✅ Foreach Loop Printing Multiple Chars from a String Simultaneously

string s = "Hello World";
foreach(char ch in s)
    {
         Console.WriteLine(ch);
    }

string s = "Hello World";
foreach(char ch in s)
    {
         Console.WriteLine(ch);
    }

Prints

He
l
l
o
 
W
o
r
l
d

He
l
l
o
 
W
o
r
l
d

Surely H and e shouldn't be printed on the same line? What am I misunderstanding here?

It works fine

AdiZOP•13mo ago

Weird. Online C# compilers are evidently not the way to go.

Angius•13mo ago

They do have their quirks Although the reputable ones like Sharplab should work just fine

AdiZOP•13mo ago

Do I need to set this thread to resolved or something?

Angius•13mo ago

You can use /close if you want

AdiZOP•13mo ago

I'll check that out. Thanks.

Angius•13mo ago

Ideally, though, just run the code locally

AdiZOP•13mo ago

Ah perfect. Thanks for the super speed reply 🙂

Angius•13mo ago

Much better experience

AdiZOP•13mo ago

Yeah I'm struggling to make it work in VS Code, only works in VS 2022 right now. Could you help me figure it out?

Angius•13mo ago

Sure $vscode

Follow the instructions here on getting started with DevKit for C# in VSCode: https://code.visualstudio.com/docs/csharp/get-started

I don't know how to make a program run, it just says that I haven't created a project, but I've no clue how to do that.

Angius•13mo ago

Ah, well, C# is project-based Not file-based like Python or PHP

AdiZOP•13mo ago

Interesting. So how can I create one in VS Code?

Angius•13mo ago

You can't run just a loose myprogram.cs file dotnet new command dotnet new console for example, will create a CLI project

AdiZOP•13mo ago

In the VS Code console?

Angius•13mo ago

Yep

AdiZOP•13mo ago

Awesome gimme two secs I'll go try that

Angius•13mo ago

It will create a Program.cs and MyCoolProject.csproj files, which is the minimum needed for a C# project to work

AdiZOP•13mo ago

I imagine this will be an issue?

Angius•13mo ago

Huh I guess install Powershell...?

AdiZOP•13mo ago

It's a school computer and powershell is blocked. Probably that? It works for Unity soo

Angius•13mo ago

Ah, could be

AdiZOP•13mo ago

Does Unity not use .NET?

Angius•13mo ago

It uses its own weird fork of Mono, last I checked They are working on migrating to .NET 6, I believe

AdiZOP•13mo ago

Is that the MonoBehavior identifier next to all the scripts' classes?

Angius•13mo ago

But they're taking their time, .NET 8 came out today lol No, MonoBehavior would be the base class : is inheritance

AdiZOP•13mo ago

Haha yeah I was about to say, why not at least .NET 7 Ahhhh so that's how inheritance works.

Angius•13mo ago

class MyThing : MonoBehavior means MyScript inherits MonoBehavior
