Question

Console.WriteLine("Enter a double number");
string numberInput = Console.ReadLine();


 double number = Double.Parse(numberInput) 

My question is what is the last line of code doing? Is it doing the same thing as ToDouble?

Answer 1

The very short answer is:

Converts a string value into a double. e.g.

“2.3”(String) will become 2.3(double).

You have many choices on how to do this:

Double.TryParse()

Convert.ToDouble()

Double.TryParse() is handy if you don’t know 100% that the input string is going to be a number value.
