What is C#?

Relax. We'll talk through this in plain words — no textbook voice.

C# is a modern, object-oriented, type-safe programming language created by Microsoft. Type-safe means the compiler checks what kind of data goes into a variable. For example, if youint try to put text into an, it'll warn you before the program even runs.

csharp

// C# program တစ်ခုက class ထဲက Main method မှစတင်အလုပ်လုပ်ပါတယ်။
using System;

namespace HelloWorld
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Hello from C#!");
        }
    }
}

What this code does

using System; brings in built-in tools like Console so you can use them.
namespace organizes your code into groups, kind of like folders.
class Program is where you write the program's logic.
Main method is where the app starts running.
Console.WriteLine() prints a line of text to the terminal.

🔎 Watch out for

In C#, most statements end with a semicolon ;. Forget it, and the compiler will immediately complain.
