confusion about code

Question

Hi

I am new to C#, I just finished watching a part of a tutorial. I am confused about a line of code, which I did not understand. here is the code,

int userValue = 2;
string message = (userValue == 1) ? "boat" : "car";
Console.WriteLine("{1} - {0}", userValue, message);
Console.ReadLine();

output: car - 2

 

my question is for line 3. why its print "car" first? shouldn't it be "2" first?

because it says here

 

Console.WriteLine("{1} - {0}", userValue, message);  

 

doesn't it mean {1} assign to 'userValue' & {0} assign to 'message'? 

I am really confused here. 

I am sorry if I post this question in wrong section.

 

thanks
