Issue with C# "Getting User Input"

Question

Hi everyone, there is an issue with this code excersise as I have tried running it by the following:

string yourName;
Console.WriteLine("What is your name?");
yourName = Console.ReadLine();
Console.WriteLine("Hello {0}, yourName");

What happens is that it just prints out "Hello {0}" and not the variable yourname where {0} is. I'm not sure what is wrong but help would be grateful.

There is also an error with the following code:

int age = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("You are {0} years old, age");
