There are multiple ways to send data from View to controller in ASP.NET MVC, including form submission, AJAX calls, query strings, and model binding.

• Form submission using HTML forms

• AJAX calls using jQuery or other JavaScript libraries

• Query strings in the URL

• Model binding in ASP.NET MVC

I follow OOPS concepts by using inheritance, encapsulation, polymorphism, and abstraction in my code.

• I use classes and objects to encapsulate data and behavior.

• I utilize inheritance to create a hierarchy of classes with shared attributes and methods.

• I implement polymorphism by overriding methods in derived classes.

• I apply abstraction to hide complex implementation details from the user.

Database is connected using Entity Framework in current project. Yes, we can update multiple databases using DbSet.

• Database is connected using Entity Framework which provides a data access layer for interacting with the database.

• DbSet is a collection of entities that can be queried, updated, inserted, and deleted in the database.

• By using DbSet, we can update multiple databases by specifying the database context for each operation.

• Example: dbContext1.Set().Add(entity); dbConte...read more

Implementing a new feature to automate data migration process

• Developing a custom data migration tool using C# and SQL Server

• Creating scripts to extract data from legacy system and load into new system

• Testing the tool with sample data to ensure accuracy and efficiency

I test features after implementation by conducting unit tests, integration tests, regression tests, and user acceptance tests.

• Conduct unit tests to ensure individual components work correctly

• Perform integration tests to check interactions between components

• Run regression tests to verify that new features do not break existing functionality

• Conduct user acceptance tests to ensure the feature meets user requirements

Filters in MVC are used to perform logic before or after an action method is executed.

• Filters can be used for authentication, authorization, logging, exception handling, etc.

Use recursion to print numbers from 100 to 1 without using loops.

• Create a recursive function that prints the number and calls itself with the next number until reaching 1.

• Base case should be when the number is 1, then stop recursion.

• Example: void printNumbers(int n) { if(n == 0) return; print(n); printNumbers(n-1); }

Abstraction focuses on hiding complex implementation details, while encapsulation bundles data and methods into a single unit.

• Abstraction allows us to focus on the essential features of an object while hiding unnecessary details. For example, a car can be abstracted as a vehicle with properties like speed and color.

• Encapsulation involves bundling data and methods that operate on the data into a single unit. For example, a class in object-oriented programming encapsulates data...read more

Clustered indexes physically reorder the data in the table, while non-clustered indexes create a separate structure.

• Clustered indexes determine the physical order of data rows in a table.

• Non-clustered indexes create a separate structure that contains a copy of the indexed columns and a pointer to the actual data rows.

• Tables can have only one clustered index, but multiple non-clustered indexes.

• Clustered indexes are faster for retrieval operations, while non-clustered indexes a...read more

LEFT Join example in LINQ and SQL

• In LINQ, use the 'DefaultIfEmpty' method to perform a LEFT JOIN

• In SQL, use the 'LEFT JOIN' keyword to combine rows from two tables based on a related column
