C# - Can't add two double values with each other

Question

I'm new to programming and I'm trying to create a simple calculator program where I can add two different double values with each other. But I'm having this problem:

        Console.Write("First Number: ");
        double number1 = Convert.ToDouble(Console.ReadLine());

        Console.Write("Second Number: ");
        double number2 = Convert.ToDouble(Console.ReadLine());

        Console.WriteLine(number1 + number2);

For instance, let's say that I typed 10 and 2.5 I want the program to print out 12.5 but instead it prints out 35

-RESULT-

enter image description here

Are you sure the conversion is occurring as you expect? Try printing the values of `number1` and `number2` before adding them (or view in a debugger) — h0r53, Sep 15 '21 at 18:27
In Turkey decimal separator is "," string "2.5" is parsed as 25. — lidqy, Sep 15 '21 at 18:38
To improve your future questions please review [MCVE] guidance on posting code. In this particular case `var number = Convert.ToDouble("3.5");` is all code that is necessary to demonstrate the problem. — Alexei Levenkov, Sep 15 '21 at 18:39

Try to write ',' instead '.' or change keyboard layout

It was an issue with decimal separators. I tried using comma and it worked. Thanks everyone for helping out – Emirhan Sep 15 '21 at 18:49
