C# C# Basics (Retired) Perform Converting Strings to Integers

I cant write int with a dot followed after "int" when i try to enter int.Parse("xx")

Whenever I write the dot (.) after "int" in the console it immediately gives me an error and won't allow me to complete the line. It says "Unhandled exceptions" followed by "System.ArgumentException: Cannot be less than one" in the next line, which is then followed by 33 lines of text saying something like "Mono.Terminal.LineEditor.UpdateCompletionWindow......"

To follow up it also exits me out of the repl and back to the regular console

Just to be sure, you're typing this in at the "csharp>" prompt, right? I don't seem to be able to replicate the symptom.

When I type the peroid, I get a little helper box with a list of possible things to put next, starting with "CompareTo". It doesn't exit, even if I type the complete line and get the (expected) error.

This might be an issue to take up with the Support staff.


I've attached a link to a picture showing what happens when I write "int."

I've also highlighted the line where i write "int." (in the picture)

Ill also try to contact support, thank you for the advice. I actually thought this was support :p

Well, this is the place to come for support from other students. But for anything official it's good to contact the staff directly.

Well, this is embarrassing. It works now so i think i just needed to restart the workspace. Thanks for the help anyway :)
