Throwing Exceptions in c# In the C# programming language, exception errors are typically thrown when a user-defined program displays an error that prevents the current program from recovering from the error. C# users can use the throw keyword in their program source code to throw custom, user-defined, manual exception errors. Throwing any type of exception…
Try, Catch, Finally Block in c# In the C# programming language, the try, catch, and finally blocks are used to control or manage exception handling in multiple C# programs. Exception handling in C# is a process or mechanism that allows a C# program to detect any type of program error-specific exception generated at runtime and…
Introduction to LINQ in c# LINQ (Language Integrated Query) in the C# programming language is a collection of user-defined multiple class methods in a C# program. It provides a unified method for directly querying multiple types of class data sources (such as array data sequences, collection data types, database elements, XML file formats, etc.) in…
Lambda Expressions and Anonymous Methods Lambda expressions and anonymous class methods are advanced essential features in the C# programming language that allow C# programmers to define inline methods without requiring a formal class method declaration. Lambda expressions and anonymous C# methods allow programmers to pass program source code as arguments, which is useful for program…
Event Handling in c# Event handling in the C# programming language is a program-generated task process or mechanism that allows a particular portion publisher (event creator) of an existing C# program to indicate to another portion subscriber/user of the system that some system event or task generated action has been performed in the existing program.…
Difference Between Abstract Classes and Interfaces in c# In the C# programming language, both abstract classes and interfaces are class features or concepts used to declare or design a basic structure and class object prototype format or layout for a C# class program. However, both abstract classes and interfaces handle or manage multiple individual task…
Interface Definition and Implementation in c# In the C# programming language, an interface is a method of implementing a class object prototype, which defines a pre-defined set of new methods, properties, events, or indexers for the class, which must be implemented in a user-defined class or structure. A class interface cannot provide any implementations of…
Abstract Classes and Interfaces in c# In the C# programming language, both abstract classes and interfaces are OOPS concepts used to define or declare a class object or prototype, which is intended to be passed to derived or subclassed prototype objects within the same class. While they fulfil multiple individual purposes within existing classes, they…
Method Overloading and Overriding in c# In the C# programming language, method overloading and method overriding are two important features or concepts related to base class or subclass methods. While they generally appear similar, their purpose or use in C# programming differs for multiple individual programming tasks, and method overloading and method overriding are used…
Method Overriding and Virtual Methods in c# The method overriding concept in the C# programming language allows a derived class (user-defined subclass) to provide its own pre-defined implementation of a class function method already declared in the base root or parent class. A virtual method declared in the base class as a superclass allows the…
