Hello World Program in C# Programming Language

 Here's an example of a "Hello, World!" program in C#:
csharp
using System; 
class HelloWorld 
{ 
static void Main() 
{ 
 Console.WriteLine("Hello, World!"); 
 } 
}

The using System; statement is used to include the System namespace, which contains the Console class that is used for input and output operations. The class HelloWorld statement defines a new class named HelloWorld. The static void Main() method is the entry point of the program, and it is where the execution of the program begins. The Console.WriteLine("Hello, World!"); statement is used to print the "Hello, World!" message to the console. Finally, the program ends when the Main() method completes.

When you compile and run this program, you should see the "Hello, World!" message printed to the console.

Note that in C#, the entry point of the program must be a Main() method within a class. Also, the Console.WriteLine() method is used to print output to the console, and the semicolon at the end of the statement is required.
