(63,26) ConsoleWriteLine does not exist in the current context. Help?

I've tried moving the ConsoleWriteLine into the Try block but no dice (at least the way I am doing it.) The ConsoleWriteLine the error is reffering to is the second to last one: ConsoleWriteLine("That is not a valid entry."); continue;

(I think)

Anyone? If I need to paste all of my code please let me know. Thanks in advance.

Jude

try { //Add minutes exercised to total int minutes = int.Parse(userEntry);

                      if(minutes <0)
                      {
                        Console.WriteLine(minutes + " is not an acceptable value.");
                        continue;
                      }
                      else if(minutes <= 10)
                      {
                        Console.WriteLine("Better than nothing, am I right?");
                      }
                      else if(minutes <= 30)
                      {
                        Console.WriteLine("Way to go hot stuff!");
                      }
                      else if(minutes <= 60)
                      {
                        Console.WriteLine("You must be a Ninja Warrior in training!");
                      }
                      else
                      {
                        Console.WriteLine("Okay, now you are just showing off.");
                      }


                       //Add minutes exercised to total
                       runningTotal = runningTotal + minutes;

                   }
                    catch(FormatException)
                   {
                     ConsoleWriteLine("That is not a valid entry.");
                     continue;
                   }   
                        //Display running total of minutes exercised on screen
                        Console.WriteLine("You have exercised a total of " + runningTotal + " minutes.");

                }

A better way to share code (and the entire environment) is to make a snapshot of your workspace and post the link to it here.

This issue is not related to the "try" block. The mostly likely cause of this error would be a missing "using System;" directive at the top of the file.

Alternately, you could change all instances of "Console.WriteLine" to "System.Console.WriteLine".

Thank you Steven! I will use snapshot for sure and work on the other suggestions now. Course is great FYI.

Yup - that worked. commented out the using System; and them added System where needed. I also found a...spelling mistake? Syntax error?

Whatever you call it when you don't spell out your methods correctly.

Cheers,

Jude

The compiler may call it a syntax error. I'd call it a spelling error or typo.
