C# CLR

The Common Language Runtime (CLR) is a component of the Microsoft.NET Framework that manages the execution of .NET applications. It is responsible for loading and executing the code written in various .NET programming languages, including C#, VB.NET, F#, and others.

- When a C# program is compiled, the resulting executable code is in an intermediate language called Common Intermediate Language (CIL) or Microsoft Intermediate Language (MSIL). This code is not machine-specific, and it can run on any platform that has the CLR installed. When the CIL code is executed, the CLR compiles it into machine code that can be executed by the processor.

- The CLR provides many services to .NET applications, including memory management, type safety, security, and exception handling. It also provides Just-In-Time (JIT) compilation, which compiles the CIL code into machine code on the fly as the program runs, optimizing performance.

- Additionally, the CLR provides a framework for developing and deploying .NET applications, including a set of libraries, called the .NET Framework Class Library, which provides access to a wide range of functionality, such as input/output operations, networking, database connectivity, and user interface design.

C# | Association, Aggregation and Composition

Image
Association, Aggregation, and Composition are terms that represent relationships among objects. They are very basic stuff of Object-Oriented Programming. Association Association is a relationship among the objects. Association is "*a*" relationship among objects. In Association, the relationship among the objects determines what an object instance can cause another to perform an action on its behalf. We can also say that an association defines the multiplicity among the objects. We can define a one-to-one, one-to-many, many-to-one and many-to-many relationship among objects. Association is a more general term to define a relationship among objects. Association means that an object "uses" another object. For example, Managers and Employees, multiple employees may be associated with a single manager and a single employee may be associated with multiple managers. Aggregation Aggregation is a special type of Association. Aggregation is "*the*" relationship amo...

Throw vs Throw ex in C#

In C#, the   "throw"   keyword is used to throw an exception when an error occurs in your code. However, there are two variations of the   "throw"   statement:   "throw"   and   "throw ex" . We will look at the distinctions between   "throw"   and   "throw ex"   in C# in this article. In C#, the  "throw"  keyword is used to declare an exception. When an exception is thrown, the code that can handle it uses a catch block to capture it. The  "throw"  keyword is typically used to throw a new exception object, which can be created using the  "new"  keyword. For example, look at the below code: C# Code: try    {        // Some code that could potentially throw an exception    }   catch  (Exception ex)   {        // Handle the exception  ...

String[] args in C#

String[] args is a parameter of the Main method that represents the command-line arguments passed to the application when it is executed1. For example, if you run your application like this: MyApp.exe arg1 arg2 arg3 The args array will contain three strings: "arg1", "arg2", and "arg3". You can use the args array to access the command-line arguments and perform different actions based on them. For example, you can write a program that copies a file from one location to another by passing the source and destination paths as arguments1. Here is a simple example of how to use String[] args in C#: public   class Program  {       static void Main(string[] args)     {          Console.WriteLine("Number of arguments: " + args.Length);          foreach (string arg in args)         {             Console.WriteLine("Argument: " + arg);       ...
