C# C# Collections Arrays Multidimensional Arrays

C# The type or namespace 'Cell' could not be found.

when trying to use Cell[,] to initialize a multidimensional array I get the error in the csharp repl: The type or namespace 'Cell' could not be found. I also get the same message when trying to compile code in Visual Studio. Is there an import or something needed?

You have to first define that "Cell" class, it's not something defined in .net already. Enter in the repl what the Cell class should be, maybe something like: public class Cell { public string Data { get; set; } }

or anything else you want that cell to contain.

Jeremy McLain : is this something you can update in the teacher's notes? Especially since this lesson starts a new workspace?

Step to Type in the console before starting this video: (See video "Jagged Arrays" Starting at 0:40)

✔Step 1 : (Type csharp in console)

treehouse:~/workspace$ csharp
Mono C# Shell, type "help;" for help

✔Step 2: (Create Cell class with getter and setter)

Enter statements below.
csharp> class Cell
> {
> public string Contents { get; set; }
> }

I hope this helps! 🐱‍🏍
