part of the .NET framework responsible for managing the execution of .NET programs.

• It provides services such as memory management, exception handling, and security.

• CLR converts the Intermediate Language (IL) code into machine code during runtime.

• It allows for language interoperability, meaning different languages c...read more

Object-oriented programming (OOP) is a programming paradigm that uses objects to represent and manipulate data.

• OOP focuses on creating reusable code by organizing data and behavior into objects.

• It emphasizes concepts like encapsulation, inheritance, and polymorphism.

• Objects have attributes (data) and methods (functions) that can interact with each other.

• Example: In C#, classes are used to define objects and their ...read more
