Use Console.WriteLine to print the contents of the firstName variable to the screen

string firstName = "Bob"; Console.WriteLine("Your first name is: " + firstName);

CodeChallenge.cs 
string firstName = "Bob";
System.Console.WriteLine("The name you entered is: " + firstName);

I've tried several different codes. The first one followed the previous question. Here's my original answer and it still gives me an error. 

    Console.Write("Enter your name:  "); 
    string name = Console.ReadLine();
    string firstName = name;
    Console.WriteLine("Your name is : " + firstName);

Well, do one task at a time. And for task one, it doesn't ask for a Write or a WriteLine. Always do only what the challenge asks for. Doing anything extra can prevent the code from passing.

And the two lines in between might work, but why not use the correct variable name the first time and avoid the second assignment?

So what is the answer? I've tried the following:

string firstName = name; Console.WriteLine("Your name is: " + firstName);

or this

Console.Write("Enter your name: "); string name = Console.ReadLine(); string firstName = name; Console.WriteLine("Your name is : " + firstName);

or this 

string name = Console.ReadLine();
string firstName = name;
Console.WriteLine("Your name is : " + firstName);

or just this

string firstName = "Bob";
Console.WriteLine("Your name is : " + firstName);

funny thing is on the Workspace is works! The quiz has a bug!

The challenge isn't just about writing code that works .. you need to write code that does the right thing.

Remember, I already reminded you that for task 1 there will be no "Write" and no "WriteLine". You will only need one line of code, which will create a variable and assign it using "ReadLine".

Step 1:

string firstName = Console.ReadLine();

Step 2:

string firstName = Console.ReadLine();
Console.WriteLine(firstName);

Step 3:

string firstName = Console.ReadLine();
Console.WriteLine(firstName + " rocks!");

Hi Steven,

I felt your explanation covered the problem nicely. I thought I would provide the original poster with the answer as they explicitly asked for it, in the hope they would not get frustrated or discouraged and give up but instead is able to see their mistake and learn from it.

Thanks for informing me though, I will be careful in my future responses.

I'm not a fan of spoilers, but they are apparently allowed if accompanied by explanations.

I'm wondering if the "View Challenge" button is pointing to the right thing? The code shown here is very different from what that challenge is asking for!

When I select the button, the very first task says, "Declare a variable named firstName and initialize it to the string returned from a call to Console.ReadLine()." Other than the same variable name, the rest of this code doesn't go with these instructions at all.
