C# is an object-oriented programming language and in C# program runs from top to bottom.

Program in C#

Let’s see a simple program in CS. I suggest using visual studio for writing C# code. In c# we create a file with extension .cs for example: program.cs

Console.WriteLine("Hello, World!");
Console.ReadLine();

Console.WriteLine(“Hello, World!”); prints the value written inside it and Console.ReadLine() work is to pause the execution of the code to get the input value from the user. You need to hit the enter button to continue the code execution if you are writing Console.ReadLine();

In C#, we write methods inside the classes. A single class contains different methods inside it. For example:

Class
 Method1
 Method2
 Method3
 Method4

Then, there are namespace in c#. We store the class in the related namespace. For example

namespace
 class1
 class2
 class3
 class4

Then, there are assemblies in c#. assemblies contain namespace. For example

Assemblies
 namespace
 namespace
 namespace
 namespace
